ATS researchers fly and sail to stormiest place on Earth to study cloud processes

By ship and by plane, CSU Department of Atmospheric Science researchers recently ventured to the stormiest place on Earth, the Southern Ocean, to collect cloud, aerosol and precipitation data for a project known as SOCRATES. Knowledge gained during the Southern Ocean Clouds, Radiation, Aerosol Transport Experimental Study is expected to enhance weather and climate modeling and forecasting capabilities across the globe.

Graduate student Kathryn Moore, stationed aboard the research vessel (R/V) Investigator, collected data and samples to document primary ice nucleation and its influence on cloud phase. Primary ice nucleation is the formation of the first ice crystals in a cloud, which usually occurs on atmospheric aerosol particles known as ice nucleating particles, and cloud phase is the state of the cloud, liquid or ice.

“The SOCRATES project was designed to comprehensively sample and observe the interactions of aerosols with supercooled and mixed-phase clouds, to gain a better understanding of the aerosol-cloud interactions in this region, and to provide new datasets and parameterizations with which to test and improve weather and climate models,” Moore explained.

The research vessel embarked from Hobart, Tasmania on Jan. 11 and returned Feb. 22. Moore said the trip was remarkably smooth considering the region.

“There were about four to six days where waves were breaking over the bridge, six decks up, and it was too rough to get to the lab where the instruments were located. Other days varied from relatively flat, when we were close to the ice edge by Antarctica, up to six-meter swells. The Investigator has anti-roll tanks, which help reduce side-to-side motion, and I don’t suffer much from seasickness, which helps a lot when there are storms and high winds.”

Hands-on data collection was necessary to advance our understanding of cloud formation over the Southern Ocean because our current assessment is based almost entirely on satellite observations. This gap in knowledge leads to inaccurate climate models.

“The Southern Ocean is one of the most remote regions on Earth, far from anthropogenic and terrestrial aerosol sources, and so it is an ideal place to study natural aerosols and their interactions with clouds and radiation. Current weather and climate models struggle to represent this region,” Moore said.

CSU’s team of scientists had instruments aboard both the R/V Investigator, an Australian Marine National Facility research vessel, and HIAPER, or the High-performance Instrumented Airborne Platform for Environmental Research. HIAPER is a highly modified Gulfstream V jet that is owned by the National Science Foundation (NSF) and operated by the National Center for Atmospheric Research (NCAR) in Boulder. The project is a collaboration among U.S. universities and Australian scientists, with the U.S. portion funded by the NSF and supported by NCAR.

“It was truly a multinational campaign,” said senior research scientist Paul DeMott, who led the group from CSU. “Our CSU team role in general was to collect data to address an overarching hypothesis that cloud phase and lifetimes behind polar fronts in the Southern Ocean are controlled by ice nucleating particle populations unique to this region (partly due to ocean organic and biological particle emissions), with the consequence that this helps to explain errors in global climate model predictions of solar radiation reaching the ocean surface.”

Ice nucleating particles (INPs) are particles suspended in the atmosphere, which provide the foundation for the most common method of ice formation in the atmosphere. Though the INPs are very rare, they have strong control over the phase, liquid or ice, of a cloud. Once a cloud has glaciated, or turned from predominantly liquid to ice, its reflective properties and radiative effect change significantly, and it can begin to precipitate as snow or ice, rather than just rain.

DeMott shared flight scientist duties with recent CSU graduate Christina McCluskey, now an NCAR Advanced Study Program postdoctoral fellow. DeMott and McCluskey utilized two methods for assessing INP concentrations and a bioaerosol detector while flying over the Southern Ocean, just as Moore was collecting similar samples using the same methods at sea level, along with water samples.

“As expected, the concentrations of INPs over the Southern Ocean were some of the lowest on Earth, both in the marine boundary layer at the surface and higher up in the troposphere,” Moore said.

Still, the extraordinarily low numbers of INPs in the air were somewhat surprising to DeMott, as were some other discoveries.

“Clouds were also more multilayered than we anticipated, and this has implications for radiative transfer and satellite detection,” DeMott said.

Some flights had to be postponed or canceled due to unusual winds over Hobart, but DeMott said most flights were not especially turbulent.

“I only felt queasy once in the entire campaign. We primarily had to be mindful of two things – icing of the aircraft wings and instrument pods, and ingestion of too much sea salt into the engines.”

There were times the HIAPER had to climb above clouds or descend to dissipate accumulating ice. The flight crew also limited time spent at the lowest level over the ocean in high winds to avoid salt accumulation. At least once during the study, NCAR had the engines power-washed to remove salt buildup.

“I felt we were always safe, just a long way from home or a runway if anything had happened!” DeMott said.

Though their two months of scientific journeys by sky and by sea have come to an end, much of the work has just begun.

“Our job now is to process physical samples, analyze our own data and to integrate that with in situ data on cloud dynamics and microphysics, and remote sensing data on the same from the ships and aircraft toward answering key project science questions. It will be a massive collaborative effort,” DeMott said.

Research scientist Tom Hill and postdoctoral fellow Ezra Levin supported preparations and installations for the project, and Hill will play a major role in analyzing the collected aerosol samples.

“Some of our goals, once all the data and samples are analyzed, are to identify what the major sources of INPs in the Southern Ocean region are, characterize the biological species present through DNA analyses, and to develop a parameterization that describes INP emissions and atmospheric number concentrations that can be used in weather and climate models to improve predictions in this region,” Moore said.

Given the broad scope of the expedition and the vast amount of analysis yet to perform, discoveries and definitive conclusions are still on the horizon. However, according to DeMott, the SOCRATES project already has been a success.

“My takeaway was that we met the objective to perform the most comprehensive characterization of Southern Ocean clouds and aerosols yet undertaken, that our data sets are rich, and that we will be able to answer our major hypotheses.”

Thomas Vonder Haar co-authors book on founder of satellite meteorology

University Distinguished Professor Emeritus Thomas Vonder Haar has co-authored a book about Verner Suomi, the founder of satellite meteorology. Vonder Haar and six other authors drew on personal letters and oral histories of the Finnish-American educator, inventor and scientist to piece together Verner Suomi: The Life and Work of the Founder of Satellite Meteorology.

The book’s abstract explains how Suomi forever changed the field of meteorology:

“In the early days of space science, Suomi brought his pragmatic engineering skills to bear on finding ways to use our new access to space to put observational instruments into orbit. In 1959, his work resulted in the launching of Explorer VII, a satellite that measured Earth’s radiation budget, a major step in our ability to understand and forecast weather. Today, NOAA’s GOES system continues his legacy by providing a continuous stream of environmental data from space.”

“It was a pleasure to work with lead author and historian John Lewis and other colleagues on the new book,” Vonder Haar said. “[Suomi] was my Ph.D. advisor at the University of Wisconsin, and I worked closely with him on several research projects for 15 years beginning in 1963. Professor Suomi was a natural engineer and inventor with a deep understanding of global and local atmospheric systems.”

You can read more about the book or purchase it at the AMS Bookstore.

Eos features study led by Jack Kodros on health impacts of burning solid fuels

This week’s edition of AGU publication Eos featured a study led by Ph.D. candidate Jack Kodros on the health impacts of burning solid fuels. Associate Professor Jeff Pierce as well as several other researchers from CSU’s Walter Scott, Jr. College of Engineering contributed to the study.

In the absence of reliable access to electricity and clean cooking technology, nearly 40 percent of the world’s population burns solid fuels for cooking and home heating. Smoke particles produced by these fires are harmful to human health. While previous studies have estimated mortality from either household or ambient air pollution separately, Kodros’ study quantifies the combined effects of both. It targets gaps in knowledge that, once overcome, could lead to more accurate mortality estimates.

“The main goal of this study was to highlight specific data sources that contribute the most uncertainty to estimates of premature mortality. These data sources include statistics on how people die in different countries, the relationships between death and air pollution, and air pollution concentrations. We provide an estimate of which of these data sources should be the focus of future research in order to most improve our understanding of the global health impact of exposure to particulate matter,” Kodros explained.

Ultimately, it is important to communicate accurate estimates of premature mortality due to air pollution to policy makers, Kodros said.

Zitely Tzompa selected as inaugural Colorado Science and Engineering Policy Fellow

Ph.D. candidate Zitely Tzompa has been chosen to be among the first Colorado Science and Engineering Policy Fellows. The fellowship, recently created by State Representatives Chris Hansen and Bob Rankin, is an eight-week summer internship for STEM majors, where they will conduct policy research and learn more about STEM policies through seminars and industry site visits.

Public policy makers consult and collaborate with STEM experts for knowledge and advice in navigating the complex challenges of energy, water, public health and transportation. Fellows will observe this interaction and present their own capstone public policy projects, after undergoing a policy “boot camp” that will teach them about the policy-making process and the skills they’ll need to be a part of it.

Tzompa looks forward to gaining firsthand experience of how scientists can contribute to policy making.

“The best part of the fellowship is that I will have the opportunity to design, write and present my own policy proposal to legislators, industry figures and university representatives.”

Fellowship participants were sought from Colorado State University, University of Colorado Boulder, University of Denver, Metropolitan State and the Colorado School of Mines. Each school was allowed to place three fellows, and the Walter Scott, Jr. College of Engineering was assigned one of the spots. Two applications were selected at the college level and submitted to Hansen and Rankin. Tzompa and another Walter Scott, Jr. College of Engineering applicant then interviewed with the representatives at the Colorado State Capitol Building, and Hansen and Rankin made the final selection.

“The competition was fierce, but we were very impressed by what you could bring to the program,” read Tzompa’s notification from a member of Hansen’s staff.

The program, which runs May 21 through July 13, will be based mainly at the capitol building and will include field trips, seminars, workshops and social events. Fellows will receive a stipend.

Tzompa eagerly anticipates the impact the fellowship will enable her to make.

“This is an exciting time to be a scientist, and I look forward to contributing to both the scientific understanding and the environmental policy related to air quality.”

SOURCE: Distant tropical storms have ripple effects on weather close to home

The famously intense tropical rainstorms along the Earth’s equator occur thousands of miles from the United States. But atmospheric scientists know that, like ripples in a pond, tropical weather creates powerful waves in the atmosphere that travel all the way to North America and have major impacts on weather in the U.S.

These far-flung, interconnected weather processes are crucial to making better, longer-term weather predictions than are currently possible. Colorado State University atmospheric scientists, led by professors Libby Barnes and Eric Maloney, are hard at work to address these longer-term forecasting challenges.

In a new paper in npj Climate and Atmospheric Science, the CSU researchers describe a breakthrough in making accurate predictions of weather weeks ahead. They’ve created an empirical model fed by careful analysis of 37 years of historical weather data. Their model centers on the relationship between two well-known global weather patterns: the Madden-Julian Oscillation and the quasi-biennial oscillation.

According to the study, led by former graduate researcher Bryan Mundhenk, the model, using both these phenomena, allows skillful prediction of the behavior of major rain storms, called atmospheric rivers, three and up to five weeks in advance.

Kai-Chih Tseng interview: Global rainfall pattern could extend predictions by 3 weeks

Earth’s atmosphere is chaotic, making it difficult for forecasters to predict weather more than 10-13 days in advance. However, research has increasingly shown that large-scale patterns of variability and relationships between states of the atmosphere in two faraway locations, called “teleconnections,” can help extend prediction skill beyond this limit.

“Few researchers have applied this mechanism to weather prediction,” said Kai-Chih Tseng, atmospheric science graduate student at Colorado State University (CSU). “Especially from two weeks to three months, which has been known as a ‘prediction desert’ in the past.”

A new study led by Tseng says that teleconnections with certain phases of a recurring tropical rainfall pattern could extend predictions up to 20-25 days in advance. The study is co-authored by Assistant Professor Libby Barnes and Professor Eric Maloney, both in CSU’s Department of Atmospheric Science.

The authors’ findings provide guidance on which tropical conditions might lead to improved forecasts beyond our current capability – and more time to prepare for extreme events.

As stated on the AMS web page listing the 2018 award winners, van den Heever was honored “for enduring passion for teaching and mentoring, for engaging students both inside and outside the classroom, and for unrelenting dedication to training future scientists.”

Burt is a research scientist with Prof. David Randall and the Education and Diversity Manager for the Department of Atmospheric Science and the Walter Scott, Jr. College of Engineering. She coordinates ESMEI’s (Earth System Modeling and Education Institute) Research Experiences for Undergraduates (REU) and the Front Range Teen Science Café programs. She earned her Ph.D. in Atmospheric Science from CSU in 2016.

According to the selection panel, Burt’s “work across a variety of AMS boards and committees, as a manager for education and diversity at CMMAP, and administration of an REU program, are just small parts of her already-large-and-growing involvement in our field. She has accomplished all of these things even while completing her doctorate at a top university, which clearly demonstrates, as one of the supporting letters said, ‘Dr. Burt really integrates all the aspects of excellence’ — research, mentoring, education, and service.”
