Paul DeMott’s paper published in Proceedings of the National Academy of Sciences
All over the planet, every day, oceans send plumes of sea spray into the atmosphere. Beyond the poetry of crashing ocean waves, this salt- and carbon-rich spray also has a dramatic effect on cloud formation and duration.
Yes, clouds, which cover 60 percent of the Earth’s surface at any given time. In a new study, “Sea spray aerosol as a unique source of ice nucleating particles,” published in Proceedings of the National Academy of Sciences, online Dec. 21, Colorado State University’s Paul DeMott, a senior research scientist in the Department of Atmospheric Science, says sea spray is a unique, underappreciated source of what are called ice nucleating particles – microscopic bits that make their way into clouds and initiate the formation of ice, and in turn affect the composition and duration of clouds.
“The presence of these particles is critically important for precipitation and the lifetime of clouds, and consequently, for their radiative properties,” said DeMott, who works in the lab of Sonia Kreidenweis, professor of atmospheric science, associate dean for research in the College of Engineering and a University Distinguished Professor.

SEA-POL: Advanced ship-based radar for open-ocean atmospheric research
Directed by Department of Atmospheric Science Professor Steven Rutledge (Principal Investigator) and Department of Electrical and Computer Engineering Professor V. “Chandra” Chandrasekar (Co-Principal Investigator), this $1.3 million award from the National Science Foundation will develop an advanced ship-based radar to study clouds and precipitation over the oceans. This state-of-the-art polarimetric Doppler radar is known as SEA-POL, and it employs dual-polarization technology, where both horizontal and vertically polarized radar signals are transmitted and received by the radar. This technology was pioneered at the university’s CSU-CHILL National Radar Facility, also directed by Professor Rutledge. The polarization technology improves rainfall estimation and provides information on the distribution of liquid and ice particles in clouds. This information, which is vital to improving understanding of the global water cycle, air-sea interaction, and validating computer models of global precipitation, is the same technology used on the national radar network to detect severe weather.
SEA-POL will be deployed periodically on U.S.-operated world-class research ships on several monthlong cruises to various areas of the world’s oceans. With seventy-five percent of the world’s rainfall occurring over oceans, studying oceanic storms and measuring rainfall they produce with SEA-POL will allow scientists to better understand how tropical clouds and storms contribute to climate change. When SEA-POL is not deployed at sea, it will operate at Colorado State University for research and education.

AMS President Alexander MacDonald will speak at FORTCAST chapter meeting
2015 American Meteorological Society (AMS) President Alexander (Sandy) MacDonald will speak at the upcoming FORT Collins Atmospheric ScientisTs (FORTCAST) local chapter meeting. Sandy will give a talk on “Science as our Protector.” The next chapter meeting is scheduled for Thursday, Oct. 8 at 6:30 p.m. in room 107 of the Behavioral Sciences Building on CSU’s main campus. This event is free and open to the public. Food and beverages will be provided.
Who: Sandy MacDonald, 2015 AMS President
What: “Science as our Protector”
When: Thursday, Oct. 8 at 6:30 p.m.
Where: Room 107 at the Behavioral Sciences Building at Colorado State University
Please RSVP if possible. Visit FORTCAST’s website for more details.
Abstract: Science is not a passive bystander in our lives. It is our protector through the generations. I illustrate this talk with examples of the role of science as it has affected six generations of my own family. Our science protects people in many ways, from forecasting floods and hurricanes, to determining the threat of anthropogenic climate change. I will give examples of some of the possible environmental catastrophes of the 21st century, and how Earth system science could lead to favorable outcomes – or not. We have been given powerful tools; global observing, advanced computing and models, profound understanding of how the Earth system works. Success is not a given – it depends on how effective we are in science, technology, and the larger political sphere.

Christina McCluskey awarded ASCENT travel grant
The CSU Department of Atmospheric Science ASCENT (Assisting Students, Cultivating Excellence, Nurturing Talent) program was initiated in fall 2014 to help enrich the graduate experiences of our many talented students. One component of ASCENT is an international travel grant program that allows students to pursue opportunities for research enrichment activities outside the U.S.
This year Ph.D. candidate Christina McCluskey, who is advised by University Distinguished Professor Sonia Kreidenweis, was selected as one of the students to receive this award. Christina traveled to Carna, Ireland in August 2015 to participate in a research study conducted at Mace Head Atmospheric Research with the BACCHUS (Impact of Biogenic versus Anthropogenic emissions on Clouds and Climate: towards a Holistic UnderStanding) European collaborative project. The main goal of the field study was to measure ambient aerosol to determine the influences of oceanic phytoplankton blooms on sea spray aerosol properties and abundances. During this study Christina monitored concentrations of ice nucleating particles, atmospheric particles that initiate heterogeneous ice formation in clouds. The data from this study will advance the understanding of how mixed phase clouds in oceanic and coastal regions might be influenced by ice nucleating particles associated with sea spray aerosol.

James Ruppert receives 1st place at 2015 AMS Conference on Meso Processes
Congratulations summer 2015 Ph.D. graduate James Ruppert, advised by Professor Richard Johnson, for receiving first place for his oral presentation, “The diurnal cycle and Large-scale Tropical Climate,” at the 2015 American Meteorological Society 15th Conference on Meso Processes. The objective of the study aimed to understand how the diurnal cycle fits into the greater climate system. The questions James asked are: How well do we model the diurnal cycle (on a global scale)? Can we neglect the diurnal cycle as a physical process? Can we get it wrong in climate models without consequences? James is now in search of answers to these questions during his postdoctoral fellowship at the Max Planck Institute for Meteorology (MPI-M).
Congrats, James! Good luck with your continued research at MPI-M.

Plains Elevated Convection at Night (PECAN) Field Campaign
CSU Department of Atmospheric Science Assistant Professor Russ Schumacher and several graduate students will be taking part in the Plains Elevated Convection at Night (PECAN) field campaign from June 1 to July 15. This project aims to observe and better understand the thunderstorms that often form over the central U.S. at night. These storms produce much of the rainfall that is critical for agriculture in this region but also can lead to hazardous weather in the way of severe winds, hail and flash flooding.
The project involves scientists from eight research laboratories and 14 universities, with a wide array of radars, research aircraft and atmospheric profiling instruments that will take on the task of observing convection after dark. The CSU team will be collecting mobile radiosonde observations during the field phase of the project, and will seek to better understand the processes that govern the organization, motion and rainfall production in nocturnal convective systems. For more, here’s an overview of PECAN from the National Science Foundation.

Physics Today features article by M.S. 2014 graduate Annareli Morales
M.S. 2014 graduate Annareli Morales’ M.S. research, “Cyclonic circulation development during extreme precipitation,” is featured in the April 21 Daily Edition, Down to Earth section of Physics Today. Annareli, a December 2014 graduate co-advised by Assistant Professor Russ Schumacher and Professor Sonia Kreidenweis, explored the impact of latent heating on the development of a mesoscale vortex observed near Boulder during the September 2013 Colorado floods. Her simulations and sensitivity studies suggest that the vortex was responsible for the increased rain rates that led to significant flooding in Boulder. Understanding the mechanisms involved with these phenomena will help improve their forecasting and their impact on public safety.

Aaron Piña receives 2nd place at 2015 AMS conference on Atmospheric Chemistry
Congratulations to Ph.D. student Aaron Piña for receiving second place for his oral presentaion at the 2015 American Meteorological Society 17th Conference on Atmospheric Chemistry. Reactive nitrogen from cattle feedlots in eastern Colorado is reaching pristine alpine lakes in Rocky Mountain National Park, leading to undesirable ecosystem changes. Aaron’s presentation, “Prediction System for Nitrogen Deposition in Rocky Mountain National Park,” discussed the development of an early warning system, which utilizes output from Russ Schumacher’s operational WRF runs. The early warning system allows feedlot producers to temporarily alter management practices that reduce nitrogen emissions. More information on the early warning system can be found on the Rocky Mountain National Park Early Warning System website.

Leah Grant and Renee Duff receive 2015 AMS awards
Congratulations to Ph.D. student Leah Grant and 2014 summer CMMAP intern Renee Duff for their awards at the 95th AMS Annual Meeting in Phoenix. Leah and Renee investigated the impact of enhanced aerosol concentrations, such as would be associated with pyrocumulus clouds forming over active fires, on the microphysical characteristics of an idealized pyrocumulus cloud simulated with RAMS. They then used the microphysics information to infer possible electrification mechanisms for pyrocumulus convection.
Leah received an Outstanding Student Presentation Award for her talk at the Aerosol-Cloud-Climate Interactions Symposium: “Aerosol-induced microphysical processes and electrification in pyrocumulus.”
Renee won Best Student Poster at the AMS Student Conference: “Wildfire Pollution and its Effects on the Microphysical and Electrical Properties of Pyrocumulus.”

David Henderson and Veljko Petkovic receive AMS Outstanding Student Presentation awards
Congratulations to Professor Chris Kummerow’s Ph.D. students David Henderson and Veljko Petkovic for each receiving the Outstanding Student Presentation: Joint Satellite Program award at the 95th Annual Meeting of the American Meteorological Society held in Phoenix. Presentations focused on describing new concepts, research, operations and practical application of satellite measurements for analyzing and predicting the weather, the ocean, the climate, and the environment.
David’s research, “Investigating the Effect of ENSO Upon Oceanic Rainfall Estimates,” describes how anomalous shifts in passive oceanic rainfall intensity are linked to the level of organization in oceanic precipitating systems. Receiving this oral presentation award was especially gratifying for David, as he also won for the same topic, except in poster form, at the WCRP and EUMETSAT Climate Symposium in Darmstadt, Germany in October.
Veljko’s research, “Improving the Quality of Extreme Precipitation Estimates Using Satellite Passive Microwave Rainfall Retrievals,” looks for a deeper understanding of the influence of environmental conditions on defining the ice-to-rain ratio that provides a foundation for addressing biases seen in passive microwave rainfall retrievals globally. The department has no doubt that future awards for Veljko’s research, like David’s, are right around the corner as well, as Veljko was honored earlier in 2014 with a NASA Earth and Space Science Fellowship (NESSF).
