Who we are

Hello and welcome to the homepage of Professor Sue van den Heever's research group. Our research focuses on cloud processes, specifically the microphysical and dynamical characteristics of deep convective cloud systems, aerosol-cloud feedbacks, convective organization and the representation of these processes in numerical models. More detailed information on the scientific questions we are currently addressing can be found on our research webpage and from our publications. We utilize numerical models to achieve our scientific goals, in particular the open source Regional Atmospheric Modeling System (RAMS) that is developed and maintained by the van den Heever research group. We also draw on satellite and radar observtions in our research, and numerous members of our research group have participated in a number of field campaigns. Our group, together with students from the Schumacher, Schubert, Rasmussen and Rutledge groups, recently completed C3LOUD-Ex, a field campaign to investigate updraft and cold pool characteristics of convective storms over NE Colorado. The field campaign utilized drones, radiosondes and radar data from the CSU-CHILL facility to address the campaign science goals and was recently described in the Colorado State University Magazine and on SOURCE. Several of our group are currently participating in NASA's CAMP2Ex being conducted in the region of Philippines. Sue is serving as the P-3 flight scientist and dropsonde PI, and Sean and Alex are responsible for dropping the dropsondes and are also assisting with flight planning. See Recent News below for regular updates and photos of the campaign which runs through 6 October 2019.

2019

August 31: CAMP2Ex, the field campaign that Alex and Sean are currently deployed on, has been written up on the NASA website and in the Manila Bulletin. Sue is quoted in both articles.

August 19: Alex and Sean depart Colorado for the Philippines to participate in the CAMP2Ex Field Campaign. Sean and Alex will spend the next 7 weeks at Clark International Airport on the island of Luzon in the Philippines flying and dropping dropsondes from the NASA P-3 aircraft and forecasting for the mission. The CAMP2Ex project is designed primarily to examine the impacts of aerosol on clouds and precipitation, and more can be read about the CAMP2Ex campaign here.

August 15: Nick Falk joins our group as a new MS student. Nick comes to us from UC Davis, where he received his BS. Welcome Nick!

August 1: Congratulations to Peter who won the First Place Poster award at the 2019 AMS Mesoscale conference. Peter's poster, titled "The Impacts of Aerosol Particles on Deep Convective Clouds - a Multimodel Assessment", described some of the research he has been conducting as part of the Aerosol, Cloud, Precipitation, and Climate (ACPC) working group.

August 1: Welcome to Bowen Pan, who joins our group as a Postdoctoral fellow. She joins us from Texas A&M, where she recently finished her PhD under the advisement of Renyi Zhang.

July 29-August 2: Jennie, Leah, Minnie, and Peter present at the 2019 AMS Mesoscale conference in Savannah, GA.

July 15-19: Jennie Attends the 2019 Department of Energy Aerosol Summer School at the Pacific Northwest National Laboratory in Richland, WA.

June 19: Nick Falk, an incoming MS student who will join us in the fall, is awarded the CSU College of Engineering Walter Scott, Jr. Fellowship. Congratulations Nick!

June 18: Congratulations to Jennie who was funded to attend the 2019 Department of Energy Aerosol Summer School. At this workshop, held at the Pacfic Northwest National Laboratory in Richland, WA over 5 days, Jennie will learn about the state of the science in aerosol formation, characterization, observations, and modeling. More information can be found about the workshop at their website.

June 12: Sean is awarded the NSF Graduate Research Opportunities Worldwide travel award. With this award, Sean will travel to Delft Technical University in the Netherlands next spring for three months to work with Prof. Pier Siebesma. While in Delft, Sean and Prof. Siebesma will work on a project investigating mixed-phase clouds with observations and numerical simulations. More information can be found on the department website. Congratulations Sean!

May 7-9: Aryeh, Emily, and Sue present at the US CLIVAR Workshop in Boulder, CO.

April 24: Jennie, Kristen, and Sean volunteer at the Colorado Rockies Weather and Science Day 2019. The event, which had over 10,000 kids in attendance, was designed to encourage students in kindergarden through high school to consider careers in STEM. Our group's participation in the event was to showcase how we use drones to research the weather. On the day of the event, Sean flew one of our group's drones, funded by Sue's Monfort Professorship, around the infield while Jennie was interviewed by Steve Spangler on stage about the C3LOUD-Ex field campaign and how we use drones to collect data about storms. More information can be found on the SOURCE article.

April 23: Congratulations to Jennie who was funded to attend the AMS Summer Policy Colloquium! Jennie will get an intense experience learning about science policy and politics for ten days in Washington, DC this summer. While in DC, Jennie will meet with politicians, staffers, AMS staff, and more to advance her knowledge. More information can be found on the department website.

April 22-26: Peter and Sue present at the 2019 Aerosol, Cloud, Precipitation, and Climate Working Group (ACPC) meeting in Nanjing, China.

April 2: Congratulations to Peter who was awarded a CSU Graduate Student Council Travel Grant! Peter will be attending the 2019 Aerosol, Cloud, Precipitation, and Climate Working Group (ACPC) meeting in Nanjing, China from April 24-26. More information about ACPC and the upcomming conference can be found on their website.
