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 publications. We use numerical models to achieve our scientific goals, in particular the open source Regional Atmospheric Modeling System (RAMS) that is now developed and maintained by the van den Heever research group. We also utilize satellite and radar data to conduct 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.

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

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: Congratulations to Sean who was 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

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.

March 29: Jennie and Sean volunteer with a class visit from Altitude Elementary in the department, showcasing a drone and describing how we observe the weather and improve our scientific knowledge of the atmosphere with drones to over 100 second graders. A full writeup of the day can be found on the department website.

March 5-7: Sean and Sue present at the CAMP2Ex Science Team Meeting. The CAMP2Ex field campaign, scheduled to take place in August and September, is a NASA-sponsonred field campaign based out of the Philippine island of Luzon. The field campaign is designed to measure aerosol, cloud processes, and radiation from the NASA P-3 aircraft. During the field campaign, Alex and Sean will operate the dropsonde system aboard the P-3 aircraft and Sue will serve as a flight scientist, all spending substantial time in Luzon. More information can be found on the CAMP2Ex website.
