Cynthia Combs received a BS in Earth Science/Meteorology concentration from Central Michigan University (1985) and a MS in Atmospheric Science from Colorado State University (1987). She worked at STC-Metsat in Fort Collins, CO from 1988 to 1994 as a scientific programmer processing satellite and ground data on a variety of projects, including the CHANCES satellite cloud climatology, battlefield meteorology, cloud and smoke detection over the 1988 Yellowstone fires, and the NVAP water vapor database. She started at CIRA in 1992 as a research associate, and has worked a variety of projects since. She helped develop techiques to detect cloud liquid water over land using microwave satellite data from SSMI. Later work with microwave data includes identifying and examing RFI in Windsat data over US and analyzing soil moisture measurements from different ground instruments for use in satellite calibration. She has also continued her work with satellite cloud climatologies. An ongoing project now has over ten years of GOES satellite data quality-controled and archived over the continental US, and has completed and currently working on smaller projects focused on local forecasting conditions for National Weather Service offices in Wakefield, VA, Cheyenne, WY, Monterey, CA, and Eureka, CA. She has also done small programming and data processing jobs for several research scientists and have aided Master level students on their research projects, including cloud icing and soil moisture measurement from Windsat. Currently, she is aiding Steve Miller in his NPOESS low light sensor work and working with NASA to grid up Cloudsat data for Giovanni system.

Dr. Randy Chase

Job Titles:
  • Research Scientist
  • Global Cloud Retrieval Scientist ( Research Scientist I )
My name is Randy Chase, a Research Scientist working at CSU/CIRA. I grew up in Buffalo, New York where lake effect snow likely inspired my love of the weather. For my undergraduate degree I attended SUNY Brockport and had my first research experience at an REU hosted by Penn State where I worked with Dr. Jose Fuentes on ozone transport caused by convection in the Amazon Rainforest. After undergrad, I went to the University of Illinois at Urbana-Champaign where I got my M.S. and Ph.D. in Atmospheric Sciences working with Dr. Stephen Nesbitt and Dr. Greg McFarquhar. My graduate research focused on radar remote sensing of snow, where I investigated why the Global Precipitation Measurement (GPM) mission's snowfall retrievals were deficient, provided an alternative retrieval method and evaluated the new retrieval against CloudSat. After my Ph.D. I did a two year postdoc with Dr. Amy McGovern at the University of Oklahoma as part of the NSF AI Institute for Research on Trustworthy AI in Weather, Climate, and Coastal Oceanography (AI2ES). During my postdoc I was first tasked to write two plain language machine learning tutorials for meteorologists. Beyond the tutorials, I also investigated if machine learning could help us retrieve storm updrafts from ground based radar data alone. My role at CSU/CIRA, is to assist in two major projects: INvestigation of Convective UpdraftS (INCUS) and Satellite-based 3D global cloud field analysis (OVERCAST). I will leverage my expertise in radar remote sensing and machine learning to assist the projects in their respective goals.

Dr. Renate Brummer

Job Titles:
  • Acting Deputy Director, Senior Research Associate
Renate Brummer received the equivalent of a MS in Mathematics and Physics from the Universität München, Munich, Germany in 1981 and a PhD in Meteorology and Physical Oceanography from the University of Miami, Florida in 1986. Her areas of interest include mesoscale forecast modeling, satellite meteorology, and environmental education/outreach. She has been a CIRA employee since 1995 and has been working as project manager for different CIRA projects. During those years she managed the systems development team for the international school program GLOBE. The GLOBE Program is a worldwide community of students, teachers, scientists, and citizens working together to better understand, sustain, and improve Earth's environment at local, regional, and global scales. She also managed the so-called FX-Net project, a meteorological forecaster workstation which provides the user interface and functionality of the AWIPS workstation (used by NWS forecasters) via the internet. During the last two years, Renate worked as a project coordinator for CIRA's Regional and Mesoscale Meteorology Branch (RAMMB).

His dissertation focused on using atmospheric motion vectors to depict flow fields over deep convection observed from super-rapid scan geostationary satellite imagery, and how they could be used to identify signals relevant to severe weather forecasting. He currently works on developing and implementing dense-optical flow derivation algorithms for a variety of satellite meteorology-related applications.
