Cindy Combs

Research Associate IV
Fort Collins, Colorado
Regional and Mesoscale Meteorology Branch (RAMMB)


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.
