Kimberly Casey, Ph.D.

Kimberly Casey is a scientist in the National Land Imaging Program at the U.S. Geological Survey Headquarters.  Dr. Casey's research focuses on high spectral resolution investigations of Earth's cryospheric, land, ocean and atmospheric processes.   Dr. Casey also serves as the Earth Observation capabilities lead within the National Land Imaging Program.


Dr. Casey conducts high spectral resolution research investigations of cryospheric, land, ocean and atmospheric processes. She has particular interest in radiative characterization, biogeochemical cycling, and investigation of pollutant, biota, black carbon, dust and debris geology and geochemistry in the cryosphere via remotely sensed and in situ measurements. These studies aid in the understanding of particulate provenance, cycling and radiative impacts. She is adept in use of remote sensing observations to map ice radiance, stratigraphy, geochemistry, and atmospheric influences and works to quantify and differentiate sensor performance and detection of change over time.  She has experience in analytical chemistry techniques, including ice core and surface ice composition characterization, aquatic and tree core digestion analysis. Her field experience includes sampling on glaciers, ice core planning, retrieval, and analysis, and ground penetrating radar acquisition. She has conducted field work and led observation campaigns at glaciers and ice sheets on all 7 continents on Earth.  

Dr. Casey also aides in the National Land Imaging requirements, analysis and capabilities branch providing Earth Observation capability leadership support toward internal, Federal and international sensor programs, initiatives and tasks.  She oversees an Earth Observation sensor capability working group, and the publication of the annual Earth Observation sensor compendium and related living database. Dr. Casey serves as the USGS lead for the World Meteorological Organization's international Polar Space Task Group and their High Mountain Summit initiative.  Dr. Casey was involved with the NASA Plankton, Aerosol, Cloud ocean Ecosystem (PACE) Mission initial science team and in situ data identification and recording efforts and takes part in the NASA Surface Biology and Geology Mission algorithm, calibration/validation and applications working groups.
