Christa Peters-Lidard is an American hydrologist known for her work on integrating land surface modeling and data assimilation, particularly with remotely sensed measurements of precipitation.


Early life

Peters-Lidard grew up in Chesterfield County, Virginia where she was fascinated about nature, learned that she was good at math, and that she liked earth science. As an undergraduate at Virginia Tech she worked on a project on aquifers and groundwater flow at the
United States Geological Survey The United States Geological Survey (USGS), founded as the Geological Survey, is an agency of the U.S. Department of the Interior whose work spans the disciplines of biology, geography, geology, and hydrology. The agency was founded on Mar ...
and at that point she realized that she wanted to be an earth scientist at National Aeronautics and Space Agency (NASA).

Research

Peters-Lidard's graduate work linked rainfall measurements with data from airborne sensors detecting rainfall. She also established a mathematical framework to link land-atmosphere models with remotely-sensed rainfall data, and considered the role of heat being released from soils on modeling energy fluxes. While at Georgia Institute of Technology, she used balloons to make measurements of boundary layers in the atmosphere. Peters-Lidard has had one Ph.D. student, Feifei Pan, who estimated the amount of water in soils based on rainfall levels, and examined algorithms used to characterize variability in a region's topography. Peters-Lidard led the team that built a high performance computing cluster that became NASA's Land Information System software (LIS). LIS was the co-winner of NASA's 2005 software of the year award. LIS allows land surface modeling and data assimilation and, working with Sujay Kumar, Peters-Lidard used this system to quantify soil moisture assimilation.
