When Typhoon Lan made landfall in Japan on Oct. 22, the Global Precipitation Measurement mission core satellite or GPM analyzed the storm and added up the high rainfall that it generated.

In 2008, Deeter became the MOPITT project leader, where he has analyzed observations from a wide array of contemporary satellite instruments including MODIS, AIRS and AMSR-E. Deeter’s technical work on MOPITT primarily involves retrieval algorithm development and validation. His current goals for MOPITT retrieval algorithm development include: accounting for gradual long-term instrumental changes in the retrieval processing, thereby eliminating long-term ‘drift’ in the retrieval products, and fully exploiting MOPITT’s near-infrared channels as a path towards increasing the sensitivity of the retrieval products to CO in the boundary layer. He is the U.S. principal investigator for MOPITT, an instrument flying aboard NASA’s Terra spacecraft that measures the global distributions of carbon monoxide. By understanding the sources and behavior of carbon monoxide, scientists can also gain insights into a number of other pollutants. Deeter is a researcher in NCAR’s Atmospheric Chemistry Division.
