Jeff’s research is in the area of polar climatology and atmospheric
remote sensing. He is interested primarily in the radiative effects of
clouds on the surface energy balance, and has developed algorithms and
models for use in the retrieval of cloud properties and radiative fluxes
from optical satellite data. Current research topics include the spatial
and temporal variability of polar cloud, surface, and radiation
properties, satellite-derived polar winds, and recent climate
trends.

Jeffrey R. Key is the is the Branch
Chief of the Advanced Satellite Products Branch, co-located with the
Cooperative Institute for Meteorological Satellite Studies at the
University of Wisconsin-Madison. Jeff received the B.S. degree from
Northern Michigan University in 1977, the M.S. from NMU in 1982, and
the Ph.D. from the University of Colorado-Boulder in 1988. He worked
as a research scientist at the University of Colorado for many years,
and held faculty positions at the University of Alaska-Anchorage and
Boston University before joining NOAA in 1999.
