Professional Employment History
From 1976-78 Dr. Welch was a Research Associate in the Department
of Atmospheric Sciences, Colorado State University, and from 1978-81
he was a Research Associate in the Institute fur Meteorologie,
Johannes Gutenberg Universitat in Mainz, Germany. During
1981-82, he was an Associate Professor in the Department of Geophysical
Sciences at Old Dominion University in Norfolk, Virginia. In
July 1982, Dr. Welch assumed the position of Head, Data Acquisition
and Analysis Group, Institute ofAtmospheric Sciences, at South
Dakota School of Mines and Technology (SDSMT) and Associate Professor
in the Department of Meteorology. In 1987, he was promoted
to the position of Senior Scientist and in 1990 to the position
of Professor. During 1989-90, he was UCAR Visiting Scientist
at he Naval Oceanographic and Atmospheric Research Laboratory in
Monterey, California. In 1992, he was appointed Director
of the Center for Robotics, Artificial Intelligence and Remote
Sensing at SDSMT. In 1997, Dr. Welch assumed the position
as Chair, Department of Atmospheric Science, at the University
of Alabama in Huntsville.
Dr. Welch has held membership in the American Meteorological Society,
American Geophysical Union, American Physical Society, American
Association for the Advancement of Science, New York Academy of
Sciences, and the Society of Sigma Xi. He serves as a science
team member on the ASTER and CERES as part of the NASA Earth Observing
System (EOS) and the European SCARAB, IASI and POLDER science teams. He
has served on the EOSDIS Scientific Advisory Panel, as Co-Chair
of the Langley DAAC Scientific Advisory Panel, the AMS Radiation
Committee and the AMS Committee on Artificial Intelligence Applications
to Environmental Science.
Current Research Activities
Dr. Welch has authored more than 80 peer-reviewed publications
and a greater number of conference papers. Research areas
include: 1) remote sensing of aerosol and cloud properties 2) development
of global satellite cloud masks, 3) Earth radiative budget studies
and retrieval of surface fluxes 4) characterization of global ecosystems
and land-use changes 5) 3-D radiative transfer modeling of cloud
fields 6) remote sensing applications of infectious disease outbreaks.
