Bio - Charles Morris
Charles came to work at the Jet Propulsion Laboratory in 1984 having
previously worked as an environmental consultant. With a background in
astrophysics (Michigan State University) and atmospheric science (Purdue
University), he actually works on instruments that look down at the Earth.
His first assignment was with the NASA Ocean Data System (now called
the Physical Oceanography Distributed Active Archive System) developing
software to produce sea ice maps from an instrument called the Special
Sensor Microwave Imager (SSM/I) which is flown on a defense department
More recently,Charles has been involved in the calibration and verification
of a number of spaceborne instruments. These include TOPEX/Poseidon (launched
1992), which measures sea level, NSCAT (launched 1996), which measured
winds over the ocean, and most recently, the Shuttle Radar Topography
Mission (SRTM), which flew on the shuttle in February 2000.
His research includes developing methodology for estimating lake levels
using data from spaceborne altimeters. Charles has also been involved
with research on comets. He maintains The Comet Observation Home Page
includes information and images on recent comets. Charles has observed
over 200 comet apparitions and is an expert on cometary brightness.
In 1988, asteroid 3783 was named "Morris" in honor of his work on comets.
