Retrieval of cloud optical thickness and effective droplet radius are made on a
uniform stratus deck in the vicinity of Santa Maria during an overpass of
NOAA-12 on 12 June 1992. The remote technique makes use of atmospheric optical
depths derived from instrumentation aboard the NASA ER-2 and NCAR Electra to
correct for the atmosphere above cloud top. Concurrent hemispheric
transmission measurements from the Electra and from the ground on Santa Maria,
along with bidirectional transmission measurements on the ground are used to
retrieve optical thickness and compared with the satellite derived results. In
situ microphysical data collected on the University of Washington C-131 is
compared with the inferred results.
