Abstract
Vertical temperature and moisture profiles from the
Ground-Based High-Resolution Interferometer Sounder (GB-HIS)
are studied for the coastal marine atmosphere. In May of 1991
and 1992 the GB-HIS instrument was operated on the Research
Vessel Point Sur during a cruise off the central California
coast. The ability of the GB-HIS retrieval algorithm to
produce accurate temperature and moisture profiles is
evaluated using Root Mean Square (RMS) difference, Bias, and
Explained Variance statistics. In addition, objective
analysis is performed on timesections of temperature and
moisture. Temperature retrievals, on average, attained
significant skill throughout the low troposphere. Moisture
retrievals attained moderate skill in the lower and upper
boundary layer, but no skill in the mid-boundary layer due to
non-depiction of small scale moisture features. Results
showed a maximum RMS temperature difference of < 3 °C and RMS
dewpoint difference of < 12 °C in the low troposphere (up to
700 mb) over both cruises. Preliminary analysis of the updated retrieval algorithm is performed and further
improvements are discussed.
