| Description: | A low-resolution (300 m) MPL system (unit number 04) was installed at the
SGP site in April '97 upon the laser diode failure of the 02 unit in
March. Calibration of this instrument in August found that the optics
were misaligned causing a near range focusing error in the data.
Calibration files produced for this data, while acceptable, do not
completely correct for the problem. As a result, aerosol property
retrievals using this data are not suggested. Cloud boundary heights,
though appear satisfactory. This system was removed from SGP in early
September |
