Flight Mission Details

Took measurements in and around an aerosol layer above stratus cloud; BRDF measurement above uniform stratus cloud.

Flight Path, Timing, and Measurements

Data recording for the CAR started at scan 200. Skies were mostly overcast with a stratocumulus layer, and an altocumulus layer above that . Weather at the surface was occasionally rainy at Barrow.

The first set of measurements were made around an aerosol layer above the stratus layer over sea ice, some distance from Barrow. The flight plan started under a hole in the stratus layer and continued above and below the aerosol layer to form a large vertically aligned loop through and around the aerosol. When above the aerosol layer the CAR was set to look down at the layer, and when below the aerosol or the cloud layer the CAR was set to position 4 (zenith) to examine the layers .

The aircraft then returned to Barrow, flying through the aerosol layer, during which the CAR scanned downwards. On return a number of straight line runs were made above the cloud layers over Barrow. This was followed by another loop through an aerosol layer, and a BRDF measurement over the uniform stratus cloud. During this measurement the surface could not be seen through the cloud and the roll angle varied from 17-20 °.

TABLE

Following this the aircraft flew a straight line leg under the stratus cloud and landed.
