The CAR multi-wavelength radiometer, scanning from zenith to nadir aboard the Convair C-131A, was used to measure surface reflectivities. From 1 September to 4 September (UW Flights 1697 to 1699) and from 13 September to 20 September (UW Flights 1706 to 1716), the CAR was mounted so that it scanned approximately from horizon-to-horizon, thereby providing measurements similar, in principle, to a scanning radiometer aboard a satellite.
UW Flight No | Date (1995) | Period of Measurements (hhmm UTC) |
Location | Type of surface | Comments |
---|---|---|---|---|---|
1689 | 18 Aug | 1850 - 1907 | N of Brasilia | Cerrado | 4-5 banked circles then 1 circle for sky reflectivities. (See Hobbs' photos of surface on Roll #1 photos #8-11.) |
1692 | 24 Aug | 1552 - 1924 | N of Cuiaba | (Smoke) | Measurements over, in, and under smoke |
1693 | 25 Aug | 1905 - 2001 | W and N of Cuiaba | Uniform forest | Surface reflectivity measurements. (See Hobbs' photos on Roll #2 photos #10-11 and #13-15.) |
1701 | 6 Sep | 1337 - 1414 | NE of Porto Velho | Dense forest below | Measurements above smoke, also sky radiance measurements. |
1703 | 7 Sep | 1809 - 1840 | Reservoir at Repressa Samuel | Dark water plus marshy ground | CAR pointing down and then up at sky. (See Hobbs' Roll 4 photo #24 and Roll 5 photo #1 for shots of terrain.) |
1704 | 11 Sep | ~1407 - 1425 | SE of Porto Velho | (Smoke) | CAR pointed down onto uniform smoke layer |
1709 | 14 Sep | 2013 - 2241 | Between Santarem and Maraba | (Smoke) | CAR pointing down onto very thin smoke layer at ~4500 ft. Good lidar profile. |
