Preflight goals focused on characterizing aerosols and surface albedo at T2 in coordination with Terra and aerosols and BRDF over the Gulf in coordination with Aqua.
CAR problems at start; computer & inst out of sync. Maybe because of abnormal shutdown yesterday. Up & running after ~40 min. Usable data including clouds. Lots of BRDF meas over Gulf. Interesting cloud-aerosol contrast in SWIR vs visible channels. Normal shutdown.
1623: Engines on
1634: AATS darks
1649: AATS unparked, acquiring good sun data, some scat Ci
1658: No Ci for last few minutes
CAR not working
1715: Ci ahead
1736: Extensive Ci—turned around—10 nm before T2
Need to allow extra 10-15 min to T2 to get there on time
1827: NNE of VER positioning for spiral down & CAR runs over area
1832: Begin spiral down at 1500’/min.?
Desired low leg leading to RSP: 30 to 35
1848: Bottom of spiral at 250’ AOD(520)~0.16
1849: Begin CAR maneuvers
1900: Complete CAR maneuvers; descend to 250’
1904: Begin principal plane run at ZGPS~150’ (190450 UT) AOD(520)~0.157
1908: Begin spiral up to 8500’ ~ record 2320? Had to cut horiz leg short due to Ci ahead; spikes in AATS data during spiral due to tracking, not Ci
1915-1919: (We are ~20 min from VER) High alt (2.7 km, 8500’) horiz run back along princ plane heading ~194.
1924-1930: RSP perpendicular run; crossed at 192530 UT
1940: Land. AOD(520) at VER 0.18
1943: Engine off
