NASA Responds To FOIA Request

NASA has responded to my FOIA Request. To recap, I requested two items from NASA: 1) the height in the atmosphere scanned by each footprint for each scan of the Aqua satellite, and 2) the Ai and Theta Bar i used by NASA to calculate the synthetic values for Aqua's channel 4.

Their response was that there are no records for the height of the footprint scans on the Aqua satellite and that the values for Ai and Theta Bar i are as follows:

A(i) = 0.38648412E-1, -0.13865858, 0.60949275, 0., 2.0037199, -0.95993573, 0., 0.28063577, -0.9307997E-1, 0.37032401E-1, -0.15795620E-2, -0.49943969E-2, -0.11815043E-1, 0.70557197E-1, -0.33432437E-1

thetabar(i) = A_mean(i) * amsu_noise_tr(i) where:

A_mean(i) = 1200.2806, 901.08093, 949.21509, 0., 1242.5841, 1382.2343, 0., 1359.1735, 1323.4860, 975.67328, 920.14246, 654.80048, 499.30478, 313.854318, 1955.0244

amsu_noise_tr(i) = 0.17, 0.22, 0.25, 0.14, 0.20, 0.17, 0.14, 0.16, 0.16, 0.22, 0.24, 0.35, 0.48, 0.80, 0.12


Notice that each of these collections of numbers contains 15 numbers. These correspond to the 15 channels on the Aqua satellite.

I still need to check that the above values, when used in NASA's formula for creating synthetic channel 4 data, actually produce the published values for that channel.

I'm out of ideas on how to obtain the height in the atmosphere each footprint scans.
