Below are quick-look images from yesterday’s first science flights (June 7). A single polarization each of the radiometer and radar are shown. The data are from high-altitude lines 3 through 8 (lines 1 and 2 were not acquired). For reference, the study site map is also shown (at right).
The radiometer brightness temperature (Tb) and normalized radar cross-section (sigma-0) images are uncalibrated – default parameters were used to convert instrument counts to the respective Tb and sigma-0 quantities. No external calibration has been done at this stage using the lake reference data, however the lake data were used to check that the data levels were approximately correct.
