HIRAD - GRIP Browse Images v.0 All images are excess T B in units of Kelvin at 5 GHz Excess T B is HIRAD observed T B, minus calculated T B for calm, no-rain ocean surface at the given off-nadir angle. It is preferred in order to eliminate the incidence angle effect, thus enabling easier identification of geophysical features in the data. HIRAD observed 5 GHz T B is included in the provided datasets but not plotted here Brightness temperatures for other frequencies and subsequent geophysical retrievals are still being developed at the time of this release (9 Sept 2011) HIRAD flights for Earl (1-2 Sept) and Karl (16 Sept) are processed Datasets are provided in Matlab and NETCDF formats and include all necessary information such as time and geographic location of each observation Earl images are plotted out to +/- 70 degrees from nadir Karl images are plotted out to +/- 65 degrees from nadir Legs plotted here and provided in the datasets are for straight and level flight, as determined by constant true heading of the aircraft. Along-track striping on some swaths is indicative of unresolved calibration issues. This feature is eliminated in the directory filtered
