Grids represent spatially interpolated data.
The interpolation technique maximizes the radiometric integrity of original brightness temperature values, maintains high spatial and temporal precision, and involves no averaging of original swath data. Resolution is 25 km for all channels and 12.5 km for the 85 GHz channels. Users can also request the complete data set or a long time series of data.
