Gbrowse Low Resolution Products
GBROWSE is a gridded browse product (an extension of the SADIST-1 BROWSE product). The product contains gridded sub-sampled, calibrated brightness temperature or reflectance images from some or all of the ATSR-1/ATSR-2 detectors. The product optionally includes the results of cloud-clearing/land flagging.
Ungridded products contain pixels in the ATSR scan geometry. There is a correspondence between the contents of a record and the contents of an ATSR instrument scan.
Gridded products contain 512 x 512 pixel images. The correspondence between pixel and the ATSR instrument scan from which it came has been lost. Nadir and forward view pixels are collocated, and have been regridded onto a 1km grid.
