Refer to Reichenbach et. Schowengerdt 1987 provides more information about modulation transfer functions, point-spread function, and pixel sampling. Observations are not available. The red outline in the Southern Hemisphere image illustrates coverage of a single scene. Temporal coverage begins 1 April 1992 for the Southern Hemisphere and 1 August 1993 for the Northern Hemisphere.
Data continue through present.
A summary of data quality, cloud cover, and initial estimates of albedo and surface temperature accompany each browse image. The procedure selects every fourth pixel in every fourth line from bands 2 and 4, and divides the raw sensor value of those pixels by four. The single-band components of the browse images are 512 pixels wide and vary in length between approximately 300 and 1300 lines. Coastlines, major political boundaries, and major rivers are overlain on the browse images with a data value of 255 for the band 2 browse images and 0 for the band 4 browse images. Tools to extract and display HDF images are available from the NCSA Web site .
