Techno-Archaeology Rescues Climate Data from Early Satellites, National Snow and Ice Data Center
Image: Forty-three years after the Nimbus II satellite collected these data, a team from NSIDC and NASA recovered a global image from September 23, 1966. In this view over Antarctica, overlaid on Google Earth, the Ross Ice Shelf appears clearly at left.
“Starting with the methods developed for the Lunar Orbiter Image Recovery Project (LOIRP) at NASA Ames Research Park, a team at NSIDC worked with Dennis Wingo at LOIRP to search NASA archives for the original Nimbus tapes containing raw images and calibrations. Their first goal was to read and reprocess the data at a higher resolution, removing errors resulting from the limits of the original processing.”
