What are the different release numbers of GLAS data?
Changes in input data and algorithms result in a new release number, set by the GLAS Software Development Team. Products generated with a new release may be processed forward in time or reprocessed from earlier data. If reprocessed, NSIDC either deletes or hides data granules from previous releases, once they have been replaced by the current release. The first data release was Release-12; there were no additional products with release numbers less than 12. For a complete list of the current data release, see the Current Release Schedule Web page. For a complete list of past data releases, see the Past Release Schedule Web page.
