Version 1.1 of the MODIS Mosaic of Antarctica 2003-2004 (MOA2004) Image Map Now Available

The Antarctic Glaciological Data Center (AGDC) at NSIDC is pleased to announce the release of Version 1.1 of the MODIS Mosaic of Antarctica 2003-2004 Image Map. In version 1.1, the original grain size image file, moa750_r1_nds.img.gz, was replaced with several new grain size image files with better resolution, and file names were changed to reflect the year for the data acquisition. The MOA2004 Image Map consists of two cloud-free digital image maps that show mean surface morphology and a quantatative measure of optical snow grain size on the Antarctic continent and surrounding islands using 260 orbit swaths from the Moderate Resolution Imaging Spectroradiometer (MODIS) instruments on board the NASA EOS Aqua and Terra satellites.
