The Web-enabled Landsat Data (WELD) project is systematically generating 30m composited Landsat Enhanced Thematic Mapper Plus (ETM+) mosaics of the conterminous United States and Alaska from 2005 to 2012. The WELD products are developed specifically to provide consistent data that can be used to derive land cover as well as geophysical and biophysical products for regional assessment of surface dynamics and to study Earth system functioning. The WELD data are now available from the Oak Ridge National Laboratory’s Distributed Active Archive Center for Biogeochemical Dynamics (in addition to the USGS WELD site).
