Basic Terra fusion product algorithm theoretical basis and data specifications

The basic Terra fusion product provides general atmospheric and surface research community a unique temporally-fused set of radiance measurements from all the Terra instruments, namely, the Moderate-resolution Imaging Spectroradiometer (MODIS), the Multi-angle Imaging SpectroRadiometer (MISR), the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), the Clouds and Earth’s Radiant Energy System (CERES), and the Measurements of Pollution in the Troposphere (MOPITT). This product contains (1) radiance values of IOFVs (pixels) for each spectral band at a native resolution for each instrument, (2) their quality flags associated with radiance values, (3) their latitude and longitude information at a native resolution, (4) time of observations, (5) instrument viewing geometry, and (6) solar position.NASA ACCESS program under contract NNX16AMO7AThis research is part of the Blue Waters sustained-petascale computing project, which is supported by the National Science Foundation (awards OCI-0725070 and ACI-1238993) and the state of Illinois. Blue Waters is a joint effort of the University of Illinois at Urbana-Champaign and its National Center for Supercomputing Applications.The computations for this research also used the NSF-supported ROGER (Resourcing Open Geospatial Education and Research) cyberGIS supercomputer (Award#: 1429699).Ope
