The NPP satellite is scheduled for launch in October 2011. NPP is expected to bridge the gap between NASA's EOS satellites, which were designed as research satellites but have contributed to operations, and the future operational Joint Polar Satellite System (JPSS). The 10-year record of cloud retrievals from EOS MODIS compels us to quantify the degree of consistency between MODIS and VIIRS retrievals, therefore we are building the capability to perform MODIS-like cloud retrievals on VIIRS data, in addition to the NOAA operational retrievals. Because VIIRS and MODIS do not have identical spectral bands, we need to determine the extent to which retrieval inconsistencies are due to differences in algorithmic assumptions or spectral response. Because VIIRS lacks some absorbing spectral bands that MODIS has shown to be useful in cloud retrievals, we are investigating if including observations from CrIS can improve VIIRS cloud retrievals. In this presentation, we will explain our framework for evaluating the NPP VIIRS cloud property retrievals and will show initial retrieval results and comparisons.
