AB: The National Polar-orbiting Operational Environmental Satellite System (NPOESS) will become the primary platform for Earth observation in near future. As the key instrument under NPOESS and the successor of Moderate Resolution Spectroradiometer (MODIS), Visible Infrared Imager Radiometer Suite (VIIRS) is the primary instrument for land measurements in NPOESS and NPOESS Preparatory Project (NPP). With the approaching of launch, it is necessary to study the VIIRS measurements for land applications. Although there is no real VIIRS measurements before NPP launch, proxy datasets can be very valuable for land algorithm development and pre-launch testing. We have studied AIRS/MODIS/VIIRS cross-sensor calibration and validation, developed algorithms and toolkit for AIRS/MODIS/VIIRS band mapping, and constructed a testing database, which contains AIRS-simulated VIIRS thermal infrared band measurements, AIRS-simulated MODIS thermal infrared band measurements, aggregated MODIS thermal infrared band measurements as well as the corresponding scene characteristics, such as surface types, total precipitable water in air column, cloud fraction, scan angle, solar angles, and satellite angles. In this paper, we investigate the applications of proxy datasets and testing database in NPOESS and NPP land measurements pre-launch testing, especially land surface temperature retrieval and fire detection. In addition, data record continuity across multi-missions is also a very important issue for long term observation of the Earth's surface, our testing database also provides a good chance to investigate the continuity of land Environmental Data Records (EDRs) across MODIS and VIIRS.
