AB: NPOESS/NPP pre-launch end to end testing is very important for establishing the long-term high quality Environmental Data Records (EDRs). In our early studies, we have developed spatial and spectral mapping technology and demonstrated the AIRS-MODIS-VIIRS band mapping approaches successfully. In this paper, we will focus on VIIRS water vapor band mapping for proxy dataset generating based on our recently established proxy database which includes the AIRS simulated MODIS, AIRS simulated VIIRS and aggregated MODIS radiances/ brightness temperatures. We demonstrate the efficacy of this approach by presenting results of the cross-comparison of water vapor band measurements from AIRS, MODIS and simulated VIIRS. We also investigate the dependence of the quality of water vapor band mapping as a function of the surface emissivity spectrum, phenomenology, and atmospheric conditions. The same approach can be used to map CrIS to VIIRS for post-launch calibration and validation. It is also valuable to keep the continuity between MODIS and VIIRS water vapor measurements. This approach can provide increased confidence in evaluating EDR retrieval algorithms performances. It also can be used to map 6.75 æm band using AIRS or CrIS measurements for water vapor algorithm testing.
