An operational data product available for both the Suomi National Polar-orbiting Partnership (S-NPP) and National Oceanic and Atmospheric Administration-20 (NOAA-20) platforms provides high-spatial-resolution infrared (IR) absorption band radiances for Visible Infrared Imaging Radiometer Suite (VIIRS) based on a VIIRS and Crosstrack Infrared Sounder (CrIS) data fusion method. This study investigates the use of these IR radiances, centered at 4.5, 6.7, 7.3, 9.7, 13.3, 13.6, 13.9, and 14.2 µm, to construct atmospheric moisture products (e.g., total precipitable water and upper tropospheric humidity) and to evaluate their accuracy. Total precipitable water (TPW) and upper tropospheric humidity (UTH) retrieved from hyperspectral sounder CrIS measurements are provided at the associated VIIRS sensor's high spatial resolution (750 m) and are compared subsequently to collocated operational Aqua Moderate Resolution Imaging Spectroradiometer (MODIS) and S-NPP VIIRS moisture products. This study suggests that the use of VIIRS IR absorption band radiances will provide continuity with Aqua MODIS moisture products.

通过使用由VIIRS和CrIS数据融合构建的红外吸收带，改善了VIIRS对流层水分的反演

可用于Suomi国家极地轨道合作伙伴关系（S-NPP）和国家海洋与大气管理局20（NOAA-20）平台的运营数据产品可为可见红外成像提供高空间分辨率的红外（IR）吸收波段辐射。基于VIIRS和Crosstrack红外测深仪（CrIS）数据融合方法的辐射计套件（VIIRS）。这项研究调查了这些IR辐射的使用，其中心为4.5、6.7、7.3、9.7、13.3、13.6、13.9和14.2  µm，以构造大气水分产物（例如，总可沉淀水和对流层上部湿度）并评估其准确性。从高光谱测深仪CrIS测量中获得的总可沉淀水（TPW）和对流层上层湿度（UTH）在相关的VIIRS传感器的高空间分辨率（750 m）处提供，随后与并置的操作Aqua中等分辨率成像光谱仪（MODIS）和S -NPP VIIRS保湿产品。这项研究表明，使用VIIRS红外吸收带辐射度将与Aqua MODIS水分产品保持连续性。
