Abstract. The imaging instruments on the polar-orbiting S-NPP and NOAA-20 satellite platforms [e.g., Visible Infrared Imaging Radiometer Suite (VIIRS)] and on geostationary GOES and Himawari platforms [e.g., Advanced Baseline Imager (ABI) and Advanced Himawari Imager (AHI)] have high horizontal spatial resolution but coarse vertical information about tropospheric gases and temperatures. An approach for fusing a high spatial resolution imager (e.g., VIIRS, ABI, and AHI) and a high information content sounder or trace gas monitor [e.g., Cross-track Infrared Sounder (CrIS) and TROPOspheric Monitoring Instrument (TROPOMI)] offers the opportunity to construct retrieval products (e.g., trace gas concentrations of CO, SO2, and NH3) via product fusion at high spatial resolution. Furthermore, these products can also be provided at high temporal resolution when geostationary imager (ABI and AHI) data are used in the product fusion. Promising results from VIIRS/CrIS, VIIRS/TROPOMI, and AHI/TROPOMI fusion are presented.

通过多卫星数据融合增强痕量气体测定的方法

摘要。极轨 S-NPP 和 NOAA-20 卫星平台上的成像仪器 [例如，可见红外成像辐射计套件 (VIIRS)] 以及地球静止轨道 GOES 和 Himawari 平台上的成像仪器 [例如，高级基线成像仪 (ABI) 和高级 Himawari 成像仪 ( AHI)] 具有较高的水平空间分辨率，但关于对流层气体和温度的垂直信息较为粗糙。一种融合高空间分辨率成像仪（例如 VIIRS、ABI 和 AHI）和高信息含量测深仪或痕量气体监测仪 [例如跨轨红外测深仪 (CrIS) 和对流层监测仪 (TROPOMI)] 的方法提供了有机会通过产品融合以高空间分辨率构建检索产品（例如，CO、SO2 和 NH3 的痕量气体浓度）。此外，当在产品融合中使用地球静止成像仪（ABI 和 AHI）数据时，这些产品也可以以高时间分辨率提供。展示了来自 VIIRS/CrIS、VIIRS/TROPOMI 和 AHI/TROPOMI 融合的有希望的结果。
