Moderate Resolution Imaging Spectroradiometer (MODIS)/Aqua Ocean Color Reprocessing 2022.0

Reprocessing 2022.0 is a multi-mission reprocessing to incorporate updates in instrument calibration, vicarious calibration, new ancillary sources and algorithm improvements. The affected missions are Coastal Zone Color Scanner Experiment (CZCS), Sea-viewing Wide Field-of-view Sensor (SeaWiFS), Ocean Color and Temperature Scanner (OCTS), Medium Resolution Imaging Spectrometer (MERIS), Moderate Resolution Imaging Spectroradiometer (MODIS) on Aqua and Terra, Visible Infrared Imaging Radiometer Suite (VIIRS) on Suomi National Polar-orbiting Partnership and National Oceanic and Atmospheric Administration (NOAA)-20, Ocean and Land Colour Instrument (OLCI) on Sentinel-3A and Sentinel-3B, Geostationary Ocean Color Imager (GOCI), and Hyperspectral Imager for the Coastal Ocean (HICO). Here we describe the changes and results specific to MODIS Aqua (MODISA).

2022.0版再处理项目为一项多任务再处理流程，旨在整合仪器定标、替代定标、新型辅助数据源及算法改进等更新内容。本次涉及的卫星任务包括：海岸带彩色扫描仪实验（CZCS）、宽视场海洋观测传感器（SeaWiFS）、海洋水色与温度扫描仪（OCTS）、中分辨率成像光谱仪（MERIS）、Aqua与Terra卫星搭载的中分辨率成像光谱辐射计（MODIS）、苏奥米国家极轨伙伴卫星与美国国家海洋和大气管理局（NOAA）-20卫星搭载的可见红外成像辐射计套件（VIIRS）、Sentinel-3A与Sentinel-3B卫星搭载的海洋与陆地颜色仪（OLCI）、静止轨道海洋水色成像仪（GOCI）以及海岸带高光谱成像仪（HICO）。本文针对Aqua卫星搭载的MODIS（简称MODISA），详细阐述本次再处理的具体变更与成果。
