Abstract

In this work, the current performance of the calibrated Joint Polar Satellite System (JPSS) Cross-track Infrared Sensor (CrIS) observations is reported. The CrIS instrument is currently on-board the Suomi National Polar-orbiting Partnership (SNPP) and NOAA-20 spacecraft, and planned for the JPSS-2, -3 and -4 satellites. Presently, calibrated and validated CrIS observations, in the form of sensor data record (SDR) products, are being assimilated by operational NWP models and atmospheric retrieval systems. CrIS measurements from SNPP and NOAA-20 are expected to improve our understanding of the dynamics of the atmosphere due to the higher temporal and spatial coverage resulting from optimally blending the hyperspectral Earth observations. This work also reports recent improvements performed on the CrIS SDR products, including: 1) the implementation of the polarization correction, 2) the optimization of the spike detection and correction algorithm, and 3) the optimization of the lunar intrusion algorithm.

SNPP和NOAA-20 CrIS传感器数据记录产品的性能

本文报道了校准后的联合极轨卫星系统(JPSS)交叉航迹红外传感器(CrIS)观测数据的现状。CrIS仪器目前安装在芬兰国家极轨伙伴关系(SNPP)和NOAA-20航天器上，并计划用于JPSS-2、3和4卫星。目前，校准和验证的CrIS观测，以传感器数据记录(SDR)产品的形式，正在被业务NWP模型和大气检索系统吸收。来自SNPP和NOAA-20的CrIS测量预计将提高我们对大气动力学的理解，因为最佳混合高光谱地球观测结果带来了更高的时空覆盖率。本文还报道了CrIS SDR产品的最新改进，包括:1)极化校正的实现，2)尖峰检测和校正算法的优化，以及3)月球入侵算法的优化。
