AIRS/Aqua L1B Infrared (IR) geolocated and calibrated radiances V005 (AIRIBRAD) at GES DISC

WARNING: On 2021/09/23 the EOS Aqua executed a Deep Space Maneuver (DSM). In the DSM, the spacecraft is turned such that the normal Earth field of regard is deep space.The thermal impact of the DSM caused a shift of the centroids of spectral response functions (SRF) of about 1% of the width of the SRF, equivalent to a frequency shift of 9 parts per million. This shift is reflected in the “spectral_freq” parameter (observed frequencies) in the L1b v5 files for each 6 minute granule. The magnitude of the effect on brightness temperatures (BT) depends on the spectral gradient of each channel. Max...警告：2021年9月23日，地球观测系统（Earth Observing System, EOS）Aqua卫星执行了深空机动（Deep Space Maneuver, DSM）。本次深空机动中，卫星姿态发生调整，原本指向地球的常规视场转为指向深空。此次机动带来的热影响导致光谱响应函数（Spectral Response Functions, SRF）的质心发生偏移，偏移量约为SRF带宽的1%，等效于9百万分率的频移。该偏移会体现在每6分钟数据粒对应的L1b v5级数据文件中的"spectral_freq"参数（即观测频率）中。其对亮温（Brightness Temperatures, BT）的影响幅度取决于各通道的光谱梯度，最大……
