As the successors of overdue HuanjingJianzai-1 (HJ-1) satellites and new members in Chinese Environmental Protection Disaster Monitoring Satellite Constellation, first two HuanjingJianZai-2 series (HJ-2 A/B) have been launched on September 27, 2020. Each satellite carries four sensors, including Polarized Scanning Atmospheric Corrector (PSAC), charge-coupled device (CCD) camera, hyperspectral imager (HSI) infrared spectroradiometer (IRS). Among them, PSAC is mainly used for monitoring...
The Chinese HuanjingJianzai-2 (HJ-2) A/B satellites are equipped with advanced sensors, including a Multispectral Camera (MSC) and Polarized Scanning Atmospheric Corrector (PSAC). To address the challenges of atmospheric correction (AC) for MSC’s wide-swath, wide-field images, this study proposes pixel-by-pixel method incorporating Bidirectional Reflectance Distribution Function (BRDF) effects. approach uses synchronous parameters from PSAC, an lookup table, semi-empirical BRDF model to...
The Polarization CrossFire (PCF) suite onboard the Chinese GaoFen-5(02) satellite has been sophisticatedly composed by Particulate Observing Scanning Polarimeter (POSP) and Directional Polarimetric Camera (DPC). Among them, DPC is a multi-angle sequential measurement polarization imager, while POSP cross-track scanning simultaneous polarimeter with corresponding radiometric polarimetric calibrators, which can theoretically be used for cross comparison calibration DPC. After data...
The spectral broadening by Rayleigh backscattering can cause large changes in water vapor echo signals, causing errors when the concentration is inversed differential absorption lidar (DIAL). A correction algorithm proposed to revise due effect of laser broadening. relative are calculated cases different aerosol distribution and temperature before after correction. results show that measurement Doppler more than 5% a 2% error corrected for case smooth, background distribution. However, high...
