Aerosol Optical Depth Retrieval on Particulate Observing Scanning Polarimeter (POSP) Data over Land using a new Look-up table (LUT) Search Method

“…Detailed information on the POSP sensor is given in Table 1. Since it is equipped with on-board radiometric and polarimetric calibration systems of exceptional accuracy, POSP achieves a radiometric calibration accuracy (ΔI) within 5% and a polarimetric calibration accuracy (ΔDOLP) within 0.005 of linear polarization (Li et al 2022b).…”

“…The development holds immense importance for the global scienti c community. The POSP sensor is an important sensor among these advancements, which is a high-precision polarimetric scanner rst mounted on the sun-synchronous orbiting satellite GF5-02 launched on September 7, 2021 (Li et al 2022a). The rst POSP AOD algorithm was proposed during the POSP on-orbit period, and it utilized the long-term reconstructed land surface re ectance (derived from MODIS LSR product) to construct the surface constraints supporting AOD retrieval (Shi et al, 2023).…”

The Simulated Source Apportionment of Light Absorbing Aerosols: Effects of Microphysical Properties of Partially‐Coated Black Carbon

“…Based on the aerosol absorption optical depth (AAOD) of aerosols obtained from ground based measurements, such as the Aerosol Robotic Network (AERONET), similar methods were also used (Russell et al., 2010; Schuster et al., 2016). In addition, satellite remote sensing can also be used to retrieve multi‐wavelength AAOD, and some studies have also proposed the method of collaborative monitoring through a polarized satellite constellation of AAOD (Dubovik et al., 2011; Z. Li et al., 2022). Therefore, the ground‐based source attribution method can be extended to the coordinated remote sensing monitoring by satellite constellations in the future.…”

Study on the calibration of full polarization imager

“…Especially in recent years, satellite polarimetric remote sensing has developed rapidly. Such as POLDER (Polarization and Directionality of the Earth's Reflectance instrument) sensor, GOME (Global Ozone Monitoring Experiment) sensor, SCIAMACHY (SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY) sensor, MAP (Multi-Angle Polarimeter) sensor, APS (Aerosol Polarimetry Sensor) sensor, HARP (Hyper-Angular Rainbow Polarimeter) sensor, CALIOP (Cloud-Aerosol LIdar with Orthogonal Polarization) sensor, MAIA (Multi-Angle Imager for Aerosols) sensor, CAPI (Cloud and Aerosol Polarization Imager) sensor, MAI (Multi-Angle polarization Imager) sensor, DPC (Directional Polarimetric Camera) sensor, POSP (Particulate Observing Scanning Polarimeter) sensor, PCF (Polarization CrossFire Suite) sensor, SGLI (Second Generation Global Imager) sensor, and MISR (Multiangle Imaging SpectroRadiometer) sensor, etc [ [15] , [16] , [17] , [18] , [19] , [20] , [21] , [22] ]. The application of commercial polarization CCD (Charge-Coupled Device) has also made significant progress.…”
