Estimation of the PM2.5 and PM10 Mass Concentration over Land from FY-4A Aerosol Optical Depth Data

open access: yes, 2021
The purpose of this study is to estimate the particulate matter (PM2.5 and PM10) in China using the improved geographically and temporally weighted regression (IGTWR) model and Fengyun (FY-4A) aerosol optical depth (AOD) data.

Comparison of FY-4A/AGRI SST with Himawari-8/AHI and In Situ SST

open access: yes, 2023
The Fengyun-4A (FY-4A) satellite is a new-generation geostationary meteorological satellite developed by China. The advanced geosynchronous radiation imager (AGRI), one of the key payloads onboard FY-4A, can monitor sea surface temperature (SST).

Robust Tracking Control for Rendezvous in Near‐Circular Orbits

open access: yesMathematical Problems in Engineering, Volume 2013, Issue 1, 2013., 2013
This paper investigates a robust guaranteed cost tracking control problem for thrust‐limited spacecraft rendezvous in near‐circular orbits. Relative motion model is established based on the two‐body problem with noncircularity of the target orbit described as a parameter uncertainty.

Validation of FY-4A Temperature Profiles by Radiosonde Observations in Taklimakan Desert in China

open access: yes, 2023
The atmospheric temperature profiles (ATPs) retrieved through the geostationary Interferometric Infrared Sounder (GIIRS) onboard the FY-4A satellite (GIIRS/FY-4A) can effectively fill the gap of the scarce conventional sounding data in the Taklimakan ...

An Investigation of the Fengyun-4A/B GIIRS Performance on Temperature and Humidity Retrievals

open access: yes, 2022
The Fengyun-4A/B (FY-4A/B) geostationary satellite carries the Geostationary Interferometric Infrared Sounder (GIIRS). The instrument parameters of the GIIRS on FY-4A and FY-4B are not exactly the same, which is crucial for the atmospheric temperature ...
