The Geostationary Interferometric Infrared Sounder (GIIRS) on board China’s FengYun-4 satellite series provides a unique opportunity to monitor the tropospheric composition over Asia using hyperspectral infrared observations from geostationary orbit. In this study, we retrieve atmospheric carbon monoxide (CO), ammonia (NH3), formic acid (HCOOH) and ozone (O3) for first two years July 2022 June 2024 FengYun Atmospheric Retrieval (FY-GeoAIR) algorithm. GIIRS measures these compounds...
Global navigation satellite systems (GNSS) tropospheric tomography can be used to build a three-dimensional water vapor field. In traditional tomography, the signals crossing from four sides of tomographic region are not utilized. To make best use these valuable side-crossing signals, an improved model based on back propagation artificial neural network (BP-ANN) is proposed. new model, inside part slant wet delay (SWD) signal divided into two sections: isotropic and anisotropic components....
The tropospheric tomography is an ill-posed inversion problem due to the sparsity of Global Navigation Satellite Systems (GNSS) stations and limitation on projection angles GNSS signals, which in turn affects stability robustness tomographic solution. To address this, a new algorithm, named two-step projected iterative algorithm (TSPIA), proposed. wet refractivity (WR) field was constructed two steps: first, preprocessing for initial input values performed, then its resultant solution into...
