The unprecedented slowdown in China during the COVID-19 period of November 2019 to April 2020 should have reduced pollution smog-laden cities. However, moderate resolution imaging spectrometer (MODIS) satellite retrievals aerosol optical depth (AOD) show a marked increase aerosols over Beijing–Tianjin–Hebei (BHT) region and most Northeast Central China, compared with previous winter. Fine particulate (PM2.5) data from ground monitoring stations an 19.5% Beijing January February 2020, no...
Cyanobacterial blooms are a widespread phenomenon in aquatic ecosystems worldwide, causing significant harm to the ecological environment. Lake Taihu is third-largest freshwater lake China. The region has been increasingly affected by cyanobacterial blooms, drawing greater attention from people. Currently, numerous models have developed for detecting algal bloom based on spectral characteristics. However, intuitive basis of optical detection lies water color. Therefore, constructing an model...
Surface reflectance (SR) estimation is the most critical preprocessing step for deriving geophysical parameters in multi-sensor remote sensing. Most state-of-the-art SR methods, such as vector version of Second Simulation Satellite Signal Solar Spectrum (6SV) radiative transfer (RT) model, depend on accurate information aerosol and atmospheric gases. In this study, a Simplified Robust Reflectance Estimation Method (SREM) based equations from 6SV RT without integrating particles gasses,...
The emergence of hyperspectral optical satellite sensors for ocean observation provides potential more detailed information from aquatic ecosystems.
