Ammonia (NH3) is an important alkaline gas in the atmosphere, which can react with acid gas in the air leading to the formation of haze through dry and wet deposition. Therefore, the content of NH3 in the air is one of the importa

As a powerful tool for active remote sensing of the atmosphere, lidar can be used to monitor the spatial and temporal distribution of clouds automatically and continuously. An improved cloud detection algorithm based on differenti

The available extinction coefficient of the main land areas in China are studied from the perspective of optical engineering application. Firsty, the relevant historical data are analyzed from three aspects: overall average situat

Large-aperture scintillometer can be used for regional surface heat flux observations and is also an effective tool for measuring surface heat fluxes at the satellite image scale. For the improvement of satellite product algorithm

To accurately grasp the changes of the temporal and spatial pattern of carbon emissions and formulate regional differential emission reduction policies according to local conditions is a widely concerned in current society. Based

To address the problem of the detection performance calibration of differential absorption lidar in mid-infrared band, a straight-through gas cell for differential absorption detection in mid-infrared band was designed and constru

The concentration of chlorophyll a in inland water determines the plankton content, which is a main index to measure the eutrophication degree of water, and is also one of the important factors affecting the apparent reflectance s

Based on the daily average concentration monitoring data of important pollutants and the meteorological data at ground national control stations from January 1, 2019 to December 31, 2020, a comprehensive assessment of urban air qu

Based on ground-based Fourier transform infrared remote sensing and in-situ surface measurement, the variation of atmospheric CH4 and CO2 concentrations in Hefei City, China, from January 2016 to December 2017 were investigated. T
