Abstract. Various instrumental or geophysical artifacts, such as saturation, stray light obstruction of (either coming from the instrument related to solar eclipses), negatively impact satellite measured ultraviolet and visible Earthshine radiance spectra downstream retrievals atmospheric surface properties derived these spectra. In addition, excessive noise cosmic-ray impacts, prevalent within...

Global measurements of total ozone are necessary to evaluate hole recovery above Antarctica. The Environmental Trace Gases Monitoring Instrument (EMI) onboard GaoFen 5, launched in May 2018, was developed measure and monitor the global column (TOC) distributions other trace gases. In this study, some first TOC results EMI using differential optical absorption spectroscopy (DOAS) method validati...

Air pollutants adversely affect human health, and thus a global improvement in air quality is urgent. A Geostationary Environment Monitoring Spectrometer (GEMS) was mounted on the geostationary Chollian 2B satellite 2020 to observe spatial distribution of pollution, sequential observations have been released since July 2022. The reliability GEMS must be analyzed because it first payload Earth o...

The spatial and temporal variation of satellite derived pre-monsoonal Aerosol Optical Depth (AOD) over the Indian region has been studied using long-term (2005–2021) data from Moderate Resolution Imaging Spectroradiometer (MODIS) Ozone Monitoring Instrument (OMI). In particular, three zones were selected, based on dominance natural, anthropogenic mixture both types aerosols. seasonal average AO...

Abstract. Information about the height and loading of sulfur dioxide (SO2) plumes from volcanic eruptions is crucial for aviation safety assessing effect sulfate aerosols on climate. While SO2 layer has been successfully retrieved backscattered Earthshine ultraviolet (UV) radiances measured by Ozone Monitoring Instrument (OMI), previously demonstrated techniques are computationally intensive no...

Formaldehyde (HCHO) is the most important carcinogen in outdoor air among the 187 hazardous air pollutants (HAPs) identified by the U.S. Environmental Protection Agency (EPA), not including ozone and particulate matter. However, surface observations of HCHO are sparse and the EPA monitoring network could be prone to positive interferences. Here we use 2005-2016 summertime HCHO column data from ...

Abstract. Mainland and maritime Southeast Asia is home to more than 655 million people, representing nearly 10 % of the global population. The dry season in this region typically associated with intense biomass burning activity, which leads a significant increase surface air pollutants that are harmful human health, including ozone (O3). Latitude-based differences land use distinguish two regio...

A technique for evaluating the radiometric calibration of satellite-born radiometers has been developed utilizing the stable reflectance of the Antarctic land mass. Previously, the scene radiances measured over the Antarctic and Greenland land masses were used to monitor time evolution of sensor radiometric sensitivity and to compare instruments with similar spectral responses. Through the use ...

Retrievals of tropospheric nitrogen dioxide (NO2) from the Ozone Monitoring Instrument (OMI) are subject to errors in the treatments of aerosols, surface reflectance anisotropy, and vertical profile of NO2. Here we quantify the influences over China via an improved retrieval process. We explicitly account for aerosol optical effects (simulated by nested GEOS-Chem at 0.667 long. × 0.5 lat. and c...
