Retrieval of UV–visible aerosol absorption using AERONET and OMI–MODIS synergy: spatial and temporal variability across major aerosol environments [PDF]

open access: yesAtmospheric Measurement Techniques, 2022
Measuring spectral aerosol absorption remains a challenging task in aerosol studies, especially in the UV region, where ground and airborne measurements are sparse.

An Atmospheric Correction Method over Bright and Stable Surfaces for Moderate to High Spatial-Resolution Optical Remotely Sensed Imagery

open access: yesRemote Sensing, 2020
Although many attempts have been made, it has remained a challenge to retrieve the aerosol optical depth (AOD) at 550 nm from moderate to high spatial-resolution (MHSR) optical remotely sensed imagery in arid areas with bright surfaces, such as deserts ...

Aerosol models from the AERONET database: application to surface reflectance validation [PDF]

open access: yesAtmospheric Measurement Techniques, 2022
Abstract. Aerosols play a critical role in radiative transfer within the atmosphere, and they have a significant impact on climate change. In this paper, we propose and implement a framework for developing an aerosol model using their microphysical properties. Such microphysical properties as the size distribution, the complex refractive index, and the

Application of Optimal Interpolation to Spatially and Temporally Sparse Observations of Aerosol Optical Depth

open access: yesAtmosphere, 2022
Aerosol optical depth (AOD) is one of the basic characteristics of atmospheric aerosol. A global ground-based network of sun and sky photometers, the Aerosol Robotic Network (AERONET) provides AOD data with low uncertainty.

Observationally-constrained estimates of global fine-mode AOD [PDF]

open access: yesAtmospheric Chemistry and Physics, 2013
Small aerosols are mostly anthropogenic, and the fine-mode aerosol optical depth (fAOD) can be used to infer anthropogenic aerosol amounts. We estimate AOD and fAOD globally on a monthly time scale from 2001 to 2010 by integrating monthly satellite-based

AERONET data–based determination of aerosol types

open access: yesAtmospheric Pollution Research, 2015
AbstractAerosols are among the most interesting topics investigated by researchers because of their complicated characteristics and poor quantification. Moreover, significant uncertainties are associated with changes in the Earth's radiation budget. Previous studies have shown numerous difficulties and challenges in quantifying aerosol influences.

Evaluation of VIIRS Land Aerosol Model Selection with AERONET Measurements [PDF]

open access: yesInternational Journal of Environmental Research and Public Health, 2017
The Visible Infrared Imaging Radiometer Suite (VIIRS) is a next-generation polar-orbiting operational environmental sensor with a capability for global aerosol observations. Identifying land aerosol types is important because aerosol types are a basic input in retrieving aerosol optical properties for VIIRS. The VIIRS algorithm can automatically select
