A consistent aerosol optical depth (AOD) dataset over mainland China by integration of several AOD products

Atmospheric Environment, 2015
Abstract The Moderate Resolution Imaging Spectroradiometer (MODIS), the Multiangle Imaging Spectroradiometer (MISR) and the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) provide validated aerosol optical depth (AOD) products over both land and ocean.

Retrieval of Aerosol Optical Depth (AOD) from the Landsat8 Oli Observations Over Beijing

IGARSS 2020 - 2020 IEEE International Geoscience and Remote Sensing Symposium, 2020
The deep blue (DB) algorithm is usually used for retrieval of AOD on high reflectivity surfaces, which cover complex surface types. However, due to low spatial resolutions, it shows limited information details in urban areas and cannot fully display the aerosol variation characteristics. Now, a new aerosol retrieval algorithm with a priori Land Surface

Aerosol optical depth assimilation for a modal aerosol model: Implementation and application in AOD forecasts over East Asia

Science of The Total Environment, 2020
A new aerosol optical depth (AOD) data assimilation (DA) module was developed in Gridpoint Statistical Interpolation (GSI) 3-dimensional variational (3DVAR) system, named FastJ/CRTM-AOD DA module. And applied to the Modal Aerosol Dynamics Model for Europe with the Secondary Organic Aerosol Model (MADE/SORGAM) in the Weather Research and Forecasting ...

Retrieval of aerosol optical depth (AOD) using NOAA AVHRR data in an alpine environment

SPIE Proceedings, 2004
The aim of this study is the retrieval of aerosol optical depth from the National Oceanic and Atmospheric Administration (NOAA) Advanced Very High Resolution Radiometer (AVHRR) sensor over land. The region of interest covers central Europe ranging from 50°N to 40.5°N and from 0°E to 17°E including the European Alps.

Machine-Learning Approaches for Assessing Aerosol Optical Depth (AOD) in Ghana, West Africa

In the field of environmental health, assessing air pollution exposure has historically posed challenges, primarily due to sparse ground observation networks. To overcome this limitation, satellite remote sensing of aerosols provides a valuable tool for monitoring air quality and estimating particulate matter concentration (PM) at the surface.

Improving Aerosol Optical Depth (AOD) data via Regression Methods derived from Mean Combustion Efficiency (MCE) and Aerosol Index (UVAI) Data Products

2022
Aerosol optical depth (AOD) is a valuable parameter that reflects the density and characteristics of atmospheric aerosols, providing critical insight for studies into processes like climate change or ecological situation assessment. However, AOD data limitations arise from dense cloud cover, rendering a lack of variables over certain coverage areas. To
