Aerosol Optical Depth Prediction from Satellite Observations
Aerosols are small airborne particles that both reflect and absorb incoming solar radiation and whose effect on the Earth’s radiation budget is one of the biggest challenges of current climate research. To help address this challenge, numerous satellite sensors are employed to achieve globalscale monitoring of aerosols. Given the satellite measurements, the common objective is prediction of Aer...
متن کاملAerosol Optical Depth Spatial and Temporal Variability Using Satellite Data Over Indian Major Cities
Introduction: The study’s main aim is to investigate the long-term variation of Aerosol Optical Depth (AOD). It also aims to show the relationship between meteorological parameters. This study evaluates long-term (2010 to 2021) special and temporal changes over major Indian regions using satellite-based data from NASA’s Terra Satellite. Materials and Methods: This study was carried out during ...
متن کاملSatellite-derived aerosol optical depth over dark water from MISR and MODIS: Comparisons with AERONET and implications for climatological studies
[1] Although the current Multiangle Imaging Spectroradiometer (MISR) and Moderate Resolution Imaging Spectroradiometer (MODIS) satellite passive remote sensing midvisible aerosol optical thickness (AOT) products are accurate overall to about 0.05 or 20%, they differ systematically on a global, monthly average basis, by about 0.03 to 0.05. Some key climate change and other applications require a...
متن کاملA long-term record of aerosol optical depth from TOMS observations and comparison to AERONET measurements
Observations of backscattered near-ultraviolet radiation from the Total Ozone Mapping Spectrometer (TOMS) on board the Nimbus-7 (1979–92) and the Earth Probe (mid-1996 to present) satellites have been used to derive a long-term record of aerosol optical depth over oceans and continents. The retrieval technique applied to the TOMS data makes use of two unique advantages of near-UV remote sensing...
متن کاملValidation of Aerosol Optical Depth Retrieved from SPOT Satellite Images
In this paper, the image-based retrieval algorithm of aerosol characteristics and surface reflectance is used to retrieve the AOD from SPOT images. The validation of retrieved AOD is made possible by using the AERONET data. Five SPOT satellite images are used to testify the algorithm. The results show that the RMSE of the retrieved AOD are 0.12 and 0.08 in XS1 and XS2 bands, although the larges...
