A 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 کاملAerosol 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 کاملComparison of MODIS and AERONET derived aerosol optical depth over the Ganga Basin, India
The Moderate Resolution Imaging Spectroradiometer (MODIS) onboard EOS Terra measures global aerosol optical depth and optical properties since 2000. MODIS aerosol products are freely available and are being used for numerous studies. In this paper, we present a comparison of aerosol optical depth (AOD) retrieved from MODIS with Aerosol Robotic Network (AERONET) data for the year 2004 over Kanpu...

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...
