The MODerate resolution Imaging Spectroradiometer (MODIS) aboard both NASA's Terra and Aqua satellites is making near global daily observations of the earth in a wide spectral range (0.41 to 15 µm). These measurements are used to derive spectral aerosol optical thickness and aerosol size parameters over both land and ocean. The aerosol products available(More)
Observations of the aerosol optical thickness (AOT) by the MODIS instruments aboard Terra and Aqua satellites are being used extensively for applications to climate and air quality studies, as indicated from 28 publications in 2004 alone. Data quality is essential for these studies. Here we add to the published MODIS validations by investigating the effects(More)
[1] In 2004 NASA plans to launch the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations— CALIPSO mission, with a two-wavelength lidar aboard. CALIPSO will fly in formation with the Moderate Resolution Imaging Spectro-Radiometer (MODIS) on the Aqua satellite. Here we present inversions of combined aircraft lidar and MODIS data to study the(More)
