We made an experimental vicarious calibration of the Moderate Resolution Imaging Spectroradiometer (MODIS) Airborne Simulator (MAS) thermal infrared (TIR) channel data acquired in the field campaign near Mono Lake, Calif. on 10 March 1998 to demonstrate the advantage of using high-elevation sites in dry atmospheric conditions for vicarious calibration. With three lake-surface sites and one snow...

The Multi-angle Imaging SpectroRadiometer (MISR) is a part of the payload for NASA’s Terra spacecraft launched in December 1999. The MISR instrument continuously acquires a systematic, global, multi-angle imagery in reflected sunlight in order to support and improve studies of the Earth ecology and climate. This paper focuses on the photogrammetric aspect of the data production and discusses qu...

[1] Using one year (2000–2001) of merged Multiangle Imaging SpectroRadiometer (MISR), Moderate Resolution Imaging SpectroRadiometer (MODIS) and Clouds and the Earth’s Radiant Energy System (CERES) data sets from NASA’s Terra satellite, we estimate the top of atmosphere cloud-free direct radiative effect (DRE) of aerosols over global land areas. The global mean shortwave DRE is 5.1 ± 1.1 Wm 2 al...
