S2K Data Set Available

Submitted by ORNL DAAC Staff on

The ORNL DAAC announces the release of the data set "SAFARI 2000 MISR Level 2 Data, Southern Africa, Dry Season 2000".

This data set is a product of the Southern African Regional Science Initiative containing 240 HDF-EOS formatted MISR Level 2 Top-of-Atmosphere/Cloud and Aerosol/Surface Products focused in a southern African study area which includes: Botswana, Lesotho, Malawi, Mozambique, Namibia, South Africa, Swaziland, Zambia, and Zimbabwe.

The MISR Level 2 Products are geophysical measurements derived from the Level 1B2 data which consists of parameters that have been geometrically corrected and projected to a standard map grid. The products are in swaths, each derived from a single MISR orbit, where the imagery is 360 km wide and approximately 20,000 km long.

The Top-of-Atmosphere (TOA)/Cloud Products contain measurements of TOA bidirectional reflectance factors, stereoscopically-derived cloud and land (reflecting level) elevation, cloud fraction, cloud texture, and other related parameters. The Level 2 Aerosol/Surface Product includes a range of parameters such as tropospheric aerosol optical depth; aerosol composition and size; surface directional reflectance factors and bi-hemispherical reflectance; and other related parameters.

The Southern African Regional Science Initiative - SAFARI 2000 - was an international science initiative aimed at developing a better understanding of the southern African earth-atmosphere-human system. The goal of SAFARI 2000 was to identify and understand the relationships between physical, chemical, biological and anthropogenic processes that underlie the biogeophysical and biogeochemical systems of southern Africa. Particular emphasis was placed upon biogenic, pyrogenic and anthropogenic emissions, including: characterization and quantification, transport and transformation in the atmosphere, influence on regional climate and meteorology, eventual deposition, and the effects of deposition on ecosystems.
