MISR Product and Format Definitions

Data Products

More detailed information can be found in the MISR Handbook or FAQ.
Level 1 (L1) Level 1 data products are processed and calibrated to remove many of the instrument effects. The resulting products thus contain minimal instrument artifacts and are most suitable for subsequent scientific derivations. These include raw radiance data (Level 1A); radiometrically calibrated imagery (Level 1B1); geolocated, co-registered, map-projected radiance (Level 1B2); browse data; and geometric parameters on a swath-by-swath basis.
Level 2 (L2) Level 2 Products are geophysical measurements (ex. aerosol optical depth) derived from the Level 1B2 data.
Level 3 (L3) Level 3 products are globally gridded statistical summaries (daily, monthly, quarterly, and yearly) of a range of parameters from select Level 1 and Level 2 products. At Level 3 the product parameters from multiple swaths are combined to make complete, global maps.

Output Format

More detailed information can be found in the MISR Handbook or FAQ.
Stacked-block Stacked-block HDF-EOS format is a MISR specific extension to the HDF-EOS library that is only used by MISR and is not widely supported by third party data analysis tools. Tools which support HDF-EOS or HDF can usually import stacked-block data to a limited extent.
Conventional The conventional HDF-EOS format is an alternative format that uses only common HDF-EOS elements, specifically excluding use of the stacked-block extensions. As a result, the conventional HDF-EOS format should be easily imported into any tools that support generic HDF-EOS.
