MISR Regional Imagery: Overview | Products | Data Quality | Map Projection | File Format | View Data | Download Data
There are currently three types of MISR Regional products: Radiance, Aerosol, and Land Surface. Each product summarizes selected parameters from one Level 1 or Level 2 product.
Further information about the Level 1 and Level 2 data products can be found on the INTEX-B data table, and by consulting the Algorithm Theoretical Basis Documents.
Before using MISR Data products, please read the documentation including Data Quality and Versioning statements available from the INTEX-B data table.
Images available on this web site include the following parameters:
