MISR Data and Information

The Multi-angle Imaging SpectroRadiometer (MISR) was successfully launched into sun-synchronous polar orbit aboard Terra, NASA's first Earth Observing System (EOS) spacecraft, on December 18, 1999. MISR measurements are designed to improve our understanding of the Earth's environment and climate. Viewing the sunlit Earth simultaneously at nine widely-spaced angles, MISR provides radiometrically and geometrically calibrated images in four spectral bands at each of the angles. Spatial sampling of 275 and 1100 meters is provided on a global basis. The MISR FAQ and Observation Concept have more details about the MISR instrument. All MISR data products are available in HDF-EOS format, and select products are available in netCDF format.

The MISR Level 3 Products are global or regional maps of select parameters from the Level 2 products and associated covariances reported on various geographic grids depending on the data product. Parameters from multiple orbits are combined to make complete Level 3 global maps at daily (D), monthly (M), quarterly (Q), and yearly (Y) time scales and regional maps associated with field campaigns at daily and monthly time scales.

Current Products

The MISR Level 2 Products are geophysical measurements derived from the Level 1B2 data. 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 Level 2 products are in swaths, each derived from a single MISR orbit, where the imagery is 380 km wide and approximately 20,000 km long.

Near Real Time Products

The Level 1 products are processed and calibrated to remove the instrument effects. The resulting products contain minimal instrument artifacts and are suitable for subsequent scientific derivations. The Level 1 products are in swaths, each derived from a single MISR orbit, where the imagery is 360 km wide and approximately 20,000 km long.

Each MISR NRT data product is available within three hours of satellite over flight as one data file per session, where a session consists of a 10 to 50 minute observation interval. The file names will include the unique start time of each session, differentiating them from standard MISR product files. The NRT versions of MISR data products employ the same retrieval algorithms as standard production, yielding equivalent science content, though not necessarily equivalent values per retrieval.
