Level 1 Near Real Time
The MISR Near Real Time Level 1 data products consist of radiance measurements organized in 10-50 minute session representing a portion of a single MISR orbit. Measurements are obtained throughout the 380 km MISR swath and projected onto a Space-Oblique Mercator (SOM) map grid. The Ellipsoid-projected and Terrain-projected top-of-atmosphere (TOA) radiance products provide measurements respectively resampled onto the WGS84 reference ellipsoid and onto the topography of a digital elevation model. Spatial sampling is 275 m in all bands of MISR’s nadir camera, and in the red band of the other eight (off-nadir) cameras. The remaining channels are sampled at 1.1 km.
