Level-2 Cloud Product (MOD06_L2) parameters are produced at a spatial resolution of either a 1 by 1 kilometer or a 5 by 5 kilometer (at nadir) pixel array. Each MOD06_L2 product file covers a five-minute time interval (based on the start time of each MODIS Level-1B granule). This means that for 5km resolution parameters, the output grid is 270 pixels in width by 406 pixels in length for nine consecutive granules. Every tenth granule has an output grid size of 270 by 408 pixels. For 1km resolution parameters, the output grid is 1354 pixels in width by 2030 pixels in length for nine consecutive granules. Every tenth granule has an output grid size of 1354 by 2040 pixels. The spatial resolution of individual parameters is detailed on the Format & Content page.
The image below depicts MODIS Level-2 granule coverage during a single simulated orbit. It should be noted that a granule of Level-2 MODIS data is equal to a single Level-2 MODIS product HDF file.
Computation of Geolocation in 5-km L2 Products
The geolocation in the 06_L2 MODIS product is at 5-km resolution. This geolocation is generated from 5x5 1-km L1B input and is copied from center (3,3) 1-km L1B input pixel in each 5x5-km area.
