The MODIS Water Vapor (MOD05_L2) product contains data that has a spatial resolution (pixel size) of 1 x 1 kilometers (at nadir) or 5 x 5 kilometers (at nadir). Each MOD05_L2 product file covers a five-minute time interval (based on the start time of each MODIS Level-1B granule), which means the MOD05_L2 output grid is 1350 1-km pixels in width and 2030 1-km pixels in length (or 270 by 406 5-km pixels) for nine consecutive granules. Every tenth granule has an output grid size of 1350 by 2040 pixels (or 270 by 408).

Granule Coverage

The image below depicts MODIS Level-2 granule coverage during a single simulated orbit. Twenty consecutive granules are depicted. It should be noted that a granule of Level-2 MODIS data is defined as a single Level-2 MODIS product HDF file.
