Product Description:
The Level 2 MODIS Cloud Mask Product(MOD35_L2 and MYD35_L2) consists of global cloud mask, quality assurance, and other ancillary parameters. The visible and infrared threshold and consistency tests are used to specify confidence levels that an unobstructed view of the Earth's surface is observed. An indication of shadows affecting the scene is also provided. MOD35_L2 and MYD35_L2 parameters are produced at spatial resolution of 1-km and 250-m at nadir. Including ancillary parameters, this product consists of 9 parameters.

Production Frequency:
~288 files per day

Spatial Coverage:
Global Coverage
5 Minute Granule Size = 2330 x 2030 pixels

Spatial Resolution:
250x250 m & 1x1 km at nadir

File Size:
~15 MB (maximum)
