12/01/2007 | The entire mission is being reprocessed at this level.
Data Product Specification Rev Q (PDF). No user visible changes, other than updates to the underlying Level 2 data that is being summarized (see TOA/Cloud Albedo and TOA/Cloud versioning pages for details). |

| F06_0022 (albedo) F02_0022 (cloud) |
08/01/2007 | Data Product Specification Rev P (PDF).
Now have a time dimension in all fields for netCDF files (even though there is only one time value). This was a change requested by data product users to integrate better with existing tools such as vcdat that expect a time dimension. |

| F06_0020 (albedo) F02_0020 (cloud) |
10/02/2006 | Data Product Specification Rev O (PDF).
Added netCDF version. These products are the same format as the HDF-EOS products except there is one file for each grid resolution. Example file name: MISR_AM1_CGCL_0_5_DEG_JUN_01_2003_F02_0020.nc |

Initial baseline for Level 3 Component Global Cloud Product (CGCL) public release. Baseline ancillary files:
For Albedo (CGAL) product, this version fixes an error in the "Time of Observation" data, which in the previous version was missing many Level 2 observations. The actual Level 3 averages contained all of these observations, they simply were not being recorded in the "Time of Observation" vdata. The current version does correctly record all the Level 2 observations. |
