The global maps contain the grid-cell mean fractions of the three mentioned parameters, their variance within the grid cells, and - for the forest cover fraction - the grid-cell mean standard deviation. In addition, the data set includes maps of the number of valid forest cover fraction values at 250 m resolution per 0.5 degree grid cell, a grid cell mean quality flag and fractions of the two most abundant quality flags (primary and secondary). Generally all valid data are used; the user is advised to check the quality flags to eventually discard data of low quality.</p>\n\n<p><strong>TableOfContents:</strong> grid cell mean forest cover fraction; grid cell mean forest cover fraction standard deviation; forest cover fraction variance within grid cell; grid cell mean vegetation cover fraction; vegetation cover fraction variance within grid cell; non-vegetated area cover fraction; non-vegetated area cover fraction variance within grid cell; number of useful vegetation cover fraction values per grid cell; grid cell mean quality flag; primary quality flag fraction; secondary quality flag fraction</p>\n\n<p><strong>Technical Info:</strong> dimension: 720 columns x 360 rows x unlimited; temporalExtent_startDate: 2023-03-06; temporalExtent_endDate: 2024-03-04; temporalResolution: yearly; spatialResolution: 0.5; spatialResolutionUnit: degrees; horizontalResolutionXdirection: 0.5; horizontalResolutionXdirectionUnit: degrees; horizontalResolutionYdirection: 0.5; horizontalResolutionYdirectionUnit: degrees; verticalResolution: none; verticalResolutionUnit: none; verticalStart: none; verticalEnd: none; instrumentName: MODerate Resolution Spectroradiometer (MODIS); instrumentType: visible_to_infrared_spectroradiometer; instrumentLocation: Earth Observation Satellite (EOS) Terra; instrumentProvider: NOAA/NASA</p>\n\n<p><strong>Methods:</strong> [1] <a href=\"https://lpdaac.usgs.gov/products/mod44bv061/\">https://lpdaac.usgs.gov/products/mod44bv061/</a>; [2] Townshend, J., et al., User Guide for the MODIS Vegetation Continuous Fields product Collection 6.1, verison 1, <a href=\"https://lpdaac.usgs.gov/documents/1494/MOD44B_User_Guide_V61pdf\">https://lpdaac.usgs.gov/documents/1494/MOD44B_User_Guide_V61pdf</a>; [3] Algorithm Theoretical Basis Document (ATBD), <a href=\"https://lpdaac.usgs.gov/documents/113/MOD44B_ATBD.pdf\">https://lpdaac.usgs.gov/documents/113/MOD44B_ATBD.pdf</a>; [4] Carroll, M., et al., 2011.
