MOD44W_005

MODIS/Terra Land Water Mask Derived from MODIS and SRTM L3 Global 250m SIN Grid V005

Version 005
  • Abstract
    The MODIS 250 m land-water mask (Short Name: MOD44W) is an improvement over the existing MODIS Nadir Bidirectional Reflectance Distribution Function (BRDF)-Adjusted Reflectance (NBAR) and MODIS land cover-based global land-water mask (Salomon et al., 2004). The MODIS NBAR and land cover–based mask was itself an improved version of the EOS DEM-based land-water mask (Logan et al., 1999). This MODIS 250 m mask is primarily created with three different data inputs: 1. The Shuttle Radar Topography Mission’s (SRTM) Water Body Dataset (SWBD) (Areas between 60° S to 60° N); 2. The MOD44C, a non-public, 250 m global 16-day composite collection based on 8+ years of Terra MODIS data, and 6+ years of Aqua MODIS data. This data set originally provided the input to produce the Vegetative Cover Conversion, and Vegetative Continuous Fields products (Areas between 60° N to 90° N); and 3. The MODIS–based Mosaic of Antarctica (MOA), which is a 250 m MODIS level-1b mosaic for Antarctica (Areas within Antarctica between 60° S and 90° S). Other appropriate and publicly available data sets were also used to supplement the production of the MODIS 250 m land–water mask. Additional details regarding the methodology are available in the User Guide. This marks the first time that such a global MODIS-SRTM land-water mask is offered publicly to end-users. This data set is provided in the same gridded tile structure that is common to several higher-level MODIS land products.
