Moderate Resolution Imaging Spectroradiometer (MODIS) Irrigated Agriculture Dataset for the United States (MIrAD-US)

We have employed a geospatial modeling approach implemented for three time periods (2002, 2007 and 2012) to consistently map irrigated agriculture across the conterminous U.S. (Brown and Pervez 2014; Pervez and Brown 2010; Brown et al. 2009). Model inputs included the National Land Cover Dataset resampled to 250m, USDA Census of Agriculture irrigated area statistics, and annual maximum vegetation index (VI) calculated from NASA Moderate Resolution Imaging Spectroradiometer (MODIS) imagery. These data can be used to help assess water-quality trends in ground and surface waters, explain drought impacts on vegetation, and support the application and refinement of current water volumes used for irrigation.

Notice to Users:

Version 3 of the MODIS Irrigated Agriculture Dataset for the United States has now been released. In this version, consistent input data and processing procedures were used for each historical era (2002, 2007, and 2012) resulting in improved standardization. (Date: 04/16/2015)
