MODIS (Moderate Resolution Imaging Spectroradiometer) sensor data are highly useful for field research. However, the volume of MODIS data and the complexity in data format makes MODIS data less usable in some cases. To solve this usability issue, the Oak Ridge National Laboratory (ORNL) Distributed Active Archive Center (DAAC) prepares and distributes subsets of selected Land Products in a scale and format useful for field researchers. MODIS subsets are provided for more than 1,000 sites across the globe. The subsets are offered in tabular ASCII format and in GIS compatible GeoTIFF format. Time series plots and grid visualizations to help characterize field sites are also provided. In addition to offering subsets for fixed sites, the ORNL DAAC also offers the capability to create user-defined subsets for any location worldwide. The MODIS Global subsetting tool provides subsets from a single pixel up to 201x201 km for user-defined time range. Statistics, time series plots and GIS compatible files for the customized subsets are also distributed through this tool. Users place an order for a MODIS subset online and an email is generated when the subset is created.
