Summary
Abstract: This dataset represents spatial aggregates of the MODIS/Terra Surface Reflectance 8-Day L3 Global 500m ISIN Grid (MOD09A1), as provided by the EROS Data Center (EDC). THis product is available for multiple days.

The University of New Hampshire's (UNH) Earth Science Information Partner (ESIP), EOS-WEBSTER (http://eos-earthdata.sr.unh.edu/), has created this MODIS surface reflectance aggregate product from MOD09A1 8-day 500m surface reflectance tiles. MOD09A1 data are provided every 8 days as a gridded level-3 product in the Integerized Sinusoidal projection. UNH has aggregated multiple tiles to create a large-region surface reflectance product, which can be spatially subset within the EOS-WEBSTER Search & Retrieve data ordering tool. Our system has also reprojected these data from the original Integerized Sinusoidal projection to Geographic, with a pixel resolution of 15 arc seconds.

The aggregate products contain all the layers from the original input products plus an additional layer created by EOS-WEBSTER, which provides a look-up code to map each pixel in the aggregate back to its original input tile.

These aggregate products allow the users of EOS-WEBSTER to subset MODIS 8-day surface reflectance data across tile boundaries and to customize the spatial region of interest using an on-line GUI interface. Data are also provided in a generic binary format (BSQ) with detailed header information, which can be read into most image or data processing applications. EOS-WEBSTER has broken the original 12 layers in the input tiles into 6 logical holdings so that a user may order 1 or more of the band sets (see below). For instance, the user may only wish to order the 7 reflectance bands and not all the other supporting data which are provided with the original data-this significantly cuts down on the data volume.

Version-4 input products were used to create these output files. Please see the Global Change Master Directory (GCMD) to learn more about the MOD09A1 input data (http://gcmd.nasa.gov/getdif.htm?MOD09A13).

This MODIS surface reflectance product may be used to generate land- related products or used as input to global and regional climate models and surface energy balance models. These data also may be used for land cover characterization.
