 MODIS Level 1 and atmosphere products are available through the Level 1 and Atmospheric Archive and Distribution System ( LAADS). [[http://​ladsweb.nascom.nasa.gov/​]] ​ Level 1 products include raw radiance and calibrated radiance images. Raw digital number images are also available through order. All of the images in their archive are free of charge. ​ MODIS Level 1 and atmosphere products are available through the Level 1 and Atmospheric Archive and Distribution System ( LAADS).

-Level 2 and 3 Land Products are available through Nasa’s Warehouse Inventory Search Too (WIST) and the Land Processes Distributed Active Archive Center (LPDAAC) Data Pool at the U. S. Geological Survey EROS Data Center (EDC). https://​lpdaac.usgs.gov/lpdaac/​get_data ​ Examples of level 2 and 3 products are land cover, leaf area index, surface temperature,​ and burned area. All products on a specific temporal schedule are archived and available free of charge to the general public. Detailed instructions on how to acquire MODIS  data through the LPDAAC Data Pool are here: [[https://​lpdaac.usgs.gov/​lpdaac/media/files/data_pool_tutorial_pdf]].+Level 2 and 3 Land Products are available through Nasa’s Warehouse Inventory Search Too (WIST) and the Land Processes Distributed Active Archive Center (LPDAAC) Data Pool at the U.

-Another source for MODIS data is the Global Land Cover Facility. [[http://​www.landcover.org/​data/​modis]] They offer several vegetation products ​ made from 16-day and 32-day composite images. The products come in a GeoTIFF format which can be easier to work with in a geographic information system.+Another source for MODIS data is the Global Land Cover Facility.

 ===== Image Format ===== ===== Image Format =====
-MODIS data from NASA/USGS are distributed in the Hierarchical Data Format (HDF-EOS). This format can be reprojected or converted into other formats such as GeoTiff, but in the past HDF-EOS has been notoriously difficult to work with. Recent versions of ArcGIS (e.g., version 9.3) can read the HDF-EOS format. A listing of some other tools that can be used to view and convert HDF-EOS images can be found at [[https://​lpdaac.usgs.gov/lpdaac/tools]], but be cautioned that most of these tools are not easy to implement.+MODIS data from NASA/USGS are distributed in the Hierarchical Data Format (HDF-EOS).
