The ORNL In-Situ and Satellite Information System (ISIS) provides time-series charting of land surface data products from select field sites in North America. This tool uses Open-source Project for a Network Network Data Access Protocol (OPeNDAP) and Simple Object Access Protocol (SOAP) technologies to integrate diverse data products from distributed sources for both site and satellite-based products including:

• site- and satellite-based
• Land Surface Temperature (LST)
• Calclated Albedo
• Normalized Difference Vegetation Index (NDVI)
• Gross Primary Productivity (NPP)
• satellite-based
• Leaf Area Index (LAI)
• Enhanced Vegetation Index (EVI)

Access to the following Moderate Resolution Imaging Spectroradiometer (MODIS) Land satellite products is provided:

• MOD11A2 LST
• MOD13Q1 NDVI and EVI
• MOD15A2 LAI
• MOD17A2 GPP
• MCD43A1 Calculated Blue Sky Albedo
• MOD04, MYD04, and MOD08 aerosol optical depth data

For the following data site-based resources:

• 51 AmeriFlux sites (level 2 data)
• 103 La Thuile FLUXNET 2007 Synthesis Sites
• 68 U.S. Climate Reference Network (USCRN) sites

Note that not all products are available for all sites.
