MODIS Version 6.1 Surface Reflectance Data Products are Available!

The Land Processes Distributed Active Archive Center (LP DAAC) is pleased to announce the release of Moderate Resolution Imaging Spectroradiometer (MODIS) Version 6.1 land data products. The release begins with Surface Reflectance data products followed by the Land Surface Temperature and 3-Band Emissivity product suite. The volume of MODIS Version 6.1 data will continue to grow as historical and forward processing is completed.

Improvements for Version 6.1 data products include changes and enhancements to the Terra and Aqua MODIS L1B products used as inputs to the higher level products.

• The Version 6.1 Level-1B (L1B) products have been improved by undergoing various calibration changes that include: changes to the response-versus-scan angle (RVS) approach that affects reflectance bands for Aqua and Terra MODIS, corrections to adjust for the optical crosstalk in Terra MODIS infrared (IR) bands, and corrections to the Terra MODIS forward look-up table (LUT) update for the period 2012 - 2017.
• A polarization correction has been applied to the L1B Reflective Solar Bands (RSB).

Details on product improvements for Version 6.1 will be provided on the Digital Object Identifier (DOI) landing page for each product. Version 6 data products will remain available and will continue with forward processing during the transition.
