    Welcome to the MODIS Land
    Quality Assessment Site

         Quality assessment (QA) is an integral part of the MODIS Land production chain. The objective of MODLAND QA is to evaluate and document the scientific quality of the MODLAND products with respect to their intended performance. The results of MODLAND QA are made available on a routine basis and are formally stored as product metadata and as per-pixel information. MODLAND QA results are also placed on the Product Quality web pages located at this site. Users are encouraged to check these QA results when they order and use individual products to ensure that they were generated without error or artifacts.


    What is New!

    • Collection 5 reprocessing is in progress. Reprocessed data are now available at DAAC.
    • Land data can now be ordered through global browse web site.
    • New inter-comparison time series plots for year 2005 are available now.
