  What's New!

  • The C6 year-end gap-filled versions of M*D16 and M*D17 8-day and annual products are now operational from MODAPS. These offer better science quality than the M*D16 and M*D17 products from regular production and users are advised to switch to these products, that are produced from NTSG. The NTSG equivalents are only available till 2014 and will be decommissioned in the near future.
  • C6.1 re-processing of L1B and Atmosphere products is now fully complete and C61 re-processing of Land is expected to start around June/July of 2019. For further details of the C61 Land re-processing plan please click here
  • C6 re-processing of all Land products are complete and all current C6 land products are at leading edge.
  • Annual MOD17A3H/MYD17A3H and MOD16A3H/MYD16A3H from the operational C6 processing has been discontinued because of irregular retrieval issues and users are advised not to use this data, even if they had downloaded this data earlier from LP-DAAC. Instead, MODAPS will introduce better gap-filled year end M*D16A3GF and M*D17A3GF products soon as part of collection 6 products. For immediate use, the users are advised to use the Annual MOD16/MOD17 products from NTSG: https://www.ntsg.umt.edu/project/modis/

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.
