  What's New!

  • The Aqua MODIS suffered a science data outage, starting August 16th, 2020 (2020.229) at 09:26:40, because of a FMU/SSR error, the details of which can be found here. The Aqua Flight Operations Team (FOT) worked closely with the different Instrument Operations Teams (IOTs) to resolve this and was able to recover the FMU/SSR, through a soft-reset on September 2, 21:00. Nominal production of all Aqua specific and Terra+Aqua combined products has resumed in NRT and is expected to resume soon on the C6 forward production OPS stream. More details regarding this can be found here
  • Aqua S/C FMU reset was successfully carried out on the afternoon of September 2, 2020, and Aqua MODIS is now back in science mode. Forward processing of Aqua MODIS at MODAPS and NRT will resume. We will keep you posted on the status of processing of Aqua and combined Terra+Aqua MODIS product for the anomaly period (8/16 - 9/2) using the data collected from DB stations.
  • MODAPS has not received any MODIS Aqua data, starting August 16th, 2020 (2020.229), 09:26, because of a FMU (Formatter-Multiplexer Unit) error. Because of this, no Aqua ephemeris data (GBAD) or science data can be accessed. The Aqua Flight Operations team (FOT) is working with the different IOTs to resolve this. More details can be found here.
  • 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.
