2021-09-21Terra spacecraft is expected to exit the EOS Morning Constellation by October, 2022. All instruments including MODIS on-board the spacecraft are expected to acquire earth view data and SIPS produce science quality data through Fall of 2025. Learn more 2021-08-05S-NPP is back to mission pointing as of 22:28 UTC, August 3 and all instruments have been recovered. Learn more 2021-08-03S-NPP spacecraft is in safe mode and all science data acquisition disabled since 12:46 UTC, August 3 2021. Learn more The Terra day/night acquisition is now following a flexible scheduling, allowing for alternate coverage of the poles. This is an improvement over the fixed 44.2/55.8 day/night coverage that was being followed immediately after the Terra PWA failure. Learn more MODIS Land C61 reprocessing is currently in progress at MODAPS. C61 land products from the on-going reprocessing could be available to public from NASA DAAC by end of December 2020. Learn more MODAPS has started filling the gap over the Aqua FMU anomaly period, using limited coverage from different DB stations. Learn more MODIS Terra day/night coverage ratio has been changed from the existing 50/50 to 44.2/55.8, to reduce the chance of unrecoverable data losses, following failure of another Terra onboard Printed Wire Assemblies (PWA) or memory boards that was designated for MODIS. Learn more 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. Learn more 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. Learn more 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. Learn more 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 NTSGThe S-NPP and J1/N20 V2 re-processing at NASA Land SIPS is about to begin in a few months. Learn more Users are requested to make a note that certain L2 active fire products from current V1 processing of S-NPP in AS 5000 may be unusable. Learn more V1 reprocessing and forward processing of the VIIRS Surface Reflectance suite of products (VNP09) is in progress in AS 5000. Reprocessing started with processing of Jan 2015 and forward processing started at day 2016188 (7/6/2016). Reprocessing stream will shift to the beginning of mission (1/19/2012) after the ongoing reprocessing completes through day 2017187. Moderate and Image resolution fire products (VNP14) are also being generated in both streams.Forward processing of VIIRS Land data products in AS 3002 was stopped on day 196 (07/14/2016). Products slated for permanent archive in AS 3002/3001 are still available from LAADS.SNPP VIIRS Land Records from C1.1 reprocessing using best of Calibration LUTs and science algorithms available from AS 3110. This reprocessing contains records for the mission period Jan 2012 - Jan 2016.Data products from the early mission period were labeled as of BETA quality. Many products have now reached maturity stage of "provisional quality" or "Validation Stage 1".
