The Land Processes Distributed Active Archive Center (LP DAAC) decommissioned the Terra MODIS Net Primary Production Yearly L4 Global 1 km SIN Grid (MOD17HA3) data product on April 6, 2020. This annual product is no longer distributed by the LP DAAC or available for download from NASA’s Earthdata Se...

We recently received a question from a user that we think others in the community might be wondering about too:
Why is there no 8day data for MOD17A3?

Hi,
I am not sure how you are attempting to access the data. However, the following URL is where the data resides on the Data Pool. Please try this route and if it is still not working let us know: https://e4ftl01.cr.usgs.gov/MEASURES/GFSAD30SAAFGIRCE.001/2013.01.01/

Thanks,

Hi Julia,
Sorry for the delay. There was a issue with a maneuver primarily on September 3 and 4. The data providers were able to recover the data and is has since been processed. If you have not tried recently to access the data, please do. Thanks for your patience.

Hi,

Thanks,

Hi Val, Sorry for the issues accessing the VIIRS product. Unfortunately, the VIIRS Version 2 products will not be available in the Data Pool. The LPDAAC is transitioning away from on-prem data and eventually all our data will be in the cloud exclusively. The Earthdata Search tool is the primary inte...

Hi Jeongho,
I am thinking those specific pixels are of questionable quality. Did you have a chance to look at the QA information for those pixels? If you could send me a specific Granule ID with the H/V number and date I could take a look and see what may be going on.
Thanks,
Brett

Hi Niklas, Sorry for the delay. We contacted the Science Team and the product developers on the corruption issues. Technically they don't consider it corrupted as much as the inability and challenges of the sensor to acquire data in the very high latitudes. They said: "the light blue area is ei...
