Missing tiles for historical MODIS data

[martinkeller]

Hi All,

I am trying to download historical MODIS NDVI data for India and I noticed that a lot of historical data doesn't seem to be available. In particular, before June 2022 only a few number of tiles for the MOD13Q1 and MYD13Q1 data products are available.
The particular tiles that I'm trying to access are 'h24v05', 'h24v06', 'h25v06', 'h26v06', 'h24v07', 'h25v07', 'h26v07', and 'h25v08'; only information for tile 'h25v08' is available.

Could you please let me know if this data is no longer available for download or if this a temporary outage?

Best regards,

Martin Keller

Hi @martinkeller We are looking into this but so far everything looks normal from before June 2022. Could you please a) try again and b) if you are still seeing missing data for these granules let us know a few specific dates? Thanks -- Danielle

I just tried to download the data for DOY A2022129. I again requested the tiles 'h24v05', 'h24v06', 'h25v06', 'h26v06', 'h24v07', 'h25v07', 'h26v07', 'h25v08', but only got 'h24v05'.

Just to rule this out, just in case, if you were expecting MYD13Q1 data that day, there would be no data over your area on 2022129 due to the temporal resolution of the data (16 day). The area would have MYD13Q1 data for 2022121 and 2022137.
