Problematic data of Global MODIS and FLUXNET-derived Daily Gross Primary Production, V2

by ptxyzs » Fri Mar 08, 2024 9:20 am America/New_York

I am working on "Global MODIS and FLUXNET-derived Daily Gross Primary Production, V2" dataset (https://daac.ornl.gov/cgi-bin/dsviewer.pl?ds_id=1835).

When processing this, I found the "GPP_FluxSat_daily_v2_200106.nc4" data shooting error of not able to initialize dimension variable time. Data cannot be opened by panoply, ncview, python, R... It turns out there are several NaN values included in the 'time' variable. All platforms we can get accessed to share the same problematic data.

I wonder if anyone would take care of this and upload the fixed data (asap)?

Hi @ptxyzs ,

Could you please redownload file GPP_FluxSat_daily_v2_200106.nc4 from https://doi.org/10.3334/ORNLDAAC/1835? The time values should have been fixed. But please let us know if you still see issues. Thanks!
