Re: Missing MOD11A2.061 tiles from 2001

Hi Mauricio,
Thanks for your patience. The CMR cloud library has been updated so it should be reconciled with our on-prem Data Pool.

Re: Error loading into memory HLS data

Hi Charlie, We've updated the HLS_Tutorial.ipynb to include a try loop around reading of the HLS files via https. There seems to be some sort of network issue that can cause that error, and it appears to be independent of the code being executed in the notebook. We would recommend adding a retry loo...

Question: MODIS band 6, or LSWI, at 250m resolution?

Re: MODIS band 6, or LSWI, at 250m resolution?

Hi Tim,
Unfortunately I am not aware of any entity that has resampled the 500 meter data to 250. MODIS Bands 1 and 2 are the only 250 meter bands and bands 3-7 are 500 and 8-36 are 1000 meters. WIsh I could be of more help.
Thanks,
Brett

Re: Problems downloading VNP15A2H v002 vegetation products

Hi Enrique, Yes, that is a good idea and that is in the works. Right now the data base administrators are accessing what is all missing. It varies with each product. The data providers are not giving us any timeline, as I don't think they have any idea at this point. Thanks for your patience. Brett

Re: Problems downloading VNP15A2H v002 vegetation products

Hi Enrique,
Sorry for the delay with the V002 processing. The data providers have been made aware of this and we are trying to reconcile the discrepancies and fill in the gaps. Unfortunately, we do not have a firm timeline on when this will be complete. Thanks for your patience.
