@dpatil-fw Thank you so much for reporting this issue. It seems that the downloaded HDF5 file might be corrupted. I'll have to investigate further.

[dpatil-fw]

Sure. Found your work and all the documentation, very helpful. Thanks a lot!

I am facing this issue as well. I followed the steps in the documentation and faced the same error reported here.

Any updates on this ?

Hi! I was facing the same issue as well.

But when I tried to download the blackmarble HDF5 file manually from this website: NASA blackmarble manual download

It prompts me to fill out my "Affiliation" information on my Earthdata login profile.

After filling out the required affiliation information, now I can download the HDF5 properly, and this error has disappeared.

It seems our TOKEN to access the API will not be valid, unless if we fill out the required "Affiliation" information on our Earthdata profile.

I hope it helps!

@mashafif Thank you so much for your contribution! @aizadyar23 @cygniv404 Could you please check if the "Affiliation" might be missing and confirm if filling it out solves the issue?
