PACE OCI data unavailable via opendap

by mikejmnez » Thu Feb 26, 2026 4:47 pm America/New_York

Hi,

I am able to retrieve the opendap urls from the CMR. For example:

https://oceandata.sci.gsfc.nasa.gov/opendap/PACE_OCI/L3SMI/2024/1202/PACE_OCI.20241202_20250102.L3m.R32.CHL.V3_1.chlor_a.4km.nc

or a newer:

https://oceandata.sci.gsfc.nasa.gov/opendap/PACE_OCI/L3SMI/2025/0602/PACE_OCI.20250602.L3m.DAY.CHL.V3_1.chlor_a.4km.nc

But I cannot access any data/metadata. For example if I try to read the metadata using python's requests (.netrc is correctly accessible in my machine)

```python
my_session.get(url+".dmr")
>>>
ConnectionError: ('Connection aborted.', ConnectionResetError(104, 'Connection reset by peer'))
```
I also get a "The connection to oceandata.sci.gsfc.nasa.gov was interrupted while the page was loading." when trying to access the opendap page for any opendap PACE OCI url.

Thanks!

Hello, Please update your code to choose 'dmr.html' or '.dmr.xml' and let us know if that works.

Thanks! It is working now!
PS - appending ".dmr" should always redirect to ".dmr.html", so no need to update any code/snippet. Glad it is working now. :)

No, no...thank YOU. ;)

Our server did encounter an issue for a short while yesterday. It appears that what you actually encountered. Thanks for confirming it's working now.
