@AliS-Noaa @aliabdolali

What are your preferred web api to download NDBC data?

Thanks

Hello Saeed, Here are two ways I usually get the NDBC data: https://github.com/NOAA-EMC/WW3-tools/blob/develop/ww3tools/downloadobs/wfetchbuoy.py also this is a good tool as well: https://pypi.org/project/NDBC/ Cheers, *--------------------------------------------------------* *Ali Salimi-Tarazouj, Ph.D.* Physical Scientist, Coastal Engineer Lynker at NOAA/NWS/NCEP/EMC 5830 University Research Court College Park, Maryland, 20740 Office: (202) 964-0965 Mobile: (302) 588-5505

From a correspondence with one of our colleagues:

Near-real-time observations from NWS Fixed Buoys and NWS C-MAN Stations and from many ROOA operated buoys and coastal stations are available on the ndbc.noaa.gov web site.
I don't know if NDBC has an API yet, but one can obtain their obs via HTTPS or DODS/OPeNDAP https://www.ndbc.noaa.gov/docs/ndbc_web_data_guide.pdf
However, I found that someone has written 'ndbc-api' to "parse whitespace-delimited oceanographic and atmospheric data distributed as text files for available time ranges, on a station-by-station basis" (https://pypi.org/project/ndbc-api/). I also found ndbc.py at https://pypi.org/project/NDBC/. I imagine there are many others out there.
