Weather File Downloads Issue

Did NSRDB go down? I cannot access files to use in SAM right now. I'll try again tomorrow, but I thought I would post to see if a bigger change is in progress.

I've tried downloading by location (Lexington, KY) and lat/lon.

I get the following error in SAM logs:
NSRDB Download Thu May 22 14:30:34 2025
==========================================================

Requested location(s): [ -84.5003, 38.0486 ]

Location 1 of 1: "-84.5003, 38.0486"

"-84.5003, 38.0486" appears to be a valid lat/lon pair in Decimal Degrees.

Latitude / longitude for NSRDB Data Query: -84.5003,38.0486

URL for NSRDB Data Query: developer.nrel.gov/api/nsrdb/v2/solar/nsrdb-data-query.json?&api_key= &email=&wkt=POINT(38.0486%20-84.5003)

NSRDB Data Query returns no data for "-84.5003,38.0486" (outputs = []).

See sam.nrel.gov/weather for links to other data sources.

I've also tried going to the NSRDB viewer and I get an error email that no data is available much later.
I also tried using the Python SDK and nsrdbfetcher.
nsrdbfetcher = tools.FetchResourceFiles(
                tech='solar',
                nrel_api_key=sam_api_key,
                nrel_api_email=sam_email, 
                resource_type='psm3-2-2', 
                resource_year='2021')
lon_lats = [(-84.5003, 38.0486)]
nsrdbfetcher.fetch(lon_lats)

It did not work and replied with:

{'inputs': {'body': {}, 'params': {}, 'query': {'names': '2021', 'wkt': 'POINT(-84.5003 38.0486)', 'interval': '60', 'email': 'joe.dvorak@uky.edu', 'utc': 'false'}}, 'metadata': {'version': '2.0.0'}, 'status': 400, 'errors': }
 

Hi Joseph,

The NSRDB service may have been temporarily down yesterday. Weather file downloads from SAM are working today.

Note that if you submit a latitude-longtiude pair in SAM, you should put the latitude first, so you would type "38.0486,-84.5003" for your location.

Best regards,
Paul.
