Wind Resource File - Kauai

Hello, 
I would like to use the SAM Wind Model for Kauai, HI.  However, the Wind Resource File download tool does not find anything for Hawaii.  
Could someone point me in the right direction for how to go about obtaining a Wind Resource File for this area?
Thanks!
John

Hi John,

You can use NREL's WIND Toolkit API to download offshore wind resource data for Hawaii:

developer.nrel.gov/docs/wind/wind-toolkit/

The Download button on SAM's Wind Resource page accesses the wtk-download dataset, which does not include the offshore Hawaii data.

There may be other sources of data that I am not aware of.

Best regards,
Paul.

Thank you, Paul.   I am new to this whole process of working with an API...steep learning curve!
I am trying to get the first example GET command at developer.nrel.gov/docs/wind/wind-toolkit/offshore-hawaii-download/#examples to work.
 
I got ChatGPT to convert the command to Python
I changed the email in the code to mine.

That gives me the Python code below.  I put it in a file and ran it using Python3 on my Mac.  It generates a 404 error.
The one thing that sticks out to me is that there is no actual HTTP address for the url, it's just a path.

If you have any insight on what I should enter for the server address, (or any other advice) I would be grateful!

if response.status_code == 200:
    data = response.json()  # Assuming the response is in JSON format
    # Process the data as needed
else:
    print(f"Request failed with status code {response.status_code}")


 

Hi John,

You might try constructing a URL to make the request before diving into Python. The example toward the bottom of the API documentation page is a good starting point. You can add " developer.nrel.gov " to the beginning of the example that starts with "api/wind-toolkit/...", and change the email address and key to yours.

You can then paste the URL into your browser, and you'll either get the file you requested or a JSON response with an error message.

Once you have a URL that works, you can then try to get things working in Python.

Best regards
Paul.

The different WIND Toolkit API endpoints return data in different text formats. The format SAM recognizes is returned by the following endpoints: 

The following, including the Hawaii offshore one use a different format: 

The "SAM CSV Format for Wind" topic in SAM's Help system describes the format:  samrepo.nrelcloud.org/help/weather_format_csv_wind.htm  

You should be able to edit the Hawaii file or others from the endpoints with the different format to work with SAM.  

Best regards,
Paul.
