Version: SAM 2023.12.17 r1

I downloaded the recently added Offshore South Atlantic data for  -75.491638 36.896313 and used this to load wind resources (see attached). After filling out other tabs, hitting "Simulate" resulted in the following;

```
exec fail(windpower): error reading wind resource file for interpolation at time step 0: 
Simulation windpower failed :This weather file appears to contain a leap day. Feb 29th will be skipped. If this is not the case, please check your wind resource file.
```
Note: I had to add in -5 to the data time zone, which came blank

Is this new wind data in the right format?

Hi WillStewart,

A description of the "SAM CSV Format for Wind" is here: samrepo.nrelcloud.org/help/weather_format_csv_wind.html .

To fix your file:
  • Change the file name from .srw to .csv so SAM will recognize it.
  • Remove the rows for February 29 to avoid the error about leap day.
  • SAM's wind power model requires atmospheric pressure data, which is missing from your file.
Best regards,
Paul.
