Different forecast results.
-
Does anyone know why every time I run a wind speed forecast using a GFS model I get different results?
I am obtaining the wind speed at 150m at lat=40.05 and lon=-7.68.
I attach some pictures of the results I am getting.

@rodrigo-67 Hello, could you please describe what source are you using? Are you comparing it with Windy?
-
@korina The green data comes from on-site recorded wind speed measurements, and the orange data is from the windy forecast.
Every time I request a forecast through the API I got different results. I am using the following parameters for the json body:
body = {
"lat": 40.05,
"lon": -7.68,
"model": "gfs",
"parameters": ["wind", "pressure"],
"levels": ["surface", "150h"],
"key": api_key

@rodrigo-67 Hello, we visualize forecast, not real-time data, also the outcome depends may differ based on the model.
If you are not using the paid version of API, then we the API returns random coordinates.
-
@korina Yes I understand. I just wanted to plot measurements (in green) and your forecast (in orange) for future comparison.
So does that mean that I have to use the paid version of the API to get an accurate forecast? Meaning that with the free version I will get a forecast for random coordinates?

@rodrigo-67 Yes, Point Forecast Trial returns modified data as explained here - https://api.windy.com/point-forecast
