Forecasts and data recorded by most public weather data providers (such as Met Office) are measured at a height of 10 meters.
➡️ Met Office datasets
⚠️ We invite you to inquire about the data collection conditions of the platform you are comparing your Windcrop data with.
If you have followed our installation recommendations to be as close as possible to what is happening in your fields, your Windcrop station is located at a height of 2 meters.
Wind Speed Conversion
Using a wind data converter
You can use a converter to check the equivalence between the data collected at more than 2 meters and that of your Windcrop.
To do this, you will need to:
Convert the speed from km/h to m/s.
2. Use a converter that takes into account the data collection height.
Enter the following parameters:
Height (your anemometer's height) | 2 |
Wind speed | Speed recorded by your anemometer |
Roughness z0 | Refer to the table (bottom of the page) |
You will get a table with results at different heights (starting from 10m).
Example
For a wind gust measured at 50 km/h at two meters high:
| km/h | m/s |
10m high | 76.9 | 21.37 |
2m high | 50 | 13.9 |
