History & Climate Data
This page provides information about retrievable variables and variable-specific input parameters, as well as climate data packages.
Further information can be found in the following places:
- Input and output parameters of the History API are listed on the overview page
- Detailed information about weather variables can be found in the weather variable specification
Weather Variables
One API call retrieves data for one weather variable. Some weather variables need additional parameter settings in the API-URL (see column "Additional mandatory parameters"). The API supports various units, which may be specified in the API request (see Weather Variable Units).

Climate Wind Rose
The Climate Wind Rose data package contains historical data of wind speed and direction over 30 years, and describes how many hours per year the wind blows from the indicated direction and at the indicated speed. The data is accumulated from 30 years of historical weather simulation data from the global meteoblue model NEMSGLOBAL, which has a resolution of 30km.
Example SW: Wind is blowing from South-West (SW) to North-East (NE).
