### Observed climate

#### Indicators:

- Monthly mean precipitation
- Monthly mean temperature

  | #### Monthly mean precipitation
  | unit: mm/month dimension: month

  The monthly mean precipitation is taken from a gridded climatology database by for the climatic normal period of 1961-1990. They have collected weather-station data from all over the world and interpolated the monthly precipitation data using an innovative approach to correct for local differences in elevation between stations.

  We use this database as our baseline climatology for the precipitation patterns on which the precipitation change is overlaid.

  The climatic patterns are used in the terrestrial vegetation model to calculate vegetation and crop patterns and productivities, in the terrestrial carbon model to calculate the different carbon fluxes, and in the land-use emissions model to calculate emissions.
