The (re)calibration of crops for WOFOST and LINGRA are performed using different calibration tools and agropheno datasets.
- WOFOST control centre: user interface to run wofost crop model and interactive selection of crop-, soil-, weather-files. Changes interactively model parameters. Analyse results in table and graphical format. Used for manually local calibrations.
- Calplat. Optimization platform to create zonations and execute automatic calibrations.
- Calibration Manager. Python script that combines Python wofost with open optimizer NLopt to automatically calibrate multiple zones and multiple parameters.

The calibration consist in the following subtasks:
- Consistency check of the datasets (area of interest, make decisions how to calibrate the models and which part of the DBs to exploit).
- Coherent recalibration from EU15 to EU25 with the results of the consistency check of the existing crops.
- Calibration of new crops at EU25 level. This includes verifications of the consistency of the CGMS output by runnin simulations up to level 3 in order to verify the output obtained using the new crop parameters.
- Validation with sub data sets.
The calibration and the validation can be done according to one of the following strategy/approaches based on the data availability:
- Strong: Based on complete sets of crop parameters from experimental fields.
- Medium: Based exploiting as much as possible the crop parameters data available in the DBs.
- Light: Based on TSUM derived from CGMS level 1 and basic crop calendars. As the information of crop start-emergence/flowering/end-of-maturity at grid level are the basic information available in the system, the main tables which are analyzed are the WEATHER_OBS_GRID and the WEATHER_OBS_GRID_LTA to relate meteo data with calendar day to calculate crop TSUM.
