General description
The calibration of crops for WOFOST and LINGRA are performed using different calibration tools and agropheno datasets.
Tools
- 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.
Data sets
The agropheno data are stored in a relational database that contains observations from experimental sites, expert knowledge and regional calendars with their metadata. The metadata can be used to select sources or types of data to be included in the calibration. XY locations of experimental sites and regional calendars are mapped to grid numbers of the regular target agro climatic grids that are defined for each regional window.
The database contains the following data sets:

Calibration levels
The following calibration levels are identified for regional and local calibrations. Each calibration always start with the first level, optionally followed by 2 or 3 and 4.
They are executed in this order, gradually further optimizing results:
Level | Regional | Local |
---|---|---|
1: Phenology | TSUM1, TSUM2 | TSUMEM, TBASEM, TSUM1, TSUM2, DLO, DLC, TEFFMX |
2: Potential yield level - simple | AMAXTB | AMAXTB, SLATB, SPAN |
3: Potential yield level - complex | SLATB, SPAN, FOTB | AMAXTB, SLATB, SPAN, RGRLAI, LAIEM, TDWI, FLTB, FRTB, FOTB, TMPFTB, RDRRTB |
4: Water limited yield level | CFET, RDMCR | CFET, RDMCR, PERDL, DEPNR |
Required agropheno data for the respected levels and resolutions:
Level | Regional | Local |
---|---|---|
1: Phenology | Regional calendars or observations of sowing, emergence, flowering, maturity and harvest | observations of sowing, emergence, flowering, maturity and harvest for different years |
2: Potential yield level - simple | Observations of total biomass under optimal conditions for locations or regions | observations of LAI-max and total biomass under optimal conditions |
3: Potential yield level - complex | Observations of LAI-max, total biomass, storage organs and/or harvest index under optimal conditions for locations or regions | observations of LAI, total biomass, weights of leaves, stems, storage organs and roots over time during the growth period under optimal conditions |
4: Water limited yield level | Observations of total biomass, storage organs and/or harvest index under rainfed conditions for locations or regions | observations of LAI, total biomass, weights of leaves, stems and storage organs and possibly crop transpiration, evaporation and rooting depth over time during the growth period under water-limited conditions |
Calibration steps
The calibration consist in the following subtasks:
- Consistency check of the datasets (area of interest, agropheno data).
- Select calibration tool
- Create zonation and crop mask
- Add default crop from which to start calibration.
- Calibrate phenology (level 1)
- Analyse calibration results: WRMSE's, TSUM1, TSUM2, TSUM1+TSUM2, TSUM1/TSUM2, outliers
- Optionaly correct input data (e.g. zonation, crop masks, agropheno data or weather data) and restart calibration
- Implement calibrated TSUMS and simulate full archive over full geographic extent
- Calculate metrics (long term average crop simulation characteristics)
- Calculate yield forecast
- Compare metrics and forecast with operational crop
- Validation with sub data sets.
Optionally continue calibration:
- start calibration at the next level (e.g. 2, 3, 4)
- Implement calibrated parameters and simulate full archive over full geographic extent
- Calculate metrics
- Calculate yield forecast
- Compare metrics and forecast with operational crop
- Validation with sub data sets.
