Project CAMS41 Phase 2
Optimization of the Farquhar photosynthesis CTESSEL module using the FLUXNET2015 dataset (preliminary)

Select PFT: General information PFT1 (Crops, mixed farming, C4) PFT2 (Short grass, C3) PFT3 (Evergreen needleleaf, C3) PFT5 (Deciduous broadleaf, C3) PFT6 (Evergreen broadleaf, C3) PFT7 (Tall grass, C4) PFT9 (Tundra, C3) PFT10 (Irrigated crops, C3) PFT11 (Semidesert, C4) PFT13 (Bogs and marshes, C3) PFT16 (Evergreen shrubs, C4) PFT17 (Deciduous shrubs, C3) PFT18 (Mixed forest - Wood, C3)

Optimization configurations

1. Posterior1:
• standard CTESSEL code as distributed to ECMWF
• computation time limited to 72 hours
2. Posterior2:
• same as 1
• co2 downregulation off
• acclimation off (acclimation terms for S_Jmax, S_Vcmax and vj are replaced with the fixed growth temperature of 20°C)
• variation range for KHUMREL increased from [0.7 - 1.3] to [0.5 - 2.0]
• variation range for VCMAX for PFT7 and PFT16 increased from [30 - 70] to [30 - 80]
3. Posterior2b (only for PFT5):
• same as 2
• variation range for KHUMREL set back to [0.7 - 1.3]
4. Posterior3:
• CTESSEL code from ECMWF (variables renamed to CTESSEL conventions, adjusted acclimation)
• optimization code v2 (with optimized parameter values passed through namelist)
• variation range for KHUMREL increased to [0.5 - 4.0]
