Introduction
Motivation:
- Evaluation of CTESSEL model fluxes from diurnal/synoptic/seasonal.
- Attribution of biogenic flux correction into GPP and Reco
SIF linear operator
Extending BFAS with SIF
BFAS-SIF GPP/Reco correction coefficients and resulting budgets
IFS CO2 experiments
IFS CO2 experiments have been performed with resolution tco399 (~25km) L137.
| Experiment ID | Description | Period |
