Project CAMS41 Phase 2
Optimization of CH4 wetland emissions in CTESSEL model using FLUXNET-CH4 dataset

All site simulations are done with the same CTESSEL configuration:

The 44 sites are selected out of the total number of 72, showing the optimization improvement on the single-site level.

With the selected sites the multiple-site optimization is performed, grouping the sites by:

In multiple-site optimization one pair of parameters per group is optimized: s (scaling factor) and Q10 (temperature dependency factor)

The best performance is obtained by optimizing with the TYPE grouping, the results are summarized below:
