ForCS flux re-calculation

[Caren Dymond]

Hello to ForCS users!

Unfortunately we've identified a bug in the log_Summary calculation of fluxes. Here's the work around until we're able to get a new release. Thanks to a diligent Université du Québec en Abitibi-Témiscamingue student for their help!

1. NBP_corrected (Net Biome Production corrected):

NBPcorrected​=ΔStocks=S(t)−S(t−1), where i is the year.   For S(t=0) we don't have the previous value so you can use a regression between NBPcorrected and NBPno-corrected from all other years. Stocks are the sum of bio, DOM and soil stocks.

2. Disturbance (Carbon losses by fire and harvest):

D=NEPno-corrected​−NBPno-corrected​

3. NEP_corrected (Net Ecosystem Production corrected):

NEPcorrected​= NBPcorrected ​+D

4. NPP_corrected (Net Primary Production corrected):

NPPcorrected​=NEPcorrected  +Rh

5. Net Growth corrected

Net Growth=NPPcorrected​-Turnover

Please reach out if you have any questions or concerns.

thanks

Caren
