CO only | massive productivity? #127

It comes out in the wash for the DIFF graphs, but seems really high. Does this indicate the total carbon stock in CO nearly triples in the next 30 years? image

Initially (i.e., for the CO run in January), vegc_uptake and soilc_accum were calculated proportionally from Gross primary production (GPP), being the sum of net ecosystem exchange (NEE) and RECO (all autotrophic respiration processes). This was an incorrect approach given as CALAND handles respiration separately from the above two parameters.

For the corrected summary flux estimates (see https://tnc.box.com/s/caxu5xq9kr9lps9bz3wnc4g1yeemi81p and c48ebe8), vegC_update was calculated directly from NEE summary stats, while for soilC_accum, we adopted the summary statistics used in CALAND.
