TRENDYv10 DGVM output for: Process-oriented analysis of dominant sources of uncertainty in the land carbon sink

*** SEE VERSION 3 FOR NCDF FILES ***

Data

Post-processed TRENDYv10 DGVM data covering the period 1901-2020. Each file contains monthly/annual mean values for 19 models: CABLE-POP, CLASSIC, CLASSIC-N, CLM5.0, DLEM, IBIS, ISAM, ISBA-CTRIP, JSBACH, JULES-ES-1.1, LPJ-GUESS, LPJ, LPX-Bern, OCN, ORCHIDEE, ORCHIDEEv3, SDGVM, VISIT, YIBs. See https://blogs.exeter.ac.uk/trendy/

List of variables can be found at https://blogs.exeter.ac.uk/trendy/documents/ . File name: 'trendy_listofvariables_GCP2021'.

Data for three experiments (S1 - S3) is provided. For experiment details, see 'GlobalCarbonBudget-Protocol-2021-web' at https://blogs.exeter.ac.uk/trendy/documents/

Global, regional, and gridded values are provided.

Global mean files are named "variable_experiment.RData". Structure = [time,models]=[120,19]. Flux units = PgC/yr, stock units = PgC.

Regional mean files are named as "variable_experiment_2lats.RData" and contain values for 2 regions; northern lands (>30N) and tropics/southern lands (<30N). Structure = [region,time,models]. For fluxes (gpp, nbp, npp, rh), files contain two variables: 1) "variable_experiment" (structure=[2,1440,19]) and 2) "variable_experiment_annual" (structure=[2,120,19]). Variable 1 contains monthly mean data and variable 2 contains annual mean. Units for regional fluxes are kgC/m2/s. For stocks (cCwd, cLitter, cSoil, cVeg), files contain annual mean values only [2,120,19]. Units for regional stocks are PgC.

Gridded files are named as "variable_grid_experiment_annual.RData" and contain annual mean values for each land grid point, year, and model. Structure is [lon,lat,time,models]=[360,180,120,19]. Flux units = kgC/m2/s, stock units = kgC.

Code

All data processing code is also provided. Files starting "raw#..." are run in order 1-4. Then the figure/manuscript files are executed, starting with "proc1.." - "proc3..". The remaining Figure scripts (Figures 1-5 and S1-S8) and "temp_changes.R" can be run in any order.
