Dataset description

*** 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.

Questions before production use

Practical answers on evaluation, licensing, freshness, versioning and support.

api.store is built and operated by Apitalks s.r.o. Company details and a direct contact path are linked in the footer for vendor checks and procurement review.
Yes. Selected APIs include a free API quota, so your team can validate coverage, freshness, response shape and workflow fit before asking for a production plan.
Often yes, but usage rights depend on the source license and dataset. We surface source, license and update metadata where available, and can help review terms before a production integration.
Maintained APIs include update metadata where available. For production integrations, we can add history, monitoring and push updates so changes are easier to detect and act on.
Production APIs can add SLA, stable identifiers, versioning support, history, push updates and direct support around the data your product or AI workflow depends on.
