ORCHIDEE model outputs before and after adding three high-latitude shrub PFTs

This dataset contains outputs of the ORCHIDEE land surface model produced for and used in the analyses presented in: Kirchner, A., López-Blanco, E., Bastrikov, V., Luyssaert, S., Peylin, P., and Lansø, A. S. (2026). Introducing shrubs enhances the representation of high-latitude vegetation and carbon cycling in the ORCHIDEE land surface model. EGUsphere preprint. https://doi.org/10.5194/egusphere-2026-1071 This dataset contains outputs of the ORCHIDEE land surface model over the high-latitude region (north of 50°N), run at 2 km x 2 km resolution. The outputs correspond to two different historical simulations (1992-2020): one with a setup of 15 PFTs, and one with 18 PFTs, after adding three high-latitude shrub PFTs, as described in Kirchner et al. (2026). File descriptions: ORCHIDEE_15PFT_19920101_20201231_1M_stomate_history.nc: Outputs of historical simulations (1992-2020) with ORCHIDEE before adding high-latitude shrub PFTs. The outputs are in monthly resolution and include variables such as vegetation cover, plant height and diameter, biomass and carbon fluxes. ORCHIDEE_18PFT_19920101_20201231_1M_stomate_history.nc: same as above, but after the addition of three high-latitude shrub PFTs. ORCHIDEE_15PFT_19920101_20201231_1D_Cfluxes.nc: Same as above, but daily resolution, and only carbon flux variables (GPP, respiration, NEE, ...) for ORCHIDEE with 15 PFTs without shrubs. ORCHIDEE_18PFT_19920101_20201231_1D_Cfluxes.nc: Same as above, but for ORCHIDEE with 18 PFTs, including three new high-latitude shrub PFTs. ORCHIDEE_18PFT_PFTmap_2010.nc: map prescribing the fractional cover of all 18 ORCHIDEE PFTs, including the three new shrub PFTs.
