Impact model: DBEM

Sector
Fisheries (global)
Region
global

DBEM is one of the 6 global models following the ISIMIP2a protocol which form the base of simulations for the ISIMIP2a global fisheries & marine ecosystems sector outputs; for a full technical description of the ISIMIP2a Simulation Data from Fisheries & Marine Ecosystems (Fish-MIP; global) Sector, see this DOI link: http://doi.org/10.5880/PIK.2018.005

Resolution
Spatial aggregation: regular grid
Horizontal resolution: 0.5°x0.5°
Vertically resolved: Yes
Number of vertical layers: There are two layers, surface and bottom
Temporal resolution of input data: climate variables: annual
Temporal resolution of input data: co2: annual
Input data
Observed atmospheric climate data sets used: GFDL-MOM6-COBALT2 (ocean)
Emissions data sets used: Atmospheric composition (ISIMIP3a)
Other human influences data sets used: Fishing effort
Additional input data sets: The Sea Around Us CMSY data available at thesearoundus.org
Spin-up
Was a spin-up performed?: Yes
Spin-up design: Spin-up and transition period (1841-1960). Nominal spin-up (1841-1860, fishing held constant at 1861 levels) and pre-industrial transition period (1861-1960, reconstructed fishing effort). To set-up climate-forcing variables for the entire 1841-1960 period, we used the “control run” (ctrlclim) monthly output for the years 1961-1980 (inclusive) on repeat for six cycles.
