To publish the 2a agriculture data, we had to rename some files / models in order to guarantee consistency between data, publications and protocol concerning PET equations. Specifically, we changed the abbreviations for the PET equations used. For details, please refer to sections 10.3 and 10.4 of the ISIMIP2a extended protocol ...
We are happy to announce the release of the ISIMIP2a-extended simulation protocol. This protocol is very similar to the ISIMIP3a protocol which we suggest to prioritize. However, we still encourage all impact modeling teams to consider performing simulations according to this ISIMIP2a-extended protocol – even if you have already contributed simu ...
The file-naming conventions for output file has been updated to include a tag to indicate the target climate data set for the bias correction. The standard file name now has the form:
To maintain consistency with other sectors, the "man" and "nat" scenarios for forest sectors have been renamed to "nosoc" and "varsoc" respectively.Erratum in https://www.isimip.org/protocol/protocol-changes/erratum-man-and-nat-scenarios-forest-sectors-renamed-nosoc-and-varsoc/
The file names should follow this convention for the historical validation runs:<modelname>_<obs>_<bias-correction>_<clim_scenario>_<socio-econ-scenario>_<sens-scenarios>_<variable>_<region>_<timestep>_<start-year>_<end-year>.nc4The specifier can take two forms: "wfd" (bias correc ...
The historical CO2 concentrations
are also provided in the input data archive (historical_CO2_annual.txt) and are based on time series of global
atmospheric CO2 concentrations from Meinshausen, Raper, & Wigley (2011) for 1765-2005 and Dlugokencky & Tan (2014) from 2006-2013.
<variable> identifier in the file name of your output data can also be used for information about the plant functional type (pft)
in the biomes and permafrost sectors. The pft/species naming is model-specific
and hence has to be reported in the impact-model database (see www.isimip.org/impactmodels) ...
The entire ISIMIP2a protocol has now been streamlined to only include vital information pertaining to the simulation design. For technical reasons, the sector-specific protocol information have now been placed in individual chapters.
Section 5.3: Spin-up procedure for cross-sectoral integration runsOld: "For CO2 concentrations use
time‐varying historical data (as in the spin‐up for the historical simulations)
up until 2005, and switch to the RCP CO2 concentration data in 2006."
New: "For CO2 concentrations use
time‐varying historical data (as in the spin‐up for the historic ...
The historical land-use pattern provided is based on historical trends
in the HYDE3 data set, not HYDE3.1, as eronneously stated in the
protocol. The correct data set should be referenced when referring to
the land-use patterns in papers. Change in section 4.1.3, 4.2.3 and in
sector-specific tables ...
