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 historica..
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
