Simulated modal vegetation class averaged over 2046-2065 simulated by the MC1
dynamic global vegetation model (Bachelet et al. 2001) at a 800 m x 800 m spatial
resolution using future climate projections provided through CMIP3 (http://www-pcmdi.llnl.gov/ipcc/about_ipcc.php).
Future climate drivers were generated using statistical
downscaling (simple delta method) of general circulation model projections, in
this case MIROC 3.2 medres (Hasumi and Emori 2004) under the A2 emission
scenario (Naki?enovi? et al. 2000). The deltas (differences for temperatures
and ratios for precipitation) were used to modify PRISM 800 m historical
baseline (Daly et al. 2008).
Note: The MC1 model is described in data basin (http://databasin.org/climate-center/features/mc1-dynamic-global-vegetation-model).
