| description | <p>In the recent past, an increase in computation resources led to
the development of regional climate models with increasing domains and
resolutions, spanning larger temporal periods. A good example is the World
Climate Research Program – Coordinated Regional Climate Downscaling
Experiment for the European domain (EURO-CORDEX). This set of regional
models encompasses the entire European continent for a 130-year common period
until the end of the 21st century, while having a 12 km horizontal
resolution. Such simulations are computationally demanding, while at the
same time not always showing added value. This study considers a recently
proposed metric in order to assess the added value of the EURO-CORDEX
hindcast (1989–2008) and historical (1971–2005) simulations for the maximum
and minimum temperature over the Iberian Peninsula. This approach allows an
evaluation of the higher against the driving lower resolutions relative to
the performance of the whole or partial probability density functions by
having an observational regular gridded dataset as a reference. Overall, the
gains for maximum temperature are more relevant in comparison to minimum
temperature, partially due to known problems derived from the
snow–albedo–atmosphere feedback. For more local scales, areas near the coast
reveal higher added value in comparison with the interior, which displays
limited gains and sometimes notable detrimental effects with values around
<span class="inline-formula">−</span>30 %. At the same time, the added value for temperature extremes reveals
a similar range, although with larger gains in coastal regions and in
locations from the interior for maximum temperature, contrasting with the
losses for locations in the interior of the domain for the minimum
temperature.</p> |
