Scientific Regions¶
The following regions, used in the scientific literature, are already defined:
Giorgi Regions (from Giorgi and Franciso, 2000)
SREX Regions (Special Report on Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation (SREX) from Seneviratne et al., 2012)
AR6 Regions (Iturbide et al., 2020; ESSD)
The following imports are necessary for the examples.
In [1]: import regionmask
In [2]: import matplotlib.pyplot as plt
Giorgi Regions¶
In [3]: regionmask.defined_regions.giorgi.plot(label='abbrev');
In [4]: plt.tight_layout()
AR6 Regions¶
There are 58 AR6 regions as defined in Iturbide et al. (2020). The regions cover
the land and ocean (ar6.all
). In addition the regions are also divided into land
(ar6.land
) and ocean (ar6.ocean
) categories. The numbering is kept consistent
between the categories. Note that some regions are in the land and in the ocean
categories (e.g. the Mediterranean).
Warning
The regions have changed in the review process. Please update your scripts. The
final region definitions are available at regionmask.defined_regions.ar6
.
For completeness, the submitted region definitions (also referred to as SOD regions)
are available at regionmask.defined_regions._ar6_pre_revisions
.
