abstract = "Several sets of reference regions have been used in the literature
for the regional synthesis of observed and modelled climate and
climate change information. A popular example is the series of
reference regions used in the Intergovernmental Panel on Climate
Change (IPCC) Special Report on Managing the Risks of Extreme
Events and Disasters to Advance Climate Adaptation (SREX). The
SREX regions were slightly modified for the Fifth Assessment
Report of the IPCC and used for reporting subcontinental observed
and projected changes over a reduced number (33) of
climatologically consistent regions encompassing a representative
number of grid boxes. These regions are intended to allow analysis
of atmospheric data over broad land or ocean regions and have been
used as the basis for several popular spatially aggregated
datasets, such as the Seasonal Mean Temperature and Precipitation
in IPCC Regions for CMIP5 dataset. We present an updated version
of the reference regions for the analysis of new observed and
simulated datasets (including CMIP6) which offer an opportunity
for refinement due to the higher atmospheric model resolution. As
a result, the number of land and ocean regions is increased to 46
and 15, respectively, better representing consistent regional
climate features. The paper describes the rationale for the
definition of the new regions and analyses their homogeneity. The
regions are defined as polygons and are provided as coordinates
and a shapefile together with companion R and Python notebooks to
illustrate their use in practical problems (e.g. calculating
regional averages).We also describe the generation of a new
dataset with monthly temperature and precipitation, spatially
aggregated in the new regions, currently for CMIP5 and CMIP6, to
be extended to other datasets in the future (including
observations). The use of these reference regions, dataset and
code is illustrated through a worked example using scatter plots
to offer guidance on the likely range of future climate change at
the scale of the reference regions. The regions, datasets and code
(R and Python notebooks) are freely available at the ATLAS GitHub
