Query: Reconciling high resolution climate datasets using KrigR   There is an increasing need for high spatial and temporal resolution climate
data for the wide community of researchers interested in climate change and its
consequences. Currently, there is a large mismatch between the spatial
resolutions of global climate model and reanalysis datasets (at best around
0.25o and 0.1o respectively) and the resolutions needed by many end-users of
these datasets, which are typically on the scale of 30 arcseconds (~900m). This
need for improved spatial resolution in climate datasets has motivated several
groups to statistically downscale various combinations of observational or
reanalysis datasets. However, the variety of downscaling methods and inputs
used makes it difficult to reconcile the resultant differences between these
high-resolution datasets. Here we make use of the KrigR R-package to
statistically downscale the world-leading ERA5(-Land) reanalysis data using
kriging. We show that kriging can accurately recover spatial heterogeneity of
climate data given strong relationships with co-variates; that by preserving
the uncertainty associated with the statistical downscaling, one can
investigate and account for confidence in high-resolution climate data; and
that the statistical uncertainty provided by KrigR can explain much of the
difference between widely used high resolution climate datasets (CHELSA,
TerraClimate, and WorldClim2) depending on variable, timescale, and region.
This demonstrates the advantages of using KrigR to generate customized high
spatial and/or temporal resolution climate data.
