Documentation for the Barreto et al 2023 dataset
Description
Spatio-temporal series of monthly temperature and precipitation and 17
derived bioclimatic variables covering the last 5 Ma (Pliocene–Pleistocene),
at intervals of 1,000 years, and a spatial resolution of 1
arc-degrees (see Barreto et al., 2023 for details).
Details
PALEO-PGEM-Series is downscaled to 1 × 1 arc-degrees spatial resolution from the
outputs of the PALEO-PGEM emulator (Holden et al., 2019), which emulates
reasonable and extensively validated global estimates of monthly temperature
and precipitation for the Plio-Pleistocene every 1 kyr at a spatial
resolution of ~5 × 5 arc-degrees (Holden et al., 2016, 2019).
PALEO-PGEM-Series includes the mean and the standard deviation (i.e.,
standard error) of the emulated climate over 10 stochastic GCM emulations
to accommodate aspects of model uncertainty. This allows users to estimate
the robustness of their results in the face of the stochastic aspects of
the emulations. For more details, see Section 2.4 in Barreto et al. (2023).
Note that this is a very large dataset, with 5001 time slices. It takes
approximately 1 minute to set up each variable when creating a region_slice or
region_series. However, once the object has been created, other operations tend
to be much faster (especially if you subset the dataset to a small number
of time steps of interest).
