Overview of datasets available in pastclim
A number of datasets are available in pastclim. It is possible to use custom datasets as long as they are properly formatted (look at the article on how to format custom datasets if you are interested). It is possible to get a list of all available datasets with:
get_available_datasets()
#> Barreto2023, Beyer2020, CHELSA_trace21k_1.0_0.5m_vsi, Example, HYDE_3.3_baseline, Krapp2021, paleoclim_1.0_10m, paleoclim_1.0_2.5m, paleoclim_1.0_5m
#> for present day reconstructions, use "WorldClim_2.1_RESm" or "CHELSA_2.4_RESm" where RES is an available resolution.
#> for future predictions, use "WorldClim_2.1_GCM_SSP_RESm" or "CHELSA_2.1_GCM_SSP_RESm", where GCM is the GCM model, SSP is the Shared Socio-economic Pathways scenario.
#> use help("WorldClim_2.1") or help("CHELSA_2.1") for a list of available optionsA more comprehensive list can be obtained with:

#> Description:
#>
#> Spatio-temporal series of monthly temperature and precipitation
#> and 17 derived bioclimatic variables covering the last 5 Ma
#> (Pliocene<e2><80><93>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 <c3><97> 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 <c3><97> 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).

#> *Present-day reconstructions* are based on the mean for the period
#> 1981-2000 and are available at at the high resolution of 0.5
#> arc-minutes (_CHELSA_2.1_0.5m_). In 'pastclim', the datasets are
#> given a date of 1990 CE (the mid-point of the period of interest).
#> There are 19 <e2><80><9c>bioclimatic<e2><80><9d> variables, as well as monthly estimates
#> for mean temperature, and precipitation. The dataset is very
#> large, as it includes estimates for the oceans as well as the land
#> masses. An alternative to downloading the very large files is to
#> use virtual rasters, which allow the data to remain on the server,
#> with only the pixels required for a given operation being
#> downloaded. Virtual rasters can be used by choosing
#> (_CHELSA_2.1_0.5m_vsi_)
#>
#> *Future projections* are based on the models in CMIP6, downscaled
#> and de-biased using the CHELSA algorithm 2.1. Monthly values of
#> mean temperature, and total precipitation, as well as 19
#> bioclimatic variables were processed for 5 global climate models
#> (GCMs), and for three Shared Socio-economic Pathways (SSPs): 126,
#> 370 and 585. Model and SSP can be chosen by changing the ending of
#> the dataset name _CHELSA_2.1_GCM_SSP_RESm_.
#>
#> Available values for GCM are: "GFDL-ESM4", "IPSL-CM6A-LR",
#> "MPI-ESM1-2-HR", "MRI-ESM2-0", and "UKESM1-0-LL". For SSP, use:
#> "ssp126", "ssp370", and "ssp585". RES is currently limited to
#> "0.5m". Example dataset names are
#> _CHELSA_2.1_GFDL-ESM4_ssp126_0.5m_ and
#> _CHELSA_2.1_UKESM1-0-LL_ssp370_0.5m_
#>
#> As for present reconstructions, an alternative to downloading the
#> very large files is to use virtual rasters. Simply append "_vis"
#> to the name of the dataset of interest
#> (_CHELSA_2.1_GFDL-ESM4_ssp126_0.5m_vsi_).
#>
#> The dataset are averages over 30 year periods (2011-2040,
#> 2041-2070, 2071-2100). In 'pastclim', the midpoints of the periods
#> (2025, 2055, 2075) are used as the time stamps. All 3 periods are
#> automatically downloaded for each combination of GCM model and
#> SSP, and are selected as usual by defining the time in functions
#> such as 'region_slice()'.

#> CHELSA-TraCE21k data provides monthly climate data for temperature
#> and precipitation at 30 arc-sec spatial resolution in 100-year
#> time steps for the last 21,000 years. Palaeo-orography at high
#> spatial resolution and at each time step is created by combining

#> Glacial Maximum (LGM) glacier databases with the interpolation of
#> a dynamic ice sheet model (ICE6G) and a coupling to mean annual
#> temperatures from CCSM3-TraCE21k. Based on the reconstructed
