This repository includes the HadCM3L model priors used in the Phanerozoic data assimilation, PhanDA (Judd et al., submitted). The model simulations were carried out by the Bristol Research Initiative for the Dynamic Global Environment (BRIDGE) group using the computational facilities of the Advanced Computing Research Centre at the University of Bristol (Bristol, UK).
\n\nIncluded in this repository is 1 excel file containing the details of each simulation ("ExperimentInfo.xlsx") and 32 sets of zipped files, each containing 545 netCDFs. The naming convention of these files is as follows:
\n\nExperimentName_ExperimentNumber_ExperimentAge_CO2_ExperimentMean_VariableName.nc
\n\nThere are 8 sets, or "suites" of model simulations, indicated by the ExperimentName. They all begin with "scotese," referencing that they use the paleogeographic reconstructions of Scotese (2016). The different suites were run assuming different CO2 values and model versions (see Judd et al, submitted and Valdes et al., 2021 for further details):

*PUMA refers to the "Providing Unified Model Access" service. Here, we have provided the database names of the youngest (0 Ma) and oldest (541 Ma) simulations, respectively.
\n\nNote that the scotese_spinupa and scotese_02 suites were originally published in Valdes et al., 2021.
\n\nThe ExperimentNumber, ExperimentAge, and CO2 values are linked to each specific model simulation. In total, each of the 8 suites was run at a total of 109 time slices, for a total of 872 discrete model simulations (8 x 109). Details can be found in the ExpInfo excel file included in the repository.
\n\nAs outlined in Judd et al. (submitted), each model simulation was spun up for at least 3,000 yrs. To boost natural variability in the model prior, the last 100 yrs of each simulation was subdivided into 5 x 20-yr averages, as indicated by the ExperimentMean label. This results in 4,360 unique model priors (8 x 109 x 5).
\n\nWe have included four variables: tas (2m air temperature), tos (sea surface temperature), so (sea surface salinity), and pr (precipitation). Each variable has its own file, for a total of 17,440 netCDFs (8 x 109 x 5 x 4).
