Global Downscaled Projections for Climate Impacts Research

The World Climate Research Programme's 6th Coupled Model Intercomparison Project (CMIP6) represents an enormous advance in the quality, detail, and scope of climate modeling.

The Global Downscaled Projections for Climate Impacts Research dataset makes this modeling more applicable to understanding the impacts of changes in the climate on humans and society with two key developments: trend-preserving bias correction and downscaling. In this dataset, the Climate Impact Lab provides global, daily minimum and maximum air temperature at the surface (tasmin and tasmax) and daily cumulative surface precipitation (pr) corresponding to the CMIP6 historical, ssp1-2.6, ssp2-4.5, ssp3-7.0, and ssp5-8.5 scenarios for 25 global climate models on a 1/4-degree regular global grid.

Accessing the data

GDPCIR data can be accessed on the Microsoft Planetary Computer: planetarycomputer.microsoft.com/dataset/group/cil-gdpcir

The dataset is made of collections distinguished by data license at the time of publication:

Each modeling center with bias corrected and downscaled data in this collection falls into one of these license categories - see the table below to see which model is in each collection, and see the section below on Citing, Licensing, and using data produced by this project for citations and additional information about each license. For examples of how to browse the collections and load the data using python, see the example use section below.

Data format & contents

The data is stored as partitioned zarr stores (see https://zarr.readthedocs.io), each of which includes thousands of data and metadata files covering the full time span of the experiment. Historical zarr stores contain just over 50 GB, while SSP zarr stores contain nearly 70GB. Each store is stored as a 32-bit float, with dimensions time (daily datetime), lat (float latitude), and lon (float longitude). The data is chunked at each interval of 365 days and 90 degree interval of latitude and longitude. Therefore, each chunk is (365, 360, 360), with each chunk occupying approximately 180MB in memory.

Historical data is daily, excluding leap days, from Jan 1, 1950 to Dec 31, 2014; SSP data is daily, excluding leap days, from Jan 1, 2015 to either Dec 31, 2099 or Dec 31, 2100, depending on data availability in the source GCM.

The spatial domain covers all 0.25-degree grid cells, indexed by the grid center, with grid edges on the quarter-degree, using a -180 to 180 longitude convention. Thus, the “lon” coordinate extends from -179.875 to 179.875, and the “lat” coordinate extends from -89.875 to 89.875, with intermediate values at each 0.25-degree increment between (e.g. -179.875, -179.625, -179.375, etc).

Notes:

[*]At the time of running, no ssp1-2.6 precipitation data was available for the FGOALS-g3 model. Therefore, we provide tasmin and tamax for this model and experiment, but not pr. All other model/experiment combinations in the above table include all three variables.
[†]The institution which ran MPI-ESM1-2-HR’s historical (CMIP) simulations is MPI-M, while the future (ScenarioMIP) simulations were run by DKRZ. Therefore, the institution component of MPI-ESM1-2-HR filepaths differ between historical and SSP scenarios.

Project methods

This project makes use of statistical bias correction and downscaling algorithms, which are specifically designed to accurately represent changes in the extremes. For this reason, we selected Quantile Delta Mapping (QDM), following the method introduced by Cannon et al. (2015), which preserves quantile-specific trends from the GCM while fitting the full distribution for a given day-of-year to a reference dataset (ERA5).

We then introduce a similar method tailored to increase spatial resolution while preserving extreme behavior, Quantile-Preserving Localized-Analog Downscaling (QPLAD).

Together, these methods provide a robust means to handle both the central and tail behavior seen in climate model output, while aligning the full distribution to a state-of-the-art reanalysis dataset and providing the spatial granularity needed to study surface impacts.

A publication providing additional detail is in review for publication in Geoscientific Model Development and a pre-print can be accessed in EGUsphere: https://egusphere.copernicus.org/preprints/2023/egusphere-2022-1513/.

The downscaleCMIP6 Repository

The ClimateImpactLab/downscaleCMIP6 repository contains infrastructure setup, argo workflows, and validation notebooks which together produce the bias corrected and downscaled daily 1/4-degree CMIP6 tasmin, tasmax, and pr data for the Climate Impact Lab Global Downscaled Projections for Climate Impacts Research (CIL GDPCIR) project.

Acknowledgements

This work is the result of many years worth of work by members of the Climate Impact Lab, but would not have been possible without many contributions from across the wider scientific and computing communities.

Specifically, we would like to acknowledge the World Climate Research Programme's Working Group on Coupled Modeling, which is responsible for CMIP, and we would like to thank the climate modeling groups for producing and making their model output available. We would particularly like to thank the modeling institutions whose results are included as an input to this repository (listed above) for their contributions to the CMIP6 project and for responding to and granting our requests for license waivers.

We would also like to thank Lamont-Doherty Earth Observatory, the Pangeo Consortium (and especially the ESGF Cloud Data Working Group) and Google Cloud and the Google Public Datasets program for making the CMIP6 Google Cloud collection possible. In particular we're extremely grateful to Ryan Abernathey, Naomi Henderson, Charles Blackmon-Luca, Aparna Radhakrishnan, Julius Busecke, and Charles Stern for the huge amount of work they've done to translate the ESGF CMIP6 netCDF archives into consistently-formattted, analysis-ready zarr stores on Google Cloud.

We're also grateful to the xclim developers (DOI: 10.5281/zenodo.2795043), in particular Pascal Bourgault, David Huard, and Travis Logan, for implementing the QDM bias correction method in the xclim python package, supporting our QPLAD implementation into the package, and ongoing support in integrating dask into downscaling workflows. For method advice and useful conversations, we would like to thank Keith Dixon, Dennis Adams-Smith, and Joe Hamman.
