Data Catalog

Open the Data Catalog

The Data Catalog is a searchable STAC (SpatioTemporal Asset Catalog) browser listing every dataset hosted on the Cal-Adapt: Analytics Engine. It’s the best place to check what’s available before you start pulling data: models, scenarios, variables, and spatial and temporal resolution, along with metadata for each collection.

Use the Data Catalog to:

Browse available datasets by variable, scenario, model, or downscaling method
View metadata describing each collection’s spatial and temporal coverage
Get direct links to the underlying Zarr and NetCDF stores referenced by Data Access Methods

Overview

The Cal-Adapt: Analytics Engine hosts a variety of climate data with varying levels of support from our analytical tools. Many of these datasets have been converted to cloud-optimized formats, and all are publically available in our AWS S3 bucket. Below is a non-exhaustive summary of our highlighted datasets, including their source, download link, catalog link, description, and where to learn more.

Climate Model Simulations

Downscaled climate projections produced for California’s Fifth Climate Change Assessment, fully integrated into the Analytics Engine’s Data Catalog and climakitae tooling. See the Climate Model Simulations page for full details on models, downscaling methods, and scenarios.

WRF

Animated map of WRF-simulated 2m air temperature at 3km resolution over California for 2030.

Description: 8 unique models downscaled at 45 km, 9 km (WECC region), and 3 km (California) resolution. Primarily SSP3-7.0, with limited SSP2-4.5/SSP5-8.5 runs. Native hourly resolution, plus a WRF-ERA5 historical reanalysis.

LOCA2

Description: 15 unique models downscaled at 3 km resolution over California. Available for SSP2-4.5, SSP3-7.0, and SSP5-8.5. Bias-corrected for all models, at native daily resolution.

Climate Reanalysis Data

Description: ERA5 historical climate reanalysis dataset, dynamically downscaled at 45 km, 9 km (WECC region), and 3 km (California) resolution to match the WRF grid. Available at daily and hourly resolution. Provides an observationally-constrained historical reconstruction, useful for studying the historical record or specific meteorological events like heatwaves and droughts.
