Final version of the project Data Viewer

EERIE has produced a multi-decadal ensemble of global Earth-system simulations that resolve ocean eddies. The models run at about 10 km in the ocean and 9–20 km horizontal resolution in the atmosphere, and together they amount to petabytes of output. These simulations reveal processes that standard climate models cannot capture, from mesoscale air–sea interaction to the representation of regional extremes. Yet the same scale and complexity that make them valuable also put them out of reach for most potential users. Working with the raw output requires high-performance computing access, familiarity with native model grids and formats, and substantial expertise in data processing. For most of the scientific community, and for practically all stakeholders, policymakers and the public, the data has so far been effectively inaccessible. The EERIE Data Viewer closes this gap. It turns the simulations into an open, interactive resource that runs in any web browser, with no downloads, accounts or computing resources needed. Raw output is processed into analysis-ready products: climatologies, anomalies, trends and regional time series on a common 0.25° grid.
