Earth2Studio

Experience the next generation of weather and climate modeling

Access a leading collection of weather and climate AI models, production-ready data sources, composable inference APIs, and GPU-accelerated workflows in one Python package.

Get Started

UV pip

$uv pip install "earth2studio[fcn]"

from earth2studio import run; from earth2studio.data import GFS
from earth2studio.io import ZarrBackend; from earth2studio.models.px import FCN
model = FCN.load_model(FCN.load_default_package())
run.deterministic(["2024-01-01"], 10, model, GFS(), ZarrBackend("fcn.zarr"))

Open platform

AI weather and climate solutions for every sector

Earth2Studio gives research groups, agencies, enterprises, developers, and classrooms a shared Python surface for models, data, verification, and operational workflows.

Scientists & researchers

Benchmark models on identical data through one API, design ensemble experiments, and verify outputs with built-in deterministic and probabilistic metrics.

Met services & agencies

Run, fine-tune, and deploy forecasting capability on infrastructure you control, from medium-range global guidance to rapid regional workflows.

Enterprise

Build ensemble risk workflows for energy, insurance, logistics, agriculture, and climate resilience with reproducible AI forecasts.

Developers

Build weather-aware APIs, dashboards, agents, and decision products on a composable SDK that keeps models, data, IO, and workflows separate.

Educators & students

Teach Earth system AI with an open on-ramp that can fetch data, load models, run forecasts, and store outputs using familiar scientific Python tools.

Open Source Integrated

Agent ready

Automate setup discovery and first forecasts

Install Earth2Studio skills, then ask your coding agent to recommend a model, configure an environment, fetch data, or launch a deterministic forecast.

Run a forecast, then make it your own

Earth2Studio keeps the pieces separate: data sources fetch initial states and observations, models transform state, IO stores results, and workflows compose them. Easy to get started, easy to extend.
