About Code for Earth

Code for Earth is an innovation programme run by the European Centre for Medium-Range Weather Forecasts (ECMWF). Its aim is to drive innovation and open source developments in the Earth sciences community – supporting developments in weather, atmosphere, and climate, Copernicus and Destination Earth (DestinE). Learn more about ECMWF, Copernicus Climate Change Service (C3S), Copernicus Atmosphere Monitoring Service (CAMS) and DestinE.

Since 2018, each summer, selected developer teams work together with experienced mentors from ECMWF and partner organisations on innovative projects. These projects are related to the broad scope of activities at ECMWF, including data science, weather, climate or other earth sciences, visualisation and more.
