Abstract

A group comprising 54 countries, the European Union, and 33 international organizations is working to form the Global Earth Observation System of Systems (GEOSS) .

The GEOSS will integrate data from satellites and a variety of in situ monitors to compile comprehensive measurements of what is going on on Earth.
