Gfg², funded by the European Union, is an international research-related project with focus on the use of GNSS (Global Navigation Satellite Systems) for Earth Observation in a more general sense. Within the project novel GNSS applications with outstanding social importance are identified. These applications can be classified in nine Social Benefit Areas (SBA), which address the current crucial problems of mankind: disasters, health, energy, climate, water, weather, ecosystems, agriculture, biodiversity (www.earthobservations.org).

The 2nd Gfg² summer school was held July 1-3, 2013 at GFZ Potsdam. More than 40 students and 10 lectures from 16 countries participated in this major Gfg² event.

Main foci of the lectures were:

1. Basic principles of GNSS
2. GNSS radio occultation and related applications
3. Ground based GNSS meteorology and weather forecast
4. GNSS reflectometry and related applications.

Material on the summer school is available on demand (see references).
