GT-Net Data Access
Global Terrestrial Observing Network (GT-Net) is a system of observation networks: Coastal (GTN-C), Ecology (GTN-E, Glacier (GTN-G), Hydrology (GTN-H), Mountain (GTN-M), and Permafrost (GTN-P). Each represents an organized effort for a particular theme, habitat type or region. The formation of GT-Net has been pursued by the Terrestrial Observation Panel for Climate (TOPC) on behalf of the Global Terrestrial Observing System (GTOS) and the Global Climate Observing System (GCOS). Regional networks are being developed through GTOS regional programs. |

(GTN-C)
- GTN-C is a joint project of the Global Ocean Observing System (GOOS) and the Global Terrestrial Observing System (GTOS). The GOOS Scientific and Technical Committee (GSSC) oversees the marine and estuarine ecosystems work and GTOS is responsible for the terrestrial component.

Mountains Network (GTN-M)
- GTOS GTN-M endorses three main mountain-related activities devoted primarily to monitoring and change detection:
- the Global Observation Research Initiative in Alpine Environments Project (GLORIA),
- the Mountain Research Initiative (MRI), and
- the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL)

Permafrost Network (GTN-P)
- The Global Terrestrial Network for Permafrost (GTN-P), approved in 1999 and coordinated by the International Permafrost Association (IPA), comprises two international monitoring networks: Thermal State of Permafrost (TSP) and Circumpolar Active Layer Monitoring (CALM).
