The Global Terrestrial ObservingSystem (GTOS)
The Global Terrestrial Observing System (GTOS) is a programme for observations, modelling, and analysis of terrestrial ecosystems to support sustainable development. GTOS facilitates access to information on terrestrial ecosystems so that researchers and policy makers can detect and manage global and regional environmental change. The GTOS programme structure is composed of panels, regional projects and technical programmes. Implementation of the observing programs is accomplished using satellite missions, technical programs, and existing and expanded terrestrial networks.

Access data and Information by Essential Climate Variable (ECV)
Access data and Information by Programme Activity
- SITE DATA - The Terrestrial Ecosystem Monitoring Sites (TEMS) is an international directory of sites (named T.Sites) and networks that carry out long-term terrestrial monitoring and research activities. THE TEMS DATABASE IS OFFLINE UNTIL FURTHER NOTICE
- NETWORKS - The Global Terrestrial Observing Network (GT-NET) is a system of thematic observation networks. Each represents an organized effort for a particular theme, habitat type or region. The global networks are: River Discharge (GTN-R)**, Glacier (GTN-G)**, Hydrology (GTN-H)**, Lake Level/Area (GTN-L)**, Mountains Network and Permafrost (GTN-P)**
- BIODIVERSITY - GTOS Biodiversity Initiative (B-GTOS)
** Joint programs with GCOS (See the GCOS/GTOS Joint Programs Matrix)
Access Data and Information by Technical Panel
- COASTAL - The Coastal-GTOS (C-GTOS) is a program GTOS has developed in collaboration with other coastal programmes and international initiatives to focus on
global and regional change in coastal areas.
There is a clear need for information on global and regional change in coastal areas. Collection of in situ and remote sensing data must be improved and associated data management, model production and communication infrastructure developed to provide free and timely information to developed and developing nations.
- LAND-COVER - The Global Observation of Forest and Land Cover Dynamics (GOFC-GOLD) panel for climate is a coordinated international effort to supply space-based and in situ forest and land cover observations to obtain an accurate, reliable and quantitative understanding of global change processes.
- TERRESTRIAL CARBON - The Terrestrial Carbon Observation (TCO) Panel of GTOS supports the coordination of a global carbon observation system and its database.
- CLIMATE - Terrestrial Observing Panel for Climate (TOPC) was jointly established by GTOS and GCOS. TOPC is a group of scientists with expertise in climate change issues and focuses on the identification of terrestrial observation requirements.
Access data and Information by Joint Observing Program
- The GCOS requirements for land surface climate observations have been developed jointly with those of the GTOS by the Terrestrial Observation Panel for Climate (TOPC).
