GTOS missionGTOS mission
Facilitate access to information on terrestrial ecosystems.
Activities that seek to detect, understand and manage change.
Products of known accuracy to researchers and policy makers.
Work with countries to develop global, continental, regional products.
GTOS programmeGTOS programme
Produce validated data and information products with known accuracies
Stimulate advances in the assembly, use, management and exchange of large terrestrial datasets
Promote common data processing standards and interpretation methods
Support systems that provide both research and operational information on a regular and sustained basis
Strengthen links between satellite and in situ data; in particular the international conventions
Identify gaps and overlaps in current and planned earth observation programs; find ways to resolve them
Characteristics of activities
GTOS programmeGTOS programme
Areas of concentration Terrestrial climate observations (TOPC) Terrestrial carbon observations (TCOP) Forest and land cover dynamics (GOFC-GOLD) Terrestrial ecosystem monitoring sites (TEMS) Terrestrial – coastal observations (C-GTOS)
Terrestrial carbon observationsTerrestrial carbon observations
Principles Hierarchy of spatial scales
Dual-constraint approach
Predictions are compared to
estimates made from observations
Estimate regional fluxes and
uncertainties

How is the global climate system changing?
What are the primary factors forcing the climate
system?
Terrestrial climate observationsTerrestrial climate observations
TOPC science questions
Technical trainingTechnical training
Defining terrestrial observations and methods to: Characterize current climate Determine rate and causes of change Forcing and feedbacks from changing GHG concentrations
Predictive, use in assimilation models: What to observe, when, where and at what accuracy Generating products to understand and predict climate

Terrestrial carbon observationsTerrestrial carbon observations
An IGOS initiative with the following objectives 2005: estimate annual net land-atmosphere fluxes
at a sub-continental scale with a 30% accuracy globally and spatial resolution (106 km2 regionally)
2008: improve accuracy (20%) and spatial resolution (106 km2 globally)
Produce sink/source maps with the highest spatial resolution enabled by the available satellite-derived and other input products (~ 1 km2 or less)
