Welcome to the ITMS Project

Welcome to the ITMS Project

The Integrated Greenhouse Gas Monitoring System for Germany (ITMS) combines measured greenhouse gas concentrations in the atmosphere with atmospheric transport and greenhouse gas inversion models to estimate national emissions. In this way, ITMS supports the national greenhouse gas inventory, which provides an overview of Germany’s greenhouse gas emissions. ITMS provides independent information that contributes to greenhouse gas reporting and climate protection.

ITMS: Supporting Germany’s Greenhouse Gas Inventory

The national greenhouse gas inventory provides an important basis for climate protection decision-making. Within the ITMS project, an innovative and operational system is being developed that supports national inventory reporting by combining greenhouse gas observations with models of sources and sinks, as well as atmospheric transport models.

LandscapeDNDC: Reliable yield simulation as the basis for German GHG inventories

Accurate representation of crop growth is essential for precise greenhouse gas budgets within the Integrated Greenhouse Gas Monitoring System (ITMS). Only if biogeochemical models correctly capture the dynamics of crops under changing weather and climate conditions can they provide reliable a-priori fluxes for atmospheric data assimilation.

New inversion method with expanded potential

August 10, 2026
As part of the ITMS project, an inversion method was developed that enables both observation-based emission estimates and the optimization of concentration fields. The scientific findings have now been published. The study confirms the ITMS demonstrator results and strengthens confidence in the ITMS inversion system and its modular approach.

We launch Phase 2: Development of the ITMS 1st Generation

August 01, 2026
The Integrated Greenhouse Gas Monitoring System (ITMS) has officially entered its second phase with the developments towards a pre-operational “ITMS 1st Generation”, running from 1.8.2026 to 31.07.2030.
