The Integrated Global Greenhouse Gas Information System (IG3IS) - Transcom workshop and IG3IS science team Meeting was held in Paris, France from 15-18 October 2019.
The Integrated Global Greenhouse Gas Information System (IG3IS), spearheaded by the World Meteorological Organization’s Global Atmosphere Watch programme, is moving towards a broader implementation, following the approval of its Science Implementation Plan by the WMO Executive Council in June 2018, and building on the outcomes of its first Symposium and User Summit in November 2018. IG3IS combines atmospheric GHG concentration measurements with human-activity data in a modelling and analysis framework to help decision-makers take better-informed action to reduce emissions of greenhouse gases and pollutants that reduce air quality. It also strives to establish common methods and protocols to ensure the consistency on the products and services delivered at different temporal and spatial scales.
The IG3IS science implementation plan included the Inverse Modelling Crosscut Activity in support of the development and use of inverse modelling for emission estimates and to ensure that these estimates are reliable and consistent representations of what is observed in the atmosphere. Such consistency was be established through the series of the benchmarking exercise following the recommendations of the first workshop in Lund, Sweden.
The second WMO IG3IS-TRANSCOM Inverse Modelling Workshop was organized in Paris, France at Cité Internationale Universitaire de Paris from 15-16 October 2019.
The objectives of the meeting included the finalization of the definition and began the implementation of benchmarking experiments.
This workshop was followed up by the meeting of the IG3IS Science Team on 17-18 October (including half-day for Executive Session).
