World Meteorological Organization

Core activities:
● Develop an Implementation Plan to establish and execute the MMF-GTAD initiative following its stated near-term and mid-term objectives;
● Facilitate the creation and dissemination of high-quality global MMF maps and high-spatial-resolution data products of atmospheric deposition on an operational basis (including the associated quality-assured measurement data sets and model outputs);
● Facilitate the development of the customized procedures, provide technical advice and tailored products for specific user and stakeholder needs (e.g., ecosystem-specific deposition, derived indicators, long-term deposition trends);
● Develop and implement research mobilization strategy to ensure continuity of the activities.

Interface with Scientific Advisory Groups:
● Work in close cooperation with SAG-TAD, SAG-RG, SAG-Apps and SAG-Aerosols on the continuous improvement to the operational products through research innovations in deposition monitoring, modelling, data assimilation/fusion and new observation systems (e.g., satellite measurements).
Interface with Expert Teams:
- Work closely with the ET-ACDM on development of the policy and practice for the sharing of the data produced by the MMF-GTAD projects and activities;
- Work closely with ET-ACNDE on the development and documentation of the user and technical observational requirements for MMF-GTAD implementation on different scales.
Interface with GAW initiative steering committees
• Collaborate on cross-cutting topics between Air Quality, climate information systems and deposition with GAFIS and IG3IS steering committees.
Interface with WMO groups
● Collaborate with the WMO and co-sponsored programmes including relevant groups under the Technical Commission on Services on the aspects of deposition for the agrometeorological services, ecosystems and ocean research.
Interface with external users and partners:
● Promote MMF-GTAD activities to international bodies and conventions, including Convention on biodiversity and FAO, stakeholders, WMO members and sponsoring bodies;
● Continuously engage data users, stakeholders and partners to meet their evolving needs and priorities and encourage their support;
● Work with existing WMO, UN partners, and regional and national measurement programmes (e.g., networks, satellites) to encourage the expansion and improvement of deposition observations to support the goals of this initiative.
