The Steering Committee of Measurement-Model Fusion for Global Total Atmospheric Deposition is responsible for developing and implementing an action plan to guide the MMF-GTAD initiative in line with its short- and medium-term objectives. It supports the generation and dissemination of high-quality global maps and high-resolution data products on atmospheric deposition, including validated measurement datasets and model outputs. The committee also promotes the development of customized procedures, provides technical guidance, and delivers tailored products to address specific user and stakeholder needs, such as ecosystem-focused deposition assessments.
