Workshop on Measurement-Model Fusion for Global Total Atmospheric Deposition

Thematic illustration

28 February to 2 March, 2017

WMO Headquarters, Geneva, Switzerland

 

Workshop Objective

Workshop participants gathered to review the state-of-the-science and establish a GAW project on Measurement-Model Fusion for Global Total Atmospheric Deposition for the purpose of generating global maps of total atmospheric deposition and ambient gases and aerosol. 

 

Workshop Report

A draft report will be posted in May 2017.
