|The Dobson Ad-Hoc Committee (DAHC) is a group of experts who are involved in maintenance of the Dobson part of the global total ozone monitoring network. DAHC has been formed at the meeting of Dobson operators during the Quadrennial Ozone Symposium in L´Aquila in 1996. In 1998 the DAHC has been recognized by WMO as a body providing assistance to the Scientific Advisory Group for Ozone (SAG-Ozone) of the GAW program. Members of the DAHC are volunteers who take responsibility for particular tasks related to the maintenance of the Dobson network and closely cooperate with other specialists from the Dobson community.
