The formation of EANET arose primarily in response to Japanese pressure to establish effective information gathering on the looming issue of Acid Rain effects. Japan has a particular interest in rain health, as it is an important element of their national culture. Four international meetings of experts between 1993 and 1997 led to the proposal of a network for the East Asian region to address the lack of critical information on acid rain in countries of the area. Between 1998 and 2000 the network was designed, and by 2001 it had developed into the Acid Deposition Monitoring Network in East Asia (Acid Deposition and Oxidant Research Center, EANET). By 2009, the membership has grown to fourteen countries.
