Another responsibility of the Committee includes an ongoing quarterly 

 exchange of data acquired through the monitoring programs. The ex- 

 change of monitoring information was initiated with the first quarter 

 of 1981, and is an expansion of the informal quarterly information ex- 

 change program initiated between Canada and the United States in 1976. 

 Special reports dealing with aspects of monitoring and monitoring 

 results requested by the Committee are sometimes published. Any such 

 reports are reviewed annually by the Committee. Reports reviewed by 

 the Committee during 1988 are identified in Annex 3. Exchanged data 

 and reports are available for public viewing at the agencies of the 

 participating governments or from Committee members.
