 Summary of World Weather Records (WWR) data
 -------------------------------------------

 Prior to 1951, each decade was published as a single volume with the
 first including all data through 1920.  The NCAR library has all these
 volumes and DSS has the data on tape as part of ds570.0.

 From 1951 on the WWR have been published for each decade in 6-volume
 sets,

		 Volume 1 - North America
		 Volume 2 - Europe
		 Volume 3 - West Indies, South and Central America
		 Volume 4 - Asia
		 Volume 5 - Africa
		 Volume 6 - Islands of the World
