Group: Summary

   This dataset includes frost tube data from 37 stations in the Upper Midwest 
   (Minnesota, North Dakota, Wisconsin), USA. The responsible agency was the St. 
   Paul District of the U.S. Army Corps of Engineers. These data were collected 
   during 1971-1981 (no data for 1976/77) by cooperative observers who gathered 
   the data for use in their spring run-off hydrologic predictions. The observers 
   had frost tubes installed by District personnel in their back yards. The early 
   penetration of frost at the beginning of the freezing season was not observed, 
   but most observers picked up the record when 1 or 2' of frost had occurred. 
   This data base, a preliminary version, was constructed by Richard K. Haugen 
   and Glenn King from the manuscript records of the cooperative observers and is 
   presented on the CAPS Version 1.0 CD-ROM, June 1998.
