3-Glacier Temperature Summary

**PROVISIONAL DATA--SUBJECT TO REVIEW**

Definitions:
  Annual temperatures are for hydrologic year: Oct.1 of proceeding year through Sept 30.
  Winter temperature average:
       Sept. 1 of proceeding year to May 15 for Gulkana Glacier
       Sept. 16 of proceeding year to May 15 for Wolverine Glacier
       Nov. 1 of proceeding year to April 30 for South Cascade Glacier

       May 15 to September 15 for Wolverine Glacier
       May 1 to Oct. 31 for South Cascade Glacier

Notes:
Gulkana: Temperature sensor changed at the beginning of 1999 hydrologic year; new sensor reads about 1.1°C warmer than older sensor based on 3 years overlap. Data currently uncorrected for sensor change.
Wolverine: Temperature sensor changed at the beginning of 1999 hydrologic year; new sensor reads 0.5-1.0°C warmer than older sensor. Data currently uncorrected for sensor change.
