Commonwealth Glacier Meteorological Station Daily Averages, 1993-present

Summary

Abstract: 

As part of the McMurdo Dry Valleys Long Term Ecological Research program (MCM LTER), meteorological data is collected from various locations throughout the McMurdo Dry Valleys of Antarctica. This package contains daily averages derived from 15-minute data generated by the Commonwealth Glacier Meteorological Station (COHM), located in Taylor Valley. COHM was established in 1993, during the 93/94 field season.

Date Range: 

Monday, November 22, 1993 to Tuesday, November 27, 2018
