High frequency measurements from Commonwealth Glacier Meteorological Station (COHM) in Taylor Valley, Antarctica from 1993 to present

Summary

Abstract: 

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

Date Range: 

November 22, 1993 to November 27, 2018
