High frequency measurements from Howard Glacier Meteorological Station (HODM) 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 Howard Glacier Meteorological Station (HODM), located in Taylor Valley (Latitude: -77.67121, Longitude: 163.07732, Elevation: 472 meters above sea level). HODM was established in 1993, during the 93/94 field season.

Date Range: 

November 20, 1993 to November 27, 2018
