Monthly measurement summaries from Lake Brownworth Meteorological Station (BRHM), McMurdo Dry Valleys, Antarctica (1995-2022, ongoing)

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 data package contains monthly measurement summaries derived from 15-minute data generated by the Lake Brownworth Meteorological Station (BRHM), located in Wright Valley (Latitude: -77.43344, Longitude: 162.7036, Elevation: 279 meters above sea level). BRHM was established in 1994, during the 94/95 field season.

Date Range: 

December 1, 1994 to December 31, 2022
