High frequency measurements from Lake Brownworth Meteorological Station (BRHM), McMurdo Dry Valleys, Antarctica (1994-2022, 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 15-minute data from 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 30, 1994 to December 13, 2022
