High frequency measurements from Lake Fryxell Meteorological Station (FRLM) 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 data package contains 15-minute data from the Lake Fryxell Meteorological Station (FRLM), located in Taylor Valley. BOYM was established in 1993, during the 93/94 field season.

Date Range: 

December 7, 1993 to December 6, 2018
