Daily measurement summaries from Lake Vida Meteorological Station (VIAM), McMurdo Dry Valleys, Antarctica (1995-2022, ongoing)

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 daily measurement summaries derived from 15-minute data generated by the Lake Vida Meteorological Station (VIAM), located in Victoria Valley.

Methods: 


The Lake Vida meteorological station was added to the McMurdo Dry Valley network in the 1995-1996 field season. It was established on the shore of Lake Vida in Victoria Valley, one of the largest lakes in the dry valleys, recently discovered to have a 19 m ice cover over a hypersaline brine of undetermined depth. The station was set up to sample sensors every 30 seconds and send summary statistics (for example, averages and maximums) to solid-state storage modules every 15 minutes. This has resulted in approximately 20 values being recorded for final storage in every output interval.

Maintenance: 

July 2023: The RH sensor at this station was upgraded in January 2022. However, the measurements recorded by this new sensor are suspect. Consequently, no RH data have been released after 1/19/2022 10:45 while this issue is being investigated further.

Additional information: 

Meteorological data is collected year-round at each of the stations in the McMurdo Dry Valleys of Antarctica. After retrieving this data (usually every January), the parameters that are recorded are processed from level 0 (raw) to level 1 (processed, provided on the web). The raw data file descriptions and task lists summarize what was done to get from level 0 to level 1 for all station found at the following address: https://mcm.lternet.edu/meteorological-task-lists
