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.

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

dataset
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.
