Monthly measurement summaries from Lake Vanda Meteorological Station (VAAM), McMurdo Dry Valleys, Antarctica (1994-2022, 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 package contains monthly measurement summaries derived from 15-minute data generated by the Lake Vanda Meteorological Station (VAAM), located in Wright Valley. VAAM was established in 1994, during the 94/95 field season.

Methods: 

During the 1994-1995 field season, the Lake Vanda meteorological station was constructed near the mouth of the Onyx River. 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 20 minutes between November 24, 1994 and December 30, 1994, every hour between December 30, 1994 and November 21, 1995, and every 15 minutes thereafter. This has resulted in approximately 20 values being recorded for final storage in every output interval.

Station was relocated after it was blown away in Sept-2003.  Onyx River temperature (thermistor) ceased then, as seen in the data record, 

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 link: https://mcm.lternet.edu/meteorological-task-lists
