Upper Howard Meteorological Station Daily Averages (2001-2004)

Summary

Abstract: 

As part of the Long Term Ecological Research in the McMurdo Dry Valleys of Antarctica, meteorological data was collected from various locations throughout Beacon, Taylor, Wright and Victoria Valleys. These files contain data for the Upper Howard Glacier meteorology station daily averages, as derived from the 15-min high-frequency data. The Upper Howard Glacier meteorological station was added to the McMurdo Dry Valley network in the 2001-2002 field season in Taylor Valley and removed November 8, 2004.

Methodology

Methods: 

The Upper Howard Glacier meteorological station was added to the McMurdo Dry Valley network in the 2001-2002 field season in Taylor Valley and removed November 8, 2004.
 
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: 

The Upper Howard Meteorological Station was removed on November 8, 2004. (Moved to Blood Falls) 

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 found at the following address:
