Garwood Valley Meteorological Station Measurements, 2010-2011

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 Garwood Valley meteorology station. This station reported data for about a year, during 2011. On January 11, 2012 the station was disconnected and relocated to the Miers Valley. Met data for Garwood can be obtained visiting the Garwood Ice Cliff Met Station.

Methodology

Methods: 

 The Garwood Valley meteorological station was added to the McMurdo Dry Valley network in the 2010-2011 field season. 
       
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.
 
After a season, it was decided to move this station (codename GADM) to the nearby Miers Valley (codename MISM).  The meteorology at this valley is well covered by the Garwood Valley Ice Cliff station served first by Joe Levy's group.

Maintenance: 

 
     On Season 2010/11, by Thomas Nylen
1. Converted station to LTER format
2. CR10X time was set to UTC, but changed to local daylight saving time. CR10X 55 secs behind. Changed at 12/23/2010 0930. Changed output results to local time (UTC + 13hrs)
3. Wind Pointing north, declination at site is 152 degrees
4. GPS location: 77.74738, 161.51634
5. Sensor Heights: Temp/RH = 2.5m, Wind = 3.6m and NetRad = 2.05m
6. Loaded new program Friis1011v1 on 12/23/2010 1007.
7. Processed data back to 2005. Duplicated line of data on 1/18/2008 10:55 (local time). Deleted second extra line.
8. Replaced HMP45C RH sensor on Dec 16, 2008 @ 1304 (local). Wind direction alignment checked and is pointing north.
9. Pressure added by Wisconsin AWS group on 02/04/2008 11:00
      

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:
