Methodology

Purpose: 

Meteorological data are collected year-round at each of MCM LTER stations. Data are manually downloaded from the meteorological stations during the austral summer. Raw 15 minute data (Level 0) is processed and provided as Level 1 data on the MCM LTER website. Field notes, sensor information, processing procedures, QA/QC, and metadata is provided in the Meteorological Post Processing Documentation and Task Lists for each field season at the following address: https://mcm.lternet.edu/meteorological-task-lists 

Methods: 

The station captured data first on the 2006/07 season, installed by Cuffey and others, and brought to LTER format by Thomas Nylen during the 2010/11 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.

Maintenance: 

In 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
