High frequency measurements from Miers Valley Meteorological Station (MISM), McMurdo Dry Valleys, Antarctica (2012-2022, ongoing)


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 data package contains 15-minute data from the Miers Valley Meteorological Station (MISM), located in Miers Valley.

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: 

Data sources: 



 The Miers Valley meteorological station was added to the McMurdo Dry Valley network in the 2012-13 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.


Notes 2012 - Basagic.
1. Station visit on 11/28/2012 at 9:20. Datalogger date and time are correct. Input values and wind alignment looks good. 
No ultrasonic at site, but station is still programed for measurement.
2. GPS: 78.10115, 163.78778
3. Station maintenance on 11/28/2012: power off to add additional 100 amp hr battery and new style regulator. Swapped 
Omni antenna for Yagi antenna. Swapped SM at 13:45.
4. Post-processing: Processed with telemetry data. Delete first line of data. One line missing data from station visit 11/28/2012 at 13:30, multiple repetitive lines of data were deleted between 1/3/13 and 1/9/13, no missing data during this period.
Notes 2013 - Basagic
1. Station visit on 11/21/2013 at 12:45 by Basagic, Cronin, and Doran. Datalogger date and time are correct. Input values and wind alignment looks good. No ultrasonic at site, but station is still programed for measurement.
2. Station maintenance on 11/21/2013: Swapped up facing pyranometer (old: PY28370; new: PY28169) at 13:45. swapped down facing pyranometer (old: PY18656; new PY23250) at 13:15, and quantum (old: Q9916, new:Q30803) at 13:30. 
3. Post-processing: Processed with telemetry data. Delete last line of data in SM01. No sonic ranger, all data flagged as missing. One line of missing data on August 30, 2013 (242) at 19:30. Air pressure data looks suspect. Winter battery low was 12.2v. 
On Oct 2014, Inigo splitted the GADM tables into MISM and GADM to reflect the different locations of the data streams. These data are only about miers met station.
As of July 2023, processed PAR data is still missing from 12/2/2019 14:00 - 1/21/2022 13:45 because the calibration coefficient of the sensor for this time period was lost. The sensor will need to be sent back to the manufacturer to retrieve the calibration coefficient.
