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 Howard Glacier Meteorological Station (HODM), located in Taylor Valley (Latitude: -77.67121, Longitude: 163.07732, Elevation: 472 meters above sea level). HODM was established in 1993, during the 93/94 field season.
At the start of the 1993-1994 field season, the Howard Glacier meteorological station was constructed at the same coordinates as stake 31 on the glacier's mass balance grid (latitude of 77-40-17.36222 S, longitude of 163-04-44.83507 E, and elevation of 472.49343 meters above sea level). 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 20, 1993 and November 27, 1995, and every 15 minutes thereafter. This has resulted in approximately 20 values being recorded for final storage in every output interval.

Meteorological data is collected year-round at each of MCM LTER stations. Data is 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
