This package contains monthly measurement summaries derived from 15-minute data generated by the Canada Glacier Meteorological Station (CAAM), located in Taylor Valley (Latitude: -77.61334, Longitude: 162.96437, Elevation: 264 meters above sea level). CAAM was established in 1994, during the 94/95 season. 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 1994-12-01 2022-12-31 ground condition July 2023: It was discovered that the 3m aspirated air temperature measurements from 2012-01-04 16:30 onward were actually 1m air temperature measurements. This error has been corrected, and the AIRT and AIRT3ASP data files have been updated accordingly.

The station and program both  belonged to Scott Tyler at the Desert Research Institute (DRI) so they were slightly different than the LTER standard. However, the station was set up to  monitor all of the standard meteorological parameters, as well as net radiation and sensible and latent heat fluxes with the use of the eddy correlation sensors  during the summer. Information was gathered with a sampling frequency of every 1 second and averaging &amp; output interval of every 20 minutes using this  setup from December 1, 1994 to January 21, 1995.    On November 20, 1995, Karen Lewis established a permanent meteorology station  on Canada Glacier with eddy sensors. It was set up to sample sensors regularly  and send summary statistics (for example, averages and maximums) to solid-state storage modules every:        15 minutes between November 20, 1995 and January 16, 1997,    15 minutes between January 12, 1998 and January 16, 1998,    10 minutes between January 16, 1998 and January 30, 1998,    15 minutes thereafter.       This has resulted in approximately 20 values being recorded for final storage in every output interval.    (NOTE: Between Jan 16, 1997 @ 09:30 and Jan 12, 1998 @ 21:15 the  station was taken down and brought to the U.S. It was taken back to Antarctica for the 1997-98 season andamp; set up on January 12, 1998).  On December 1, 1994, Gayle Dana established a summer-only eddy correlation station on Canada Glacier.
