| Summary: | The data set consists of meteorology and snow temperatures acquired from June 2011 through June 2014 at Summit Station, Greenland (72 ºN, -38 ºW, 3209m). The data was collected as part of the NSF funded project “Closing the Isotope Hydrology at Summit: Measurements of Source Regions, Precipitation and Post-deposition Processes”. The purpose of the data set is to complement observations of isotopic composition of surface accumulation and vapor, ultrasonic wind measurements, and hydrometeor microphysics. The data set includes the following: Air temperature at 10m: 15 June 2011 - 30 June 2014, > 97% uptime Air temperature at 2m: 15 June 2011 - 30 June 2014, > 99% uptime Relative humidity at 10m: 15 June 2011 - 30 June 2014, > 97% uptime Relative humidity at 2m: 15 June 2011 -30 June 2014, > 99% uptime Surface brightness temp. (8-12 μm): 15 June 2011 - 30 June 2014, > 94% uptime Snow temperatures surface to ~2 m depth: 1 July 2013 - 30 June 2014, > 99% uptime Wind velocity ~surface to 10 m: 1 July 2011 - 30 June 2014, 2, 5, 10m before spr. 2012 Surface height relative to tower: 1 July 2013 - 30 June 2014, > 76% uptime File naming convention: smtmet.qc.YYYYMMDD.HHMMSS.cdf
