AWS1-Meteorology

The automatic weather station AWS1 was installed in October 1990 and removed in 2018. We included the main parameters from this station in the GEM database as most parameters are continued at the GeoBasis automatic weather station (AWS2). AWS1 time stamp refer to UTC-3. The automatic weather station was installed at the scientific leader´s house approximately 25 meter above sea level and 300 m from the coast. Wind (speed and direction) and Air temperature were measured at a 9.5 meter high mast. Liquid precipitation were measured at a 2 meter high separate mast. All parameters were logged by 30 minutes interval. Data were monitored and stored by AANDERAA instruments and datalogger. Find more information about the AWS1 station on: http://img.kb.dk/tidsskriftdk/pdf/gto/gto_0095-PDF/gto_0095_72093.pdf. Due to a datalogger failure, average wind speed data was not available until 26 May 1994. The wind speed measurements ends by 31 December 2012. The relative humidity measurements ends by 16 November 2012. The station had a breakdown in July 2002 and remained unstable until October 2004. During that period, the main parameters were gap-filled with data from nearby stations. Find ground temperatures measured at AWS1 under Soil (AWS1-GroundTemperature).
