[{"name":"oden-ascos-2008-radiometer-1","title":"Radiometer data from the high-Arctic ASCOS expedition 2008","summary":"High resolution (in time and space) vertical profiles of temperature were obtained from a 60GHz scanning microwave radiometer. The radiometer measures the brightness temperature along the line-of-sight and generates a vertical profile by scanning in the vertical plane. The vertical resolution and accuracy decreases with altitude up to the measuring top at 1.2 km. It was located on the starboard bridge-roof wing of the Icebreaker Oden with a free view to starboard. The retrieval from this instrument uses the radiosonde profiles as a first guess and thus adds information on vertical and temporal variability to the radiosonde profiles.","citations":"Tjernstr\u00f6m, M. et al. 2014.

The radiometer measures the brightness temperature over an averaged window along the line-of-sight and by scanning in the vertical plane it provides this information at decreasingly high vertical resolution and accuracy with altitude up to 1.2 km. It was located on the starboard bridge-roof wing with a free view to starboard.\nThe retrieval is based on a first-guess that comes from interpolation of radiosonde profiles; hence, this instrument adds information on vertical and temporal variability to the radiosonde profiles. At higher altitudes, it converges against the interpolated soundings and variability decreases while at lower altitudes it is consistent with the soundings in an average sense.Original address: http:\/\/www.ascos.se\/index.php?q=node\/283\n\n\nFiles:\nASCOS_60Ghz_radiometer_data_v1a.ZIP (14 MB)\n\n","category":"Atmosphere","subcategory":"Temperature","keywords":"ASCOS; Meteorology; High Arctic; Arctic boundary layer; Arctic clouds; Temperature; Vertical profiles","scientist":"Ola Persson","firstname":"Michael","lastname":"Tjernstr\u00f6m","address":"Department of Meteorology; Stockholm University","postalcode":"SE-106 91","city":"Stockholm","province":"","country":"Sweden","parameters":"Earth science > Atmosphere","location":"Ocean > Arctic Ocean","progress":"Completed","language":"English","project":"Arctic Summer Cloud-Ocean Study 2008 (Ascos)","publisher":"Bolin Centre Database","version":"1","constrains":"None","access":"Free"}]
