[{"title":"Marine-Atmospheric Emitted Radiance Interferometer from the high-Arctic ASCOS expedition 2008","summary":"During the ASCOS expedition the temperatures of the cloud-base, ambient air, and surface were very accurately measured using the Marine-Atmospheric Emitted Radiance Interferometer (MAERI) instrument, which also measures downwelling longwave radiation at a very high spectral resolution. The instrument was located at the port bridge-roof wing on the 7th deck of the Icebreaker Oden.","citations":"Tjernstr\u00f6m, M. et al. 2014.

DOI:10.5194\/acp-14-2823-2014","comments":"The Marine-Atmospheric Emitted Radiance Interferometer (MAERI) instrument measures downwelling longwave radiation at a very high spectral resolution and was located at the port bridge-roof wing on the 7th deck. The isntruments alternates sensing radiation at a 45\u00b0 upward angle, horizontally straight out from the ship, at a 45\u00b0 downward angle and into a chilled calibration cavity. In addition to the high-resolution frequency spectra from the upward scans, all scans provide information that can be converted to a radiative temperature. Hence, it measures very accurately both cloud-base, ambient air, and surface temperatures.Original address: http:\/\/www.ascos.se\/index.php?q=node\/291\n\n\nFiles:\nOden_ASCOS2008_MAERI.txt (517.58 KB)\n080802C1.nc (604.25 KB)\n080802C2.nc (568.72 KB)\n080803C1.nc (1.22 MB)\n080803C2.nc (1.15 MB)\n080804C1.nc (893.87 KB)\n080804C2.nc (844.52 KB)\n080805C1.nc (1.34 MB)\n080805C2.nc (1.27 MB)\n080806C1.nc (1.07 MB)\n080806C2.nc (1.01 MB)\n080807C1.nc (1.4 MB)\n080807C2.nc (1.32 MB)\n080808C1.nc (1.44 MB)\n080808C2.nc (1.36 MB)\n080809C1.nc (1.22 MB)\n080809C2.nc (1.15 MB)\n080810C1.nc (947.5 KB)\n080810C2.nc (895.59 KB)\n080811C1.nc (786.6 KB)\n080811C2.nc (742.37 KB)\n080812C1.nc (1022.59 KB)\n080812C2.nc (967.1 KB)\n080813C1.nc (1.43 MB)\n080813C2.nc (1.35 MB)\n080814C1.nc (1.44 MB)\n080814C2.nc (1.35 MB)\n080815C1.nc (1.44 MB)\n080815C2.nc (1.36 MB)\n080816C1.nc (1.43 MB)\n080816C2.nc (1.35 MB)\n080817C1.nc (1.44 MB)\n080817C2.nc (1.36 MB)\n080818C1.nc (1.44 MB)\n080818C2.nc (1.36 MB)\n080819C1.nc (1.43 MB)\n080819C2.nc (1.35 MB)\n080820C1.nc (1.44 MB)\n080820C2.nc (1.36 MB)\n080821C1.nc (1.41 MB)\n080821C2.nc (1.33 MB)\n080822C1.nc (1.4 MB)\n080822C2.nc (1.32 MB)\n080823C1.nc (1.42 MB)\n080823C2.nc (1.34 MB)\n080824C1.nc (1.44 MB)\n080824C2.nc (1.36 MB)\n080825C1.nc (1.44 MB)\n080825C2.nc (1.36 MB)\n080826C1.nc (1.44 MB)\n080826C2.nc (1.36 MB)\n080827C1.nc (1.44 MB)\n080827C2.nc (1.36 MB)\n080828C1.nc (1.44 MB)\n080828C2.nc (1.36 MB)\n080829C1.nc (1.44 MB)\n080829C2.nc (1.36 MB)\n080830C1.nc (1.44 MB)\n080830C2.nc (1.36 MB)\n080831C1.nc (1.41 MB)\n080831C2.nc (1.33 MB)\n080901C1.nc (1.37 MB)\n080901C2.nc (1.29 MB)\n080902C1.nc (1.19 MB)\n080902C2.nc (1.12 MB)\n080903C1.nc (625.7 KB)\n080903C2.nc (589.15 KB)\n080904C1.nc (625.7 KB)\n080904C2.nc (589.15 KB)\n080905C1.nc (786.6 KB)\n080905C2.nc (742.37 KB)\n\n","category":"Atmosphere","subcategory":"Observations","keywords":"ASCOS; Meteorology; High Arctic; Arctic boundary layer; Arctic clouds; Longwave radiation spectra; Temperature","scientist":"Erica Key","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 for Climate Research, Stockholm University","version":"1.0","constrains":"None","access":"Free"}]
