This instrument measures the atmospheric aerosol light absorption coefficient (mainly caused by black carbon, BC) by sampling ambient aerosol glass fiber filter tape. The intake of the aerosol inlet can be found on top of the observatory at approx. 5-7 m above ground. The measured absorption coefficients abs(637) refer to a wavelength of 637 nm. Raw data were originally sampled in one-minute resolution. Finally, hourly averaged MAAP data are presented here. We also provide BC concentrations (ng/m³) derived from the absorption coefficients using the specific BC mass absoption coefficient of 6.6 m²/g. -8.25 -8.25 -70.65 -70.65 -8.25 -70.65 2025-01-01T00:00:00 2026-01-01T00:00:00 42.0 42.0 Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, Bremerhaven AWI https://www.awi.de/ https://doi.org/10.13039/501100003207 AWI_ANT_2 Air chemistry observatory Neumayer_SPUSO http://www.awi.de/en/infrastructure/stations/neumayer_station/observatories/air_chemistry_observatory/technical_aspects/ -70.65 -8.25 Dronning Maud Land, Antarctica 42.0 1983-01-01T00:00:00 Neumayer_based Neumayer_based NEUMAYER III https://doi.org/10.17815/jlsrf-2-152 NEUMAYER III https://doi.org/10.17815/jlsrf-2-152 Air chemistry observatory SPUSO atmospheric gas analysers http://vocab.nerc.ac.uk/collection/L05/current/382/ Chemical property sensors 26278 CC-BY-4.0 Creative Commons Attribution 4.0 International https://creativecommons.org/licenses/by/4.0/ DATE/TIME Date/Time http://en.wikipedia.org/wiki/ISO_8601 Time T http://dbpedia.org/resource/Time Jurányi Zsófia zsofia.juranyi@awi.de start Date/Time (start) DATE/TIME Date/Time http://en.wikipedia.org/wiki/ISO_8601 Time T http://dbpedia.org/resource/Time Jurányi Zsófia zsofia.juranyi@awi.de end Date/Time (end) Duration Duration h duration http://purl.obolibrary.org/obo/PATO_0001309 Time T http://dbpedia.org/resource/Time Jurányi Zsófia zsofia.juranyi@awi.de Duration [h] Aerosol absorption at 637 nm abs(637) 1/Mm Multi angle absorption spectrometer MAAP5012 Jurányi Zsófia zsofia.juranyi@awi.de abs(637) [1/Mm] Black carbon, aerosol Aerosol BC ng/m**3 black carbon https://en.wikipedia.org/wiki/Black_carbon Density http://dbpedia.org/resource/Density Multi angle absorption spectrometer MAAP5012 Jurányi Zsófia zsofia.juranyi@awi.de Aerosol BC [ng/m**3] CurationLevelC Enhanced curation https://wiki.pangaea.de/wiki/Curation_levels aerosol aerosol absorption coefficient black carbon Neumayer Station Spuso author117680 author68456 award4463 basis5304 campaign25457 campaign3394411 curlevel30 event2245980 funder32 geocode1599 geocode1600 geocode1601 geocode8128 inst32 license21 method10711 method14011 param122806 param46445 param507212 pi68456 term1080072 term21330 term2299429 term40462 term43792 term43975 term47838 term47840 term51326 term52952 term67625 term70225
