Therefore a Multi-Angle Absorption Photometer (MAAP) and two Particle Soot\/Absorption Photometers (PSAP) were set up in combination with a Differential Mobility Particle Sizer (DMPS) to measure light absorption on a size resolved grid.\r\n\r\nThe goal was to see in which particle sizes the most absorbing particles are present and to get a particle size distribution for ambient air and absorbing aerosols. Therefore PSAP #2 was built up behind the DMPS to get the light absorption coefficient in the according size bin. The DMPS selects a particle size range and counts the particles, after that the PSAP #2 measures the absorption of the outgoing flow. The MAAP and PSAP #1 was used as a control background measurement to know how much light the ambient air absorbs over all sizes and to compare with each other for data quality purposes.\r\n\r\nThe data were collected at Stockholm University, Stockholm, Sweden, from 2019-01-11 15:09 until 2019-02-25 07:50. All absorption coefficients were corrected according to established procedures.","url":"http:\/\/bolin.su.se\/data\/cremer-2020-size-resolved-1","keywords":["Atmosphere","Aerosols","Black carbon","Soot","MAAP","PSAP","DMPS","BC","Absorption","Absorption coefficient","Earth science > Atmosphere > Aerosols > Aerosol particle properties"],"creator":{"@type":"Person","name":"Roxana Cremer, Paul Zieger, Johan Str\u00f6m"},"citation":"Tunved P, Cremer RS, Zieger P, Str\u00f6m J (2021) Using correlations between observed equivalent black carbon and aerosol size distribution to derive size resolved BC mass concentration: a method applied on long-term observations performed at Zeppelin station, Ny-\u00c5lesund, Svalbard, Tellus B: Chemical and Physical Meteorology 73:1, 1-17.
