dc.description.abstractParticle size distribution data measured with a differential mobility particle sizer (DMPS) through total (tot) and interstitial (int) inlets at Puijo SMEAR IV station in Kuopio, Finland. Data for years 2006-2015. See detailed description: Data contains files for both inlets (tot and int) and three periods with different measured size ranges (Case_1, Case_2 and Case_3). Files are: * PUI_dmps_int_Case_1_data.csv * PUI_dmps_int_Case_2_data.csv * PUI_dmps_int_Case_3_data.csv * PUI_dmps_tot_Case_1_data.csv * PUI_dmps_tot_Case_2_data.csv * PUI_dmps_tot_Case_3_data.csv Files have the following columns (column_name: description; [unit]): * Year, Month, Day, Hour, Minute, Second: Sample time (UTC +2), [] * quality: Quality parameter; [] * sizerange_id: Size range ID (diamaters in PUI_dmps_sizeranges); [] * ntot: Total particle concentration ; [#/cm3] * ch01: Particle concentration dN/dlogDp Ch01; [#/cm3] * ch02: Particle concentration dN/dlogDp Ch02; [#/cm3] * … * ch39: Particle concentration dN/dlogDp Ch39; [#/cm3] * ch40: Particle concentration dN/dlogDp Ch40; [#/cm3] Particle diameter of the channel were shown in the second row of the tables (unit nm) Size distributions have been measured using different diameter ranges at different periods: 1. from 10 to 500 nm, 30 channels, 2.6.2006 - 31.3.2007 2. from 7 to 800 nm, 40 channels, 1.4.2007 - 31.1.2012 3. from 3 to 800 nm, 40 channels, from 1.2.2012 Sample air for the instruments is drawn through two parallel sampling lines: interstitial (int) and total (tot) inlets: * interstitial inlet (int) is equipped with an impactor with a 10-µm cut-off size followed by a cyclone with a 1.0-µm cut-off size (2.5 µm before 20 November 2009) * total air inlet (total) with heated sampling lines and snow-hood to dry the cloud droplets (cut-off size 40 µm when the wind speed is below 20 m/s) This two-inlet setup enables simultaneous interstitial and total air (interstitial + cloud drop residual) measurements when the tower is covered by clouds. The size of data: ca. 100 MB. Note: Data also available and described via AVAA SmartSMEAR: * *
