Dataset for the estimation of BrC absorption

Ths data file named 'dM_dlogD_rBC_10min.csv' contains the mass size distribution (dM/dlogDc) of refractory black carbon measured using a single-particle soot photometer (SP2) in urban Beijing during a period from 16 Feb. 2014 to 15 Mar. 2014. The dataset is recorded line by line at a time resolution of 10 min. The first line of this file is the header line. There are 204 columns for the data file with the first 5 columns indicating the date and time of each record and the following 199 columns representing the dM/dlogDc values at corresponding diameter. The dM/dlogDc values with diameter lower than 70 nm and larger than 650 nm were excluded in the analysis according to the detection limit of SP2.The data file named 'CorBC_AE31_HourAVG_AE-31.csv' stored the BC concentration measured using an AE31 aethalometer averaged in a time resolution of 1 hour. The record is stored line by line initial with a header line. The first 4 columns indicate the date and time of each record. The following 7 columns are the loading corrected BC concentrations at 7 wavelengths (370, 470, 520, 590, 660, 880, 950 nm), then followed by the sample flow rate (1 column) and raw BC concentrations at the 7 wavelengths recorded by the AE31 (7 columns).
