Dataset for brown carbon absorption estimation

Ths data file named 'dN_dlogD_rBC_10min.csv' contains the number size distribution (dN/dlogD) 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 dN/dlogD values at corresponding diameter. The dN/dlogD values with diameter lower than 70 nm and larger than 600 nm were excluded in the analysis according to the detection limit of SP2.The data file named 'MieAbs_3hMoveAVG_Base950nm_C3.5_RI1.50_all.CSV' stored the absorption coefficient with 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 measured absorption coefficient at 7 wavelengths (370, 470, 520, 590, 660, 880, 950 nm) using an aethalometer (AE31), then followed by the bare BC absorption coefficient at the 7 wavelengths and coated BC absorption coefficient at the 7 wavelengths. The last column represents the mean relative coating thickness of BC particles.<br>
