Material: Coarse aerosol samples (Dp > 2.5 µm) were collected at the NOTO Ground-based Research Observatory (NOTOGRO, 37.45°N, 137.36°E), located in a remote area of the Noto Peninsula, Japan, from August 2014 to March 2016. Sampling was performed weekly using a quartz fiber filter (QR-100, ADVANTEC, Tokyo, Japan), a high-volume air sampler (AH-600F, SIBATA, Tokyo, Japan), and a PM2.5 classifier (SIBATA, Tokyo, Japan) at a flow rate of 700 L/min on the roof of the third floor. Magnetic analytical data: One of five strips of a quartz filter was cut out, and the magnetization measured using a pulse magnetizer (PM9, Magnetic Measurements, Lancashire, UK) and a SQUID magnetometer (750, 2G Enterprises, California, USA). Chemical analytical data: Sequential dissolution of aerosol samples was performed to identify aerosol sources. Some of five strips of a quartz filter were treated with 5% acetic acid (12 h) and the extraction was then defined as the HOAc-soluble fraction. On the other hand, the residue which was defined as the HOAc-insoluble fraction, was completely dissolved in a mixture of HNO3-HF-HCL. After column separation, the major and trace elements for each fraction and Pb isotopes were analyzed using ICP-MS (7500cx, Agilent Technologies, California, USA) and a double-focusing multicollector ICP-MS (NEPTUNE, Thermo Fisher Scientific, Massachusetts, USA), respectively. Pb isotopes of blank filters were analyzed only for the HOAc-insoluble fraction. *Details: Please refer to our report (
