TL;DR: In this paper, the authors explore the primary driver of variations of precipitation isotopes at multiple temporal scales (event, seasonal and inter-annual scales) using a new 1-year record of the isotopic composition of event-based precipitation and continuous near-surface water vapor at Nagoya in central Japan, and identify the key atmospheric processes controlling the storm-to-storm isotopic variations through an analysis of air mass sources and rainout history during the transport of moisture to the site, and then apply the identified processes to explain the interannual isotopic variability related to the

TL;DR: In this paper, the mixing state and temporal variation of number concentrations of the particles containing lead (Pb) and vanadium (V) were studied by using a laser ionization singleparticle aerosol mass spectrometer (LISPA-MS).

TL;DR: A highly sensitive detection system for measuring atmospheric NO(2) by means of a laser-induced fluorescence (LIF) technique at 473 nm using a diode-pumped Nd:YAG laser is reported on.

TL;DR: In this paper, a single-particle time-of-flight mass spectrometer was used to analyze the sulfate and nitrate uptake on Asian dust particles during transport from the Asian continent to the Pacific Ocean.

TL;DR: In this paper, the translational energy and the speed-resolved spatial angular distributions are derived from the Doppler profiles, from which photodissociation dynamics at each wavelength is discussed.
