TL;DR: In this article, the vertical profiles of ultrafine and micronic particles across the planetary boundary layer and the free troposphere over a Mediterranean urban environment were investigated using a tethered balloon equipped with a miniaturized condensation particle counter.

TL;DR: In this paper, ground-level and vertical measurements of ozone (O3), other gaseous pollutants (NO, NO2, CO, SO2) and aerosols were carried out in the plains (Vic Plain) and valleys of the northern region of the Barcelona metropolitan area (BMA) in July 2015, an area typically recording the highest O3 episodes in Spain.

TL;DR: In this article, the authors evaluated the atmospheric dynamics leading to summer ozone (O 3) episodes in the Madrid air basin by means of measuring a 3-D distribution of surface O 3 concentrations.

TL;DR: The vertical profile of new particle formation (NPF) events was studied by comparing the aerosol size number distributions measured aloft and at surface level in a suburban environment in Madrid, Spain, using airborne instruments as discussed by the authors.

TL;DR: These observations record the emission of fine to ultrafine FePM by frictional wear at elevated temperatures that promote rapid partial (or complete) oxidation of the native metal.
