The stepped rotating cylinder electrode (SRCE) geometry has been developed as a simple aid to the practical study of the flow-enhanced corrosion and applied electrochemistry problems commonly observed under conditions of disturbed, turbulent flow. The electrodeposition of cupric ions from an acid sulphate plating bath has been used to characterise differential rates of mass transfer to the SRCE. The variation in thickness of electrodeposited copperfilms has allowed the mapping of local rates of mass transfer over the active surface of this geometry. Both optical and scanning electron microscopy were used for the examination of metallographic sections to provide a high resolution evaluation of the distribution of mass transfer coefficient. Results are also discussed using the convective-diffusion model in combination with the existing direct numerical flow simulation (DNS) data for this geometry.

These are data of eddy covariance flux measurements of formic acid (HCOOH), performed by a chemical ionization mass spectrometer (CIMS) over a boreal forest canopy in Hyytiälä, Finland, in spring/summer 2014. Results from the 1-D chemical transport model runs using SOSAA (Simulate Organic vapours, Sulphuric Acid and Aerosols) are included as well. The data accompany a submission of a manuscript to Geophysical Research Letters for consideration for publication (Schobesberger et al.).
