Record #214156:

Increasing influence of easterly air masses on NMHC concentrations at the Pallas-Sodankylä GAW station / Heidi Hellén, and 3 others.

Title: Increasing influence of easterly air masses on NMHC concentrations at the Pallas-Sodankylä GAW station / Heidi Hellén, and 3 others.
Author(s): Hellén, Heidi.
Date: 2015.
In: Boreal Environment Research. (2015.), Vol. 20(4) (2015)
Abstract: Analyses short-term variability of non-methane hydrocarbon (NMHC) concentrations measured between 2010-12 at Pallas, northern Finland, in addition to trends in NMHCs as measured over twenty years (1994-2013). NMHCs at Pallas show typical seasonal variation, with highest mixing ratios in winter and lowest in summer. Alkanes showed no diurnal variation, but ethene reached maximum at midday or during afternoon in summer.
