Concentration weighted trajectory fields quantifying the site-specific influence of source and relative sink areas to the de-seasonalised and de-trended CH4 concentrations (in ppb) at the high-alpine receptor sites Jungfraujoch (JFJ), Plateau Rosa (PRO), Sonnblick (SOB) and Schneefernerhaus (UFS), respectively, over the entire study period 2011–2015
