Table 3.

Pearson correlation coefficients of multiple linear regressions of half-hourly methanol emission and deposition fluxes as a function of several independent variables (PAR – photo-synthetic photon flux density, RH – relative air humidity TA – air temperature, SWC soil water content, u_*, – friction velocity ET – evapotranspiration, GPP – gross primary productivity, TSEOP – time since end of precipitation, n – number of measurements).
