The fortnightly time series extends between August 2007 and December 2016. Throughfall was sampled on the 20 NUMEX plots with Hellmann-type collectors. On each plot 20 replicates were collected, volume-weighted and bulked to one sample per plot. Electrical conductivity and pH values were measured immediately in unfiltered aliquots in the laboratory of the ECSF.

Litterfall was collected on all 20 plots at NUMEX on 6 subplots per plot (A-F) with polyethylene mesh traps (0.6 x 0.6 m). On each plot, two of the six litterfall traps were randomly sampled monthly. The samples were dried at 40 °C for one week and stored at the ECSF until transport to Germany or Switzerland for chemical analyses. The two collected replicates were bulked per plot and collecting interval resulting in one litterfall sample per plot and month. Samples were ground to <50 µm with a planetary ball mill (Retsch PM200, Haan, Germany) prior to isotope measurements of d13C and d15N by EA/IRMS (ThermoFisher, Bremen, Germany)

Geographic coverage:	Investigation areas RBSF, Cajanuma, Bomboscaro
Abstract:	Measurements of gas flux (CO2, CH4, N2O) in canopy... Abstract: Measurements of gas flux (CO2, CH4, N2O) in canopy soils of NUMEX plots on four dates (Sept/Nov 2011 and Jan/April 2012). Measurements were taken in 3 of the 4 NUMEX blocks at each elevation; treatments measured included C, N, NP and P.
Additional info:	Gas fluxes were measured by incubating intact soil... Additional info: Gas fluxes were measured by incubating intact soil cores. Gas samples were analyzed on a gas chromatograph with a FID and ECD. Note that the units for CO2 are mg CO2-C m-2 h-1 (not g CO2-C).
