added data in netcdf format (SF_nc)

UPDATE2018-02-08
UPS_BiogenicSoilFluxes.dat was modified to provide daily fluxes and standard deviations of soil NO and NH3, and to correct for chemical reactions inside the chamber as explained in Pacifico et al.

Description du jeu de données
RésuméBiogenic soil fluxes of NO and NH3 measured at the Save site
Strategie d'observationThe technique used to measure NO and NH3 soil fluxes makes use of a Thermoscientific 17i (ThermoFischer Scientific, MA, USA) to measure the concentration of NO and NH3 through chemiluminescence, and the closed dynamic chamber technique to calculate fluxes. The details of this technique are fully described in Delon et al. (2017).

The instrument was powered by a generator and carried around on a wheeled-table to reach the locations of the four soil types where the NO and NH3 soil fluxes were measured.
The analyzer was attached to a teflon tube and teflon chamber which was put on the ground to detect the fluxes.

The four land cover types were the measurements were taken are: bare soil, grassland, maize field and forest.
