B.1 Foulum Dataset

Extensive measurements of soil water tension, soil water content, soil temperature and soil thermal conductivity were made during an experiment on a $25 m^2$ bare soil plot (Schelde et al., 1998) at the Research Centre Foulum (Denmark). The texture of the topsoil was classified as $60 \%$ sand and fine sand, $29 \%$ silt, $8 \%$ clay and $3 \%$ organic material. Table B.1 summarises the conducted measurements.
