Cone index and surface soil moisture measurements in selected agricultural fields within the Raam and Twente soil moisture monitoring networks

This dataset covers cone index and surface soil moisture measurements over selected agricultural fields, which are also the sites of a few stations within the Raam and Twente soil moisture monitoring networks. A penetrologger (Eijkelkamp) with 1 cm diameter and 60 degree angle was used to collect cone index over the topsoil (upper 20 cm layer) and a TDR (TRIME-IMKO) was used to collect surface soil moisture (upper 5 cm layer). The data set covers 2016 and 2017 growing seasons.
