Future works and perspectives
➢ Field surveys using geophysical methods
and isotopic campaigns (streamflow,
groundwater, soil and plant).
➢ Visible and near infrared spectroscopy
(UAV) for developing site-specific PTFs.
➢ Integrating ground-based (SoilNet wireless
sensor networks, Cosmic Ray sensors)
with remote-based (Sentinel-1)
measurements of soil moisture.
➢ Sharing our data set in ENOHA portal with
other TERENO observatories across
Europe.
