A new thermal technique:

TP01 thermal properties sensor is a thermal probe that is originally
intended for soil thermal conductivity measurements. It has recently been
qualified for measurement of thermal diffusivity.
The primary application of this additional measurement is to estimate the
"storage term" in the soil energy balance.
As such it is used in high accuracy Bowen Ratio stations.

Another interesting aspect, and the reason for sending this message to the
sowacs mailing list,
is that changes in soil thermal diffusivity are directly related to changes
in water content.
Although TP01 is not advertised as a water content sensor, (it does not
have a particularly high absolute accuracy) it might be a useful tool for
use in highly saline soils, or to create some redundancy in the
observations in meteorological measurement stations. The repeatability of
the measurements is very good, so trends can be monitored quite well.
