Hukseflux Thermal Sensors
HFP01SC Manual v0811 page 19/33
Heat flux sensors in meteorological applications are typically
buried at a depth of about 5 cm below the soil surface.
Burial at a depth of less than 5 cm is generally not
recommended. In most cases a 5 cm soil layer on top of the
sensor offers just sufficient mechanical consistency to guarantee
long-term stable installation conditions.
Burial at a depth of more than 8 cm is generally not
recommended, because time delay and amplitude become less
easily traceable to surface fluxes at larger installation depths.
See the appendix for more details.
