| Description: | Soil heat flow #4 was replaced at the beginning of this period. However, the soil heat
flow measurements from that sensor were sometimes still lower than the lower limit imposed
in the EBBR programming; sensible and latent heat flux were therefore deemed to be
suspect during those times. The cause of the low values could not be determined, but the
values are not reasonable for the vegetation type at EF18.
To remedy the situation, the soil heat flow sensor calibration was changed so that the
sensor provided measurements that resembled the other four soil heat flow sensor
measurements.
Soil heat flow measurements have been reasonable since the calibration change. |
