NAFE monitoring stations O. Merlin, J. Walker, R. Panciera, R. Young and M. Rinaldi 3 rd NAFE Workshop Sept. 2007
Objectives Provide 0-5cm soil temperature T eff Derive TIR-T eff relationships Estimate of vegetation wetness Presence of dew
Requirements Distributed in space Include major land covers: dry land pasture, irrigated pasture, dry wheat, irrigated wheat, bare soil
NAFE stations S1 S2 S3 S4 S5S6
NAFE station set up 1 Mikron FOV 6:1 1 Ahlborn FOV 4:1 2 Everest FOV 1:1 Campbell sensor 0/1 Unidata temp sensors North
TIR calibration 1 before 1 after campaign Add hot water 60ºC in bucket And ice down to 10ºC Link black body temp to output I/V
S1 S2 S3S4
S1 Dry wheat Breakdown of the TIR
S2 Bare soil No veg wetness sensor
S3 Irrigated wheat Battery
S4 Irrigated pasture (alfalfa) Battery
S5 Dry land pasture Logger No radiometer
S6 Dry land pasture No logger No radiometer
Conclusions Gaps in the data Combination of S1, S5, S6: continuous monitoring for dry land
