1. NAFE monitoring stations O. Merlin, J. Walker, R. Panciera, R. Young and M. Rinaldi 3 rd NAFE Workshop 17-18 Sept. 2007

2. Objectives Provide 0-5cm soil temperature T eff Derive TIR-T eff relationships Estimate of vegetation wetness Presence of dew

3. Requirements Distributed in space Include major land covers: dry land pasture, irrigated pasture, dry wheat, irrigated wheat, bare soil

4. NAFE stations S1 S2 S3 S4 S5S6

5. 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

6. 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

7. S1 S2 S3S4

8. S1 Dry wheat Breakdown of the TIR

9. S2 Bare soil No veg wetness sensor

10. S3 Irrigated wheat Battery

11. S4 Irrigated pasture (alfalfa) Battery

12. S5 Dry land pasture Logger No radiometer

13. S6 Dry land pasture No logger No radiometer

14. Conclusions Gaps in the data Combination of S1, S5, S6: continuous monitoring for dry land
