NAFE’05 soil moisture objectives

• Top 5cm water content spatial monitoring using Stevens Water Hydra probe®;

• Farm scale monitoring at multiple resolutions (6.25m to 1km), every 2-3 days;

• Regional scale monitoring at low resolution (1km), weekly.

Conclusions• NAFE’05 soil moisture sampling objectives achieved:

- multi-resolution

- spatial coverage

- temporal coverage

• Data collected show sensible correlation with land surface features (veg

biomass, soil texture, topography etc…)

• Validation of PLMR soil moisture product

• Analysis of PLMR brightness temperatures scaling properties and relation with multi-scale ground data

• Development and testing of downscaling technique for SMOS application

• Improvement of soil moisture retrieval techniques from multi-angle passive microwave observations

Future work

How can we do better in NAFE’06?

• Pole too flexible in hard soil 

• Loose cables

• Loose electrical connections

• Heavy battery

• Prongs bended by stones

• iPaq software errors

• Missing data

Different material

More compact design

Permanent connections

Smaller battery

???

Improve software stability

Daily data processing/check

Problem Possible Solution
