12 2 nd NAFE Workshop 13–14 February 2006 g Rocco Panciera High resolution data - Pembroke Soil moisture Aerial photo NDVI  Variable vegetation cover Native grass/ Barley  Microtopography

13 2 nd NAFE Workshop 13–14 February 2006 g Rocco Panciera High resolution data - Stanley Soil moisture Aerial photo NDVI  Microtopography  Uniform vegetation cover

14 2 nd NAFE Workshop 13–14 February 2006 g Rocco Panciera High resolution data - Illogan Soil moisture Aerial photo NDVI  Variable vegetation cover Barley / Oat  Flat topography

15 2 nd NAFE Workshop 13–14 February 2006 g Rocco Panciera High resolution data - Midlothian Soil moisture NDVI  Variable vegetation cover crop / bare soil  Flat topography

16 2 nd NAFE Workshop 13–14 February 2006 g Rocco Panciera High resolution data – Merriwa Park Soil moisture NDVI  Microtopography  Uniform vegetation cover

17 2 nd NAFE Workshop 13–14 February 2006 g Rocco Panciera High resolution data – Cullingral Soil moisture NDVI  Variable vegetation cover Wheat / Barley  Flat topography

18 2 nd NAFE Workshop 13–14 February 2006 g Rocco Panciera 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

19 2 nd NAFE Workshop 13–14 February 2006 g Rocco Panciera 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
