1. Second NAFE Workshop NAFE’06: A Proposed Campaign Strategy J Walker, O Merlin and R Panciera Dept Civil and Env Engg The University of Melbourne, Australia

2. Second NAFE Workshop Objectives NAFE’05 – provide high resolution data for process level understanding of: -soil moisture retrieval -downscaling -and data assimilation. NAFE’06 – provide simulated SMOS data for trial application of: -soil moisture retrieval -downscaling -and data assimilation.

3. Second NAFE Workshop How to meet the objectives? Mimic a SMOS pixel (50 by 50 km 2 ) Provide multi-incidence L-band data for SMOS algorithm development Provide 1 km surface soil moisture data for verification of downscaling approaches using MODIS Provide simulated SMOS data every 2-3 days for data assimilation

4. Second NAFE Workshop Murrumbidgee Catchment Yanco Study Area Kyeamba Creek Adelong Creek Flux Towers

5. Second NAFE Workshop Proposal Yanco area = SMOS pixel Fly PLMR (1km) every 2-3 days over the SMOS pixel Multi-incidence (1km) and high res (50m) PLMR flights over focus areas with range of soil moisture and vegetation cover for: –Algorithm development –PLMR verification

6. Second NAFE Workshop Proposed workplan 1.Aircraft flight lines 2. Coincident ground data collection
