Walker, Merlin, Panciera, Kalma and Hacker NAFE National Airborne Field Experiment 2 nd Workshop – Feb

Walker, Merlin, Panciera, Kalma and Hacker Welcome Jeffrey Walker, Olivier Merlin and Rocco Panciera Dept of Civil and Env Engg The University of Melbourne, Australia Jetse Kalma School of Civil, Surveying and Env Engg The University of Newcastle, Australia Jorg Hacker Airborne Research Australia Flinders University, Australia

Walker, Merlin, Panciera, Kalma and Hacker Background Campaigns are not planned as big integrated and highly structured campaigns (such HAPEX etc.) with unified themes. Campaigns are designed to give people access to airborne monitoring and ground- based monitoring data in return for contributing to ground-based monitoring programs. Each participant would be expected to sign up for at least 2 weeks and contribute 50% of their time to soil moisture monitoring program (i.e. mornings or afternoons)

Walker, Merlin, Panciera, Kalma and Hacker Purpose of Today What are your science questions and data needs? What is the best study are to address these diverse needs – Goulburn, Murrumbidgee, Other? What ground monitoring plan will best address these needs? What flight pattern and instruments will best address these needs?

Walker, Merlin, Panciera, Kalma and Hacker Our Questions Spatial, temporal and accuracy requirements for satellite missions Development and validation of passive microwave algorithms – AMSR-E/SMOS/ Hydros – scaling, multiangle, etc Downscaling of low resolution passive microwave soil moisture measurements using high resolution visible/thermal data and/or radar (ie Hydros) Retrieval and validation of derived root zone soil moisture from the assimilation of near- surface measurements

Walker, Merlin, Panciera, Kalma and Hacker Our Ground Requirements Long-term monitoring of soil moisture profiles and associated meteorological data for modelling and evaluation of root zone soil moisture Extensive ground-based measurement of near- surface soil moisture and ancillary data (veg water, roughness etc) across individual farms at during airborne monitoring campaigns for aircraft validation and scaling, algorithm development, downscaling and mission requirements Continuous near-surface soil moisture, soil temperature, and thermal infrared logging at focus farms for relating air/ground measurements

Walker, Merlin, Panciera, Kalma and Hacker Our Air Requirements Fly with passive microwave, thermal and NDVI scanner would also like lidar scan and digital photography (once) Air measurements coinciding with ground measurements, as early in the morning as possible soil and veg temperatures are more closely aligned more uniform soil temperature profile Hydros/SMOS have 6am/pm overpass; AMSR-E has 1am/pm overpass Fly at a range of altitudes to achieve a range of ground resolutions provides data for scaling, root-zone, algorithm development/validation and mission requirements 50m at 500ft (farms) to 1km at 10,000ft (regions) for microwave 1m at 500ft to 20m at 10,000ft for thermal & NDVI Fly farms with instrument in multiangle configuration Provides data for SMOS algorithm development

Session 1: What are the questions and requirements of our collaborators?

Walker, Merlin, Panciera, Kalma and Hacker Some Absentee Interests Marc LeBlanc and Sarah Tweed, Monash Uni What science questions you would like to address: Groundwater application, for example testing the SEBS ET algorithm and determine the groundwater application from soil moisture and other datasets. What data you need to answer them: map of thermal, NDVI, meteorological data, groundwater monitoring data John Hornbuckle, CSIRO extensively monitored irrigated vineyard in the Murrumbidgee Irrigation Area near Griffith – spatial soil and canopy NDVI/leaf temp measurements, enviroscans, bowen ratio energy balance systems etc and would be interested in doing some comparison work
