Soil Moisture Active Passive Experiment (SMAPEx)
headline bar

 

         Field campaigns with airborne and ground data to contribute to the development of radar-only and combined radar-radiometer soil moisture retrieval algorithms for SMAP.

         Utilizes existing in situ resources and enhancements in the Murrumbidgee catchment (NSW) designed to support the unique products of SMAP.

         Introduction of a new low-cost active and passive L-band airborne facility

         Calibration and scaling of an Australian cal/val site for post-launch validation of SMAP products over Australia

         Led by Jeff Walker (University of Monash) and Rocco Panciera (University of Melbourne)

 

Experiment Design

 

         Timing: 4, 1-week long campaigns across one seasonal cycle

         Study area: Semi-arid, irrigated & dryland cropping, dryland grazing

         Airborne: L-band radiometer & radar, VIS/IR/NIR/SWIR and Thermal IR

         Ground: soil moisture, vegetation biomass/VWC/LAI/VIS&NIR, surface roughness, soil temperature

         Monitoring Network: 29 semi-permanent soil moisture stations (on SMAP 36km/9km/3km nested grids)

 

Schedule

 

         Campaign 1:     July 5-July 9, 2010

         Campaign 2:     Dec. 4-Dec. 8, 2010

         Campaign 3:     TBD, 2011
