| Zusammenfassung |
| Following the launch of the European Space Agency's Soil Moisture and Ocean
Salinity (SMOS) mission on 2 November 2009, SMOS soil moisture products need to be
rigorously validated at the satellite's approximately 45 km scale and
disaggregation techniques for producing maps with finer resolutions tested. The
Australian Airborne Cal/val Experiments for SMOS (AACES) provide the basis
for one of the most comprehensive assessments of SMOS data world-wide by
covering a range of topographic, climatic and land surface variability within
an approximately 500 × 100 km2 study area, located in
South-East Australia. The AACES calibration and validation activities
consisted of two extensive field experiments which were undertaken across the
Murrumbidgee River catchment during the Australian summer and winter season
of 2010, respectively. The datasets include airborne L-band brightness
temperature, thermal infrared and multi-spectral observations at 1 km
resolution, as well as extensive ground measurements of near-surface soil
moisture and ancillary data, such as soil temperature, soil texture, surface
roughness, vegetation water content, dew amount, leaf area index and spectral
characteristics of the vegetation. This paper explains the design and data
collection strategy of the airborne and ground component of the two AACES
campaigns and presents a preliminary analysis of the field measurements
including the application and performance of the SMOS core retrieval model on
the diverse land surface conditions captured by the experiments. The data
described in this paper are publicly available from the website:
