Field campaigns and data sets

The existing long-term soil moisture network (OzNet) together with the variability in natural features across the study area has made this experimental site the focus of the following extensive campaigns:

SMAPEx

Soil Moisture Active Passive Experiments

The Soil Moisture Active Passive Experiments (SMAPEx) comprises a series of five campaigns across an approximately six year timeframe. The overall objective of SMAPEx is to develop algorithms and techniques to estimate near-surface soil moisture from the Soil Moisture Active Passive (SMAP) mission developed by NASA, and validate downscaled SMAP brightness temperature observations and soil moisture products after its launch. This involves collecting airborne SMAP-type data together with ground observations of soil moisture and ancillary data for a diverse range of conditions.

AACES

Australian Airborne Cal/val Experiments for SMOS (AACES)

The Australian Airborne Cal/val Experiments for SMOS (AACES) comprises a set of two separate field campaigns which each combined extensive airborne and ground based data collection across the Murrumbidgee River catchment in 2010. A significant component of this project was developing and testing the soil moisture retrieval algorithms to be used by the Soil Moisture and Ocean Salinity (SMOS) mission and verifying the SMOS data for Australian conditions.

NAFE

The National Airborne Field Experiment (NAFE) comprises of two field campaigns during 2005 and 2006, with the aims to provide access to a wide range of airborne and ground-based monitoring data in support of soil moisture remote sensing, and to extend scope and application to a range of related scientific fields, including hydrology, ecology and atmospheric sciences.
