  • Project Overview

    Its purpose is to obtain data for validation of GCOM-W1 soil moisture products, which are components of a land surface data assimilation system. These data systems are important for land surface models, which rely on atmosphere-surface observations. Information provided by an existing network of soil moisture monitoring systems will also be used to validate the GCOM-W1 soil moisture product. The tower will provide longterm measurements as part of the Ozflux network .

    Key research aims

  • To provide additional validation data for use in land surface data assimilation. These data systems are important for land surface models, which rely on atmosphere-surface observations.
  • For validation of the Advanced Microwave Scanning Radiometer-2 (AMSR2) soil moisture product and resulting soul moisture and flux estimates.
  • For crop modelling, runoff, flood forecasting, Land Surface Model forcing data (i.e. input of AMSR2 soil moisture into the Joint UK Land Environment Simulator (JULES) model).
  • The Site Location

    The flux tower monitoring system is located within the Yanco region of New South Wales, Australia (Latitude: -34.99 S Longitude: 146.29 E). The Yanco area of the flux tower site is located in the western plains of the Murrumbidgee Catchment and is within a wider research area (60 x 60 km) that supports a network of OzNet stations, which have been in operation since late 2001 onwards.

    Site Characteristics

    The Yanco area of the flux tower site is located in the western plains of the Murrumbidgee Catchment. This is a topographically flat area, primarily comprised of the following soil types: sandy loams, scattered clays, red brown earths, transitional red brown earth, sands over clay and deep sands. Stream valleys and layered soil and sedimentary materials are found across the landscape.

    The tower on site extends to 20m, however flux measurements are recorded from slightly lower than this (see measurements table for more details). Mean annual precipitation from a nearby Bureau of Meteorology site measured 465 mm. Maximum temperatures ranged from 37.4ºC (in January) to 16.6ºC (in July), while minimum temperatures ranged from 29.0ºC (in January) to 11.8ºC (in July). Maximum temperatures varied on a seasonal basis by approximately 20.8ºC and minimum temperatures by 17.2ºC.

    Data

    Data from this site is available through the OzFlux data portal international FLUXNET database or via the investigators email jason.beringer[@]uwa.edu.au

    Yanco MODIS data

    The data was obtained from the Oak Ridge National Laboratory Distributed Active Archive Center for Biogeochemical Dynamics (ORNL DAAC) (http://daac.ornl.gov/MODIS/). The ORNL DAAC provides MODIS Land Product Subsets for model validation, site characterisation and remote-sensing purposes.

    Daily updated data was obtained from this provider, with an area of 3x3km extracted using Python script written by Mr. Darien Pardinas-Diaz (darien.pardinas-diaz@monash.edu). The plots were produced using QC Filter Conditions 000 and 001. Condition 000 represents the highest QC Filter possible and 001 represents a reliable and usable QC Filter, though not to the standard of 000.
