Summary
Description
Synthetic evaporation data are used to supplement observed Class A pan evaporation data. Synthetic data are required owing to the limited availability of observed data, particularly in the years prior to 1970. Multiple regression was used to construct a model for estimating evaporation from a linear combination of solar radiation and vapour pressure deficit. The model was fitted using observational records from 1975-2003 which had been analysed to eliminate suspect data.

Summary
Description
Observed air pressure is the atmospheric air pressure at the location of the recording station. The spatial variation in observed pressure can be reduced if the topographic component is removed. The observed 9am station level pressure is converted into mean sea level pressure to support biophysical modeling, using the expression given in Jeffrey et al (2001).

Summary
Description
The solar radiation data provided by SILO are an estimate of the total incoming solar energy incident upon the Earth's surface at a given location. The estimate includes contributions from both the direct and diffuse components of solar exposure. It can be calculated from data measured directly by radiometers and indirectly from observational estimates of cloudiness and hours of sunshine duration.

In the context of meteorological data, vapour pressure is the partial pressure of water vapour in the atmosphere. It is calculated by the Bureau of Meteorology from the dew point temperature recorded at 9am.

Summary
Description
The Patched Point Dataset (PPD) combines observations and interpolations to provide daily data for a selected set of stations (locations). The term 'patched' means that if on any day a station does not have an observation then the gap in the record is 'patched' (ie. filled) with an estimate obtained by spatial interpolation of the daily data from surrounding stations. Consequently the Patched Point Data for a given location always contain a complete data record, or in other words, there are no missing data.

Queensland's stock route network (SRN) provides pastoralists with a means of moving stock 'on the hoof' around the state's main pastoral districts, as an alternative to trucking and other contemporary transport methods.Approximately 72 000 kilometres (2.6 million hectares) of Queensland's road network is declared as stock route. These routes, together with reserves for travelling stock, make up the Queensland SRN.The Land Protection (Pest and Stock Route Management) Act 2002 (Land Protection Act) regulates the use of the SRN.

The Department of Natural Resources, Mines and Energy (DNRM) Surface Water Ambient Water Quality Network (SWAN, WQ) (dataset WM1112) monitoring includes either time series (continuous) measurements via electronic sensors, or discrete water sample collection which is laboratory analysed, or a combination of both. This relies on long term monitoring over the full range of flows, so that the effects of seasonality, extreme flow events and non-uniform variance are accounted for.

Description
Foliage Projective Cover (FPC) is the percentage of ground area occupied by the vertical projection of foliage. The Remote Sensing Centre FPC mapping is based on an automated decision tree classification technique applied to dry season (May to October) Landsat-5 TM and Landsat-7 ETM imagery for the period 1988-2012. The wooded extent product has a nominal accuracy of 85%. The field data used to calibrate the imagery/FPC relationship was mostly collected over the period 1996-1999. Corrections have been applied to remove errors due to topographic effects, cloud, cloud shadow, water, cropping, and regrowth following clearing. Some errors may remain. The product was generated from WRS-2 path/row scenes obtained from the United States Geological Survey (USGS). While some land cover change may be detected in the FPC processing, this product is not designed to generate clearing or regrowth following clearing layers, and should not be used to assess clearing or be compared with previous years for change monitoring without consideration of the error. The Statewide Landcover and Trees Study (SLATS) produces accurate clearing layers for this purpose.
