Service Description: Operational modelled long-term historical landscape water balance variables from the Bureau of Meteorology’s Australian Water Outlook (awo.bom.gov.au).

This endpoint allows you to access the modelled long-term historical outputs of the Bureau’s Australian Water Resources Assessment – Landscape (AWRA-L) hydrological model, including precipitation and modelled soil moisture, evapotranspiration (potential and actual), runoff and deep drainage, from 1911 until yesterday.

The AWRA-L model is a daily 0.05° grid-based, distributed water balance model, conceptualised as a small unimpaired catchment. It simulates the flow of water through the landscape with precipitation entering the grid cell through vegetation and soil moisture stores and then out of the grid cell as evapotranspiration, runoff or deep drainage to the groundwater.
The following modelled hydrological variables are accessible via this end-point:

asce_pet: Reference crop evapotranspiration - Tall (mm)
dd: Deep Drainage (mm)
e0: Modelled landscape potential evapotranspiration (mm)
etot: Modelled landscape actual evapotranspiration (mm)
fao_pet: Reference crop evapotranspiration - Short (mm)
ma_wet: Areal potential evapotranspiration (mm)
msl_wet: Open water evaporation (mm)
pen_pet: Synthetic pan evaporation (mm)
qtot: Runoff (mm)
rain_day: Precipitation (mm)
s0_pct: Upper soil moisture (0-0.1m depth) (% full)
sd_pct: Deep soil moisture (1-6m depth) (% full)
sm_pct: Root zone soil moisture (0-1m depth) (% full)
ss_pct: Lower soil moisture (0.1-1m depth) (% full)

This end-point provides the modelled outputs in modelled absolute units, per the list above.

Regarding the soil moisture variables: the water contents are estimates of the available water content for each modelled time-period. Where % full units are used, these provide the data as a percentage of the overall water holding capacity to soil saturation.

If you would like to access the modelled values in terms of relative percentiles compared to long-term climatological records, please see the end-point in this portal titled:

AWO Modelled Historical Water Balance Variables - Daily (2005-2019) - Relative Percentiles, CRF

For more information about how these modelled variables were produced, and how to interpret them, please see the About historical page on the AWO website. That page also contains links to detailed technical reports and scientific journal articles.
