Observations: Wind speed options

[DamienIrving]

Options for wind speed might be:

• AWRA
• SILO (Zhang et al 2022)
• Multi-Source Weather (MSWX) (Beck et al 2022)

According to the AWRA v7 technical report, spatially interpolated site based daily wind run observations are used for daily average wind speed from 1975 onwards, when sufficient site observations were collated by the Bureau (see McVicar et al., 2008 for details of the interpolation approach). A daily varying wind speed climatology value is used, based on the period 1975-2017 when there is no data available (ie. prior to 1975). This differs from AWRA-L v5 and previous versions where this daily data was averaged temporally to generate a single daily average value that applied at all timesteps.
