CAWCR wave hindcast extension Jan 2011 - May 2013
Ocean wave hindcast, using the WaveWatch III v4.08 wave model forced with NCEP CFSv2 hourly winds and daily sea ice, January 2011 - May 2013.
The dataset contains spectral wave output at 3683 points, as well as gridded outputs on a global 0.4 degree (24 arcminute) grid, with nested Australian and western Pacific subgrids of 10 and 4 arcminutes re... moresolution. For further information, see Durrant et al (in prep)**.

The hindcast was performed using the WAVEWATCH III(TM) model version 4.08. The model was run on a 0.4 x 0.4° global grid with a series of nested grids of 10 arcminutes (~18km) down to 4 arcminutes (~7km) in the Western Pacific and Australian regions. Wave spectra were discretised over 29 frequencies exponentially spaced from 0.038 Hz to 0.5 Hz and 24 directions with a constant 15° directional resolution. All grids were forced with Climate Forecast System Reanalysis v.2 (CFSv2) surface winds at 0.2° spatial and hourly temporal resolution. Hourly sea ice concentrations from the CFSv2 data set were also used to define the ice edge.
Data output in NetCDF4 format.
CAWCR Wave Hindcast pre-June 2013 ERRATA
Wave data pre-June 2013 was created with an early release of WAVEWATCHIII (v4.08).
Note that pre-June 2013 variable 't' should not be used.
Pre-June 2013, Variable ‘t’, named mean wave period using the first spectral moment is a duplicate of variable ‘tm0m1’ mean wave period using the first inverse spectral moment.
Post-June 2013 (inclusive), Variables ‘t01’ represent mean wave period using the first spectral moment, and ‘t0m1’ represents mean wave period using the first inverse spectral moment with no issues.
Several other variable names changes took place during the upgrade.

The Centre for Australian Weather and Climate Research (CAWCR) is a partnership between the Bureau of Meteorology and CSIRO.
Hindcast modelling undertaken as part of the PACCSAP (Pacific-Australia Climate Change Science and Adaptation Planning) Project 4.3 "High resolution wind-wave climate and projections of change in the Pacific region for coastal hazard assessments" in 2012. This project was funded by DCCEE and AusAID and undertaken jointly by CSIRO and the BoM.
Model run on the Bureau of Meteorology SOLAR facility.
