CAWCR Wave Hindcast extension June 2013 - July 2014

Ocean wave hindcast, using the WaveWatch III v4.18 wave model forced with NCEP CFSv2 hourly winds and daily sea ice, June 2013 - July 2014. 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 resolution. For further information, see Durrant et al (2014)**. See CSIRO Data Access Portal entry for 1979-2010 data, and for Jan 2011- May 2013 data. 

LineageThe hindcast was performed using the WAVEWATCH III(TM) model version 4.18. 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

CreditInput data: NCEP CFSv2 surface winds and sea ice, Wave model used: WaveWatch III, 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, and extended with support from COSPPAC (Climate and Oceans Support Program in the Pacific). This project was funded by DCCEE and AusAID and undertaken jointly by CSIRO and the BoM. Model run on the Bureau of Meteorology NGAMAI facility.

About this Project:

This output was produced as part of  PACCSAP Project 1.4.3:  High resolution wind-wave climate and projections of change in the Pacific region for coastal hazard assessment.

Project Description: Wave observations will be used to calibrate a wave model which will be used to estimate 21st century wave projections based on from CMIP5 models for different emission scenarios.
