This data set includes modeled significant wave height and ustar driven by the JRA55-do atmospheric reanalysis product (Tsujino et al. (2018) 'JRA-55 based surface dataset for driving ocean-sea-ice models (JRA55-do)'). The fields are originally created for an application for predicting sea-state dependent air-sea gas transfer velocities, and therefore have been remapped to the pCO2 spatial grid of Landschutzer et al. (2016) for the same time frame ('Decadal variations and trends of the global ocean carbon sink'). The wave height is simulated using NOAA's WAVEWATCH-III surface model on the native JRA55-do grid with the JRA55-do wind input and model simulated monthly sea-ice data. The ustar fields assume neutral stability and use the COARE3.5 algorithm (Edson et al., 2013) to diagnose the stress. For more information on the wave simulation or to inquire about accessing wave data on the native grid and/or for the extended JRA55 time period please contact the author.
