The model covers 78°S to 80°N with a regular 0.5° grid, a spectral grid with 36 frequencies (XFR=1.1 starting at f1= 0.0339) and 24 directions. This hincast uses consistent wind forcing from ERA5 (Hersbach et al. 2020) and different forcing for currents, ice and icebergs depending on their availability over the years: 1991 : CCI_ERA5_ERA5_NOCUR_T702_04 1992 : CCI_ERA5_SSMI_NOCUR_T702_03 1993-2020 : CCI_ERA5_CERSATSSMI_MERCAREA_T702_01 2021-2023 : CCI_ERA5_CERSATSSMI_MERCAFOR_T702_02 2024 : CCI_ERA5_SSMI_MERCAFOR_T702_07 switch choices: SCRIP SCRIPNC TRKNC DIST MPI PR3 UQ FLX0 LN1 ST4 STAB0 NL1 BT4 DB1 MLIM TR0 BS0 IC2 IS2 REF1 WCOR WNT2 WNX1 RWND CRT1 CRX1 Parameters settings: &SIN4 BETAMAX = <betamax>, SWELLF = 0.66, TAUWSHELTER = 0.3, SWELLF3 = 0.022, SWELLF4 = 115000.0, SWELLF7 = 432000.00 / &SDS4 SDSBCHOICE = 3, SDSC2 = -3.80, FXFM3 = 20.00, SDSSTRAINA = 0.00, SDSSTRAIN = 0.00, SDSSTRAIN2 = 0.00, SDSBR = 0.005, SDSBT = 0.0011, SDSCUM = 0.300, SDSC5 = 1.0, SDSMWD = 0.00, SDSFACMTF = 400 / &SNL1 NLPROP = 25000000.0 / &OUTS P2SF = 1, E3D = 1, I1P2SF = 1, I2P2SF = 36 / &PRO3 WDTHCG = 1.50, WDTHTH = 1.50 / &REF1 REFCOAST = 0.05, REFCOSP_STRAIGHT = 4, REFFREQ = 1., REFICEBERG = 0.2, REFMAP = 0., REFSLOPE = 0., REFSUBGRID = 0.1, REFRMAX = 0.5 / &SIC2 IC2DISPER = F, IC2TURB = 1.0 , IC2ROUGH = 0.001 , IC2REYNOLDS = 150000, IC2SMOOTH = 200000., IC2VISC = 2.0 / &SIS2 ISC1 = 0.2, IS2C2 = 0.000000, IS2C3 = 0. , IS2BACKSCAT = 1. , IS2BREAK = T, IS2DUPDATE = F , IS2CREEPB = 2E7 , IS2CREEPD = 0.5 / &MISC ICEHINIT = 0.5, ICEHMIN = 0.1, CICE0 = 0.25, NOSW =6, CICEN = 2.00, LICE = 40000., FLAGTR = 4, FACBERG = 0.2 , WCOR1=21., WCOR2=0.5 / END OF NAMELISTS The dataset consists of hourly wave parameters at 0.5deg spatial resolution covering the period 1991 to 2024 The output files are stored by year following the convention which includes the following directories : "FIELD_NC/" folder has the hourly outputs, saved into monthly netcdf files. "data/" folder has all the configuration files including bottom topography, namelist, etc. "work/" folder has preprocessing file descrption used for each run. "output/" folder has description of output field description and others. "SPEC_NC/" folder has spectral energy information at the points listed in "/data/output_points_small_GLOB-30M.txt".
