Global ocean climatological dataset of 17 thermohaline parameters derived from WOA-2023 (NCEI Accession 0290372)

Description

This is the global ocean climatological dataset of 17 thermohaline parameters along with 2 identity-indices for determining isothermal layer (ITL) depth (ILD) and mixed layer depth (MLD) from gridded (0.25 degree, 1 degree, 5 degree) temperature and salinity fields of the National Centers for Environmental Information (NCEI) world ocean atlas 2023. The exponential leap-forward gradient method is used to identify (ILD, MLD) as well as mean thermocline and pycnocline gradients at each horizontal grid point. With the given (ILD, MLD) and mean thermocline and pycnocline gradients, other parameters such as ITL heat content, mixed layer fresh-water content, ITL temperature, mixed layer density, temperature jump, density jump, maximum thermocline gradient, thermocline depth, temperature at thermocline depth, maximum density gradient, pycnocline depth, density at pycnocline depth, ILD minus MLD. The quality measure (I- index) is provided. The data of (ILD, MLD, as well as their derived parameters) are flagged out with the I-index smaller than 0.5. All derived parameters are calculated from WOA-2023 objectively analyzed profile data. Results are in NetCDF.
