Mixed layer depth, isothermal layer depth, barrier layer depth, and other upper ocean thermohaline parameters, total of 17, derived from climatological gridded vertical profiles from the World Ocean Atlas 2018 (NCEI Accession 0205198)

This dataset contains mixed layer depth, isothermal layer depth, barrier layer depth, and other upper ocean thermohaline parameters, total of 17, derived from climatological gridded vertical profiles from the World Ocean Atlas 2018. This global ocean climatological dataset also includes two identity-indices for determining isothermal layer (ITL) depth (ILD) and mixed layer depth (MLD) from gridded (0.25 degree, and 1 degree) temperature and salinity fields of the National Centers for Environmental Information (NCEI) World Ocean Atlas 2018. 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. Data are in netcdf format, one file on a 1deg grid and one file on a quarter degree grid for each calendar month.
