Global Ocean Climatology - Density Climatology

The SDC_GLO_CLIM_Dens product contains global monthly climatological estimates of in situ density using Temperature and Salinity from profiling floats contained in the World Ocean Data 18 (WOD18) database. The profiles were first quality controlled with a Nonlinear Quality control procedure. The climatology considers observations from surface to 2000 m for the time period 2003-2017. Density profiles are computed using UNESCO 1983 (EOS 80) equation from in situ temperature, salinity and pressure measurements by the PFL. Only profiles with both T,S values were used.

The gridded fields are computed using DIVAnd (Data Interpolating Variational Analysis) version 2.3.1.

Statement

In this product, first the basic WOD quality flags (QF) has been considered. There are three types of QFs in the WOD:


1-Orginator Flag (Oflag)


2-World Ocean database observed value flag (WODf)


3-World Ocean database profile flag (WODpf)


In this analysis, only the observations with WODf flags value “0” (Accepted) and WODpf flag value “0” (Accepted) have been used.


An additional quality control, a nonlinear quality control developed by Shahzadi (2020) has been implemented with the following assumptions:


1- The domain is divided into 5x5 degree boxes, where mean and standard deviations(std) are computed.


2- Data is eliminated outside 2 std in each box and procedure is repeated.
