East Asian Seas Regional Climatology

The East Asian Seas Regional Climatology Version 2.0 is an update to the preliminary May 2012 release, and includes new temperature and salinity data spanning from 1804 through 2013. The climatology is a set of objectively analyzed climatological fields of temperature and salinity at standard depth levels in the East Asian Marginal Seas.

East Asian Seas

These decadal climatologies were generated from regional data in the World Ocean Database. The datasets used are described in WOD 2013.

Study Area

115°E to 143°E longitude and 24°N to 52°N latitude

Temporal Resolution

Each climatology has an annual (all-data), seasonal, and monthly time period calculation.

Seasons

Winter (Jan.-Mar.), Spring (Apr.-Jun.), Summer (Jul.-Sep.), Fall (Oct.-Dec.)

Horizontal Resolution

Temperature and salinity are available on a 1x1, 1/4, and 1/10 latitude/longitude degree grid.

Vertical Resolution

Annual and seasonal climatologies are available from the surface to 5500 meter depths. Monthly climatologies are available from the surface to 1500 meter depths.

Units

Temperature
°C
Salinity
Unitless on the Practical Salinity Scale-1978 [PSS]
Data distribution
Units are in number of observations in each grid box.

Bathymetry

One-degree and 1/4-degree
The mean of an ETOPO2 grid square
1/10th-degree
The mean of an ETOPO1 grid square

Method

The methods used for calculating the mean climatological fields is described in Locarnini et al., 2013 for temperature and Zweng et al., 2013 for salinity. Additional details on the 1/4° climatological calculation are found in Boyer et al., 2005. Table 1 gives radii of influence for all three passes through the objective analysis procedure for each horizontal resolution.

Pass 1° radius of influence 1/4° radius of influence 1/10° radius of influence
1 892 km 321 km 211 km
2 669 km 267 km 155 km
3 446 km 214 km 111 km
