Total Steric Sea Level Anomaly: Basin time series
The time series of yearly and 3-month total steric sea level anomaly are presented for the 0-700 meters and 0-2000 meters layers. There is one file of yearly and four files of 3-month total steric sea level anomaly for each of four major oceanic basins: the World Ocean, the Pacific Ocean, the Atlantic Ocean (which includes the entire Arctic Ocean), and the Indian Ocean. Each file contains the integral for the entire basin (OB), the northern hemisphere part of the basin (NHPB), and the southern hemisphere part of the basin (SHPB). The WOA documentation includes information on downloading and reading the data.
Yearly (1955 to 2023)
Pentadal (1955 to 2023)
3-Month (1955 to present)
- Atlantic:
- 0 - 700, 0 - 2000 meters (Jan-Mar)
- 0 - 700, 0 - 2000 meters (Apr-Jun)
- 0 - 700, 0 - 2000 meters (Jul-Sep)
- 0 - 700, 0 - 2000 meters (Oct-Dec)
-
Indian:
0 - 700, 0 - 2000 meters (Jan-Mar) - 0 - 700, 0 - 2000 meters (Apr-Jun)
- 0 - 700, 0 - 2000 meters (Jul-Sep)
- 0 - 700, 0 - 2000 meters (Oct-Dec)
s-mm-[Y]0-[Z]m[X1-X2].dat where:
s-mm
- the label for total steric sea level anomaly
Y
- ocean basins: w - World, p - Pacific, a - Atlantic, i - Indian
0
- the upper depth of integration ('0' stands for the sea surface)
Z
- the lower depth of integration ('700')
m
- the label refering to depth in meters
X1-X2
- the 3-month period, where: '1-3' for Jan-Mar, '4-6' for Apr-Jun, '7-9' for Jul-Sep, '10-12' for Oct-Dec
dat
- the filename extension
For example:
file 's-w0-700m1-3.dat' contains the time series of ocean 3-month (Jan-Mar)
total steric anomaly of the 0-700 m layer for the World Ocean
Total Steric Sea Level Anomaly (TSSLA) units - mm
Data format:
Data in each file is organized in column form.
Each column corresponds to the time series for ocean basins as outlined below.
2nd column - time series of TSSLA of OB;
3rd column - time series of the standard error of TSSLA of OB;
4th column - time series of TSSLA of NHPB;
5th column - time series of the standard error of TSSLA of NHPB;
6th column - time series of TSSLA of SHPB;
7th column - time series of the standard error of TSSLA of SHPB.
The first line of file contains the labels for each of 7 columns. Read the second line through the last line using an equivalent of the FORTRAN FORMAT (F8.1, 6F8.3) statement.
