Thermosteric Sea Level Anomaly: Basin time series

The time series of yearly, pentadal, and 3-month thermosteric 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 thermosteric 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 anomaly

1955 - 2022 (0 - 700 meters)
2005 - 2022 (0 - 2000 meters)

Pentadal anomaly

2005 - 2022 (0 - 2000 meters)

3-Month anomaly

1955 to present (0 - 700 meters)
2005 to present (0 - 2000 meters)

File naming conventions:

a-mm-[Y]0-[Z]m[X1-X2].dat where:

a-mm
- the label for thermosteric 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 'a-w0-700m1-3.dat' contains the time series of ocean 3-month (Jan-Mar) heat content of the 0-700 m layer for the World Ocean

THERMOSTERIC SEA LEVEL ANOMALY (TSLA) 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.

1st column - year+0.5 (for the yearly heat content)
2nd column - time series of TSLA of OB;
3rd column - time series of the standard error of TSLA of OB; 4th column 4th column - time series of TSLA of NHPB;
5th column - time series of the standard error of TSLA of NHPB;
6th column - time series of TSLA of SHPB;
7th column - time series of the standard error of TSLA 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.
