Seasonal Variability of Dynamic Height and its Fourier Analysis
by Sydney Levitus, Grigory Isayev Monterey, and Timothy Boyer

These files contain climatological monthly mean dynamic height (dynamic-cm) of the sea surface relative to 1000 m depth level. Dynamic heights are computed according to the formula from Levitus (1982) and updated using the UNESCO equation of state. The units are dynamic centimeters. An atlas showing these fields, as well as deviations from the climatological annual means, and results from their Fourier analyses, are available from the NNDC Online Store.

Download data (also, available the FORTRAN program and the co-ordinate system for reading the data)
Monthly dynamic heights (0/1000 m) for the World ocean are in 12 direct access files on a 1*1 degree grid.
The files are named dh.001,... dh.012.

dh.001 dh.002 dh.003 dh.004 dh.005 dh.006
dh.007 dh.008 dh.009 dh.010 dh.011 dh.012
