Before using any of these PSMSL data files, please appreciate the differences between 'Metric' and 'RLR' data values.
After switching to a new database structure in 2010, the formats associated the following files no longer adequately represent the data in the database. For example, latitudes and longitudes are now kept to an accuracy greater than one minute. Thus, the files below are records of the last update of these files prior to the switch to the new database (29 Mar 2010). They are no longer updated.
The complete PSMSL data set of monthly and annual mean values of sea level (psmsl.dat), an associated information file describing the format of the file (psmslrd.hel), and a fortran job which can read the data file (psmslrd.f) can be download from here:
A much smaller file containing only annual mean values from the PSMSL RLR data set (rlrann.dat), an associated information file describing the format of the file (rlrannrd.hel), and a fortran job which can read the data file (rlrannrd.f) can also be download from here:
PSMSL help file contains a description of the format of these printout files.
