The data are flat binary files (no
headers) consisting of single-precision floating-point numbers.
The data were written as unformatted direct access files on a
Linux PC cluster. Byte order may have to be changed if you are
using a machine using a different byte order (e.g. HP workstations
). A FORTRAN program demonstrating how to read sea ice thickness
and velocity and grid information is provided (read_hi_uice.f).
An
IDL
program demonstrating how to read scalar fields and grid
information is also provided (read_draw_hi.pro).
Another
IDL
routine (read_draw_uice.pro)
is provided to read vector fields and vector grid
information. It also plots ice velocity on a spherical coordinate
system using the angle between the latitude line and the
grid cell x-coordinate line (alpha.fortran.dat).
The
structure
of the data sets should be apparent from these routines. Please
let us know if you have difficulty reading the data.
Data Access:
You can access the data via SFTP by entering 'sftp
anonymous@pscfiles.apl.uw.edu', then 'anonymous' as your password.
After entering the web site, go to /pscfiles/zhang/PIOMAS.
You can also access the data from here: https://pscfiles.apl.uw.edu/zhang/PIOMAS/
If you are downloading the data, please e-mail us at zhang@apl.washington.edu
we can update you on changes, bugs etc.
