SeaDAS Data Processing Programs

SeaDAS includes a variety of data processing programs accessible via the SeaDAS GUI, the SeaDAS command-line, and the Unix command-line. Using the GUI can be a good way to learn a processing program's functionality, however, using the SeaDAS command-line or Unix command-line is generally more efficient and can be used to automate data processing. Many SeaDAS Unix utility commands are also available.

CAUTION! Our data processing programs can be run either from within SeaDAS using IDL commands, or outside of SeaDAS using Unix commands. The syntax for both the IDL and Unix formats are similar, but there are important differences! This can cause confusion. See this page for more information on the differences.



To standardize program names, as of SeaDAS 5.2 many programs have been renamed. These changes are summarized here and are also noted in the table below.

&Dagger The ms_met.csh, ms_ozone.csh, and ms_oisst.csh Unix shell scripts can be used to determine and retrieve optimal ancillary data for use with the l2gen Unix binary. (The
     functionality of these three scripts is built into the l2gen IDL function.)
