The allocation of the variables is shown in the table below. To download the data click on either the ASCII or netCDF link at the head of a column. The ASCII link brings the data to the screen in the ACF format where it can be viewed and saved if desired using "Save As". The netCDF file format is binary and while not directly viewable may be downloaded. The ICARTT file format is the same data formatted to the ICARTT data standard (which is based on the NASA Ames Format).

Most ASCII, netCDF, and ICARTT files for this cruise have a time resolution of 1 minute. If available, one second data files are listed under the link "One Second ICARTT". These one second data files in ICARTT format are zip compressed, but still large, of order 100 Mbytes.

Some data files from recent cruises may be password protected. To obtain a password, please contact Jim Johnson or Timothy Bates.

Moving the cursor over an "Info Icon" and/or clicking provides additional information on the variables.
