Each summary file has data on up to three different variables which are listed in the last column.

 

Metadata: web file

Draft, Thickness, or Freeboard Summaries
Each file begins with one header line identifying the variables. The variables are listed in the table below. The header and data formats are
hdr_fmt = '( 2a12, a10, 6a9, a6, a10, 4a8, 2a8, a10, 3(4a10) ) '
data_fmt = '( 2a12, i10, 6f9.3, i6, f10.1, 4i8, 2f8.1, i10, 3(4f10.1) '

Ice Thickness Distribution Files
Each file begins with one header line identifying the variables. The variables are listed in the table below with typical values of the number of bins, bin width, and first bin in brackets. The header and data formats are
hdr_fmt = '(2a12, a10, 2a9, 6a8, 2a8)'
data_fmt = '(2a12, i10, 2f9.3, 6i8, 2f8.2, 300f7.4 )'
