Fort.93: Ice Coverage Fields at All Nodes

This file contains ice coverage field data at all nodes in the model grid. The file follows the same format as the Pressure and Elevation files. It is generated only when ice fields are activated and global meteorology output is enabled through the parameters (NOUTGW, TOUTSGW, TOUTFGW, NSPOOLGW) in the Model Parameter and Periodic Boundary Condition File.

File Structure

The file can be written in either ASCII or binary format, depending on how NOUTGW is set in the Model Parameter and Periodic Boundary Condition File. The basic structure is shown below:

RUNDES, RUNID, AGRID
NDSETSW, NP, DTDP * NSPOOLGW, NSPOOLGW, IRTYPE
TIME, IT
for k=1, NP
    k, iceCoveragePercent(k)
end k loop

Notes

  • Output format (ASCII/binary) is determined by NOUTGW in the fort.15 file

  • For binary output, the node number (k) is not included in the output

  • Time series data is recorded for every node in the model grid

  • The output frequency is controlled by NSPOOLGW parameter

  • Output timing can be further controlled using TOUTSGW (start time) and TOUTFGW (end time)

  • The variable iceCoveragePercent represents the percentage of ice coverage at each node

  • File structure matches the format used in fort.73 (pressure) and fort.63 (elevation) files
