Dear all
The following data represents the output of numerical model
and consists of 42 lines header with 9 time intervals air masses back
trajectory.
each interval consists of 3 columns as follows ( time in SECS
LONGIT LATIT)
Please note that, each intervals are not regular in number of
recorders.
Just I would like to read each interval for later plotting on a map,
Thank you very much for any suggestions
42 Number of header
lines
