4 WERA Wind Direction

  The file name is encoded in yyyydddhhmm_ccc.win_asc with
    yyyy = 2000        (year, 1999, 2000)
     ddd = 032 ... 092 (day within the year, e.g. 01-Feb to 31-Mar)
      hh =  00 ...  23 (hour)
      mm =  00 ...  59 (minutes)
     ccc = nic         (code for experiment, e.g. nic = Nice)
     cur = cur / wav   (cur indicating data set for 'currents')
                       (wav indicating data set for 'waves')

  The time is given in UTC and indicates the center time
  of a 10 minute average.

  The first line gives the number M of HF radar sites
     FORMAT(x,i3)

  The next M lines give:
     date/time of the start of the measurement,
     name of the site,
     LAT / LON of site,
     and 'WERA', indicating this measurement has been
     conducted by the University of Hamburg WERA,
     FORMAT(x,a34,f10.5,a6,f10.5,a17)
 
  The next line is empty.

  The next three lines give the description of the measurement grid
     followed by the actual values:
     LAT(1,1), LON(1,1) -- upper left corner of the grid in degrees
                           West, South -> negative values
     DGT[km]            -- grid spacing in LAT and LON direction in kilometers
     NX                 -- number of grid points in East direction
     NY                 -- number of grid points in South direction
     FORMAT(x,f9.5,x,f10.5,f9.3,2(x,i4))

  The next line is empty.

  The next line gives the number N of data lines in the file to
     follow after the description lines.
     FORMAT(x,i8)
