RD Instruments 1200 KHz ADCP File Formats:


adcp_YYYYMMDD.dat --> RD Instruments HexAscii format, velocity & echo amp


adcp_YYYYMMDD.frm --> Formatted data from above:

    Header line:
      yyyymmdd hhmmss  ttt.tt  hhh.hh ppp.pp rrr.rr  ssss.s  bbb

    Data line (1 for each bin):
      eeee.e nnnn.n vvvv.v rrrr.r  aaa bbb ccc ddd

    where: yyyymmdd = date at start of sample (year,month,day)
       hhmmss   = time at start of sample (hour,min,sec)
       ttt.tt   = temperature (C)
       hhh.hh   = compass heading (deg)
       ppp.pp   = pitch angle (deg)
       rrr.rr   = roll angle (deg)
       ssss.s   = speed of sound (m/s)
       bbb      = number of bins

       eeee.e   = east velocity (cm/s)
       nnnn.n   = north velocity (cm/s)
       vvvv.v   = vertical velocity (cm/s)
       rrrr.r   = error velocity (cm/s)
       aaa      = echo intensity on bin 1
       bbb      = echo intensity on bin 2
       ccc      = echo intensity on bin 3
       ddd      = echo intensity on bin 4

       Note: velocity values of -999.9 indicate invalid data
