Output parameters:<br /> Year day, lat, long, Speed made good, course made good, gyro 1 &amp; 2, Edo speed, Edo indicator, port wind speed, starboard ws, port wind azimuth, starboard waz, air temp, relative humidity, barometric pressure, sea surface temp @5m &amp; 1m depth, Edo depth, Chirp sonar depth.</li> <li>Put plots of all parameters on screen and look for obvious single bad points. Edit in basic concatenated file. Except I have not edited depths.</li> <li>Iterate steps 2-4 until no more obvious bad points.</li> <li>Run second program which computes true wind speed and direction from speed and course made good, gyros, larger of port or starboard ws and accompanying wind azimuth. Outputs are year day, lat lon, speed and course made good, gyro, relative ws and direction, true ws and direction, air temp, relative humidity, barometric pressure, short- and long-wave radiation,5m and 1m sea surface temps, Edo depth, Chirp sonar depth, Edo speed, Edo indicator.</li> <li>Check plots of true wind speed and direction to make sure they look ok.</li> <li>Run vector averaging program which produces 60 minute series. The program uses 60 consecutive records and does not check for missing records. I have not carried depths since hourly averages do not seem useful nor Edo speeds since they seem pretty generally useless. Output parameters are: Year day, lat, long, true wind speed and direction, air temp, relative humidity, barometric pressure, short- and long-wave radiation, sea surface temp @ 5m &amp; 1m.</li> </ol> <p>The data quality is generally pretty poor on the Oceanus cruises. OC297 and OC298 have no SOG, COG, or gyro so I could not correct the winds. I almost set the TWS, TWD to 0 but decided to leave them in as RWS, RWD. One could get a semiqualitative feel for the winds. OC301 had gyro but no SOG, COG so I computed them from the GPS position differences. It came out better than I expected. Warn users to be skeptical about the Oceanus data.</p> <p><em>From: Richard E.
