Hallo Shawn Smith,

we want to submit our continously measured meteorological data 
from Meteor cruise M62/2 (8.Aug.-1.Sep.04) in the western tropical 
Atlantic (principal investigator: Peter Brandt). The 1 minute averages 
of air pressure, air temperature, humidity, zonal and meridional 
windspeed, true windspeed, true wind direction, global radiation and 
UV radiation are post-processed and calibrated.
I attached a file containing the data and a readme file to this mail.
Please feel free to contact me for further information:
vhormann@ifm-geomar.de

Sincerely, Verena Hormann
You can find in the file:
m622.dat,
post-processed and calibrated
1 minute temporal values 
from the DVS-database.

no value / error value: -999.99

Variables [Units]:
 1. date [ ddmmyy ], 
 2. time [ hhmmss ],
 3. julian days [ days since 2004/01/01 ],
 4. latitude [ decimal degrees north ], 
    Device: GPS
 5. longitude [ decimal degrees east ], 
    Device: GPS
 6. SST [ degrees C ], 
    Sea surface temperature was continously measured by a 
    thermosalinograph sampling water from a depth of 1.5 m 
    below the vessel's waterline. The temperature sensor was 
    calibrated against on-station temperature and conductivity 
    values from CTD-profiles.
    Device: Seacat SBE 21
    Manufacturer: SEA-Bird Electronics, Inc.
 7. SSS [ p.s.u. ],
    Sea surface salinity was continously measured by a 
    thermosalinograph sampling water from a depth of 1.5 m 
    below the vessel's waterline. The conductivity sensor was 
    calibrated against on-station conductivity and temperature 
    values from CTD-profiles.
    Device: Seacat SBE 21
    Manufacturer: SEA-Bird Electronics, Inc.
 8. air pressure [ hPa ], 
    Manufacturer: AIR, type DB-1A
    Location of measurements: 10.6 m above sea level
 9. air temperature [ degrees C ], 
    Device: PT 100
    Location of measurements: 28.3 m above sea level
10. humidity [ % ], 
    Relative humidity was measured by two sensors at 28.3 m above sea 
    level, one on port and one on starport side. After calibration of 
    the sensors, the luv sensor is included in the dataset.
    Device: capacitive humidity sensors
    Manufacturer: Rotronic 
11. zonal windspeed [ m/s ],
12. meridional windspeed [ m/s ], 
13. true windspeed [ m/s ], 
    Windspeed was measured by two heated cup anemometers at 40.1 m 
    above sea level on port and starport side. Relative wind was 
    converted to absolute wind using ships heading and speed. The 
    luv sensor data is included in this dataset.
14. true wind direction [ degrees ],
    Wind direction was measured by two vanes at 40.1 m above sea 
    level on port and starport side. Relative wind was converted 
    to absolute wind using ships heading and speed. The luv sensor 
    data is included in this dataset.
15. global radiation [W/m^2],
    measured by a Pyranometer, Typ CM21
    Manufacturer: Kipp & Zonen, Delft, Netherlands
    Location of measurements: 40.1 m above sea level, 
                              mid-ship on starboardside
16. UV radiation [mW/m^2],
    measured by a radiometer build by Meteorologisches Observatorium 
    Potsdam (DWD)
    Location of measurements: 40.1 m above sea level, mid-ship
