Measuring the Upper layer Temperature of the Polar Oceans

Buoy Parameters

Description of UpTempO Data Variables
Each UpTempO data file has in its header an explicit list of variables identifying the columns of the data set. Below is a complete list of variable names you may encounter.

yearThe year of the data record
monthThe month of the data record
dayThe day of the month of the data record
hourThe hour of the data record (GMT). Ranges from 0 to 23.
Latitude (N)The latitude of the data record
Longitude (E)The longitude of the data record
Ocean Pressure (dB) at Sensor #n (Nominal Depth = xx m)Ocean pressure reported at the stated Nomimal Depth. There are generally one to three ocean pressure sensors.
Temperature at nominal depth xx.x (m)The Celsius temperature at the stated nominal depth.
Estimated Depth at nominal depth xx.x (m)Some buoys report an estimated depth for each thermistor based on the ocean pressure values and a cable model
Sea Level Pressure (mBar)Sea Level Pressure in mBar
Battery Voltage (V)Battery Voltage
Submergence PercentPercent of the time over the previous hour that the buoy was submerged.
Pressure from CTD sensor (db)Pressure at a seabird CTD (conductivity, temperature, depth) sensor.
Salinity from CTD or CT Sensor(psu)Salinity in standard units at a seabird CT or CTD sensor
Temperature from CTD or CT Sensor(Celsius)Temperature in Celsius at a seabird CT or CTD sensor
Wind DirectionDirection the wind is coming from, with 0 degrees = North, and 90 degrees = East
Wind Speed (m/s)Magnitude of the wind
Calculated Depth at nominal depth xx.x (m)More accurate depths for the thermistors, calculated based on ocean pressure values.
Open Water or Ice (1=ice, 2=open water)Indicates whether the buoy is in/near ice or in water.
First wet thermistorIndicates the upper most thermistor that is in water, where 0=the upper most thermistor, 1=the second thermistor, etc. This quantity is intended to provide guidance on how to use thermistor data when some thermistors have been pulled up into an ice ridge.
