 Parameter   Description                                   Units

 yrday       day of year 1992 (GMT)                        decimal days
 lat         latitude, ship's position at the time of      decimal degrees
               pCO2 measurement (- denotes south)
 lon         longitude, ship's position at the time of     decimal degrees
               pCO2 measurement (- denotes west)
 temp        sea surface temperature measured underway     degrees Celsius
               via the ship's thermo-salinometer
 sal         sea surface salinity measured underway        parts per thousand
               via the ship's thermo-salinometer
 pCO2_air    partial pressure of CO2 in sea surface        microatmospheres
               air, measured at ship's bow while
               underway (corrected to 100% humidity)
 pCO2_sea    partial pressure of CO2 in surface            microatmospheres
               seawater, pumped at ship's bow while
               underway (corrected to 100% humidity)
