a10pco2.for (File 4)
This file provides underway measurements of pCO2 during R/V Meteor Cruise 22/5. Each line of the file contains a sampling date (month/date/year), latitude, longitude, underway measurements of sea surface temperature, salinity, air pCO2, and water pCO2. The file is sorted by longitude and can be read by using the following FORTRAN 77 code [contained in a10pco2.for (File 4)]:

watrpco2 | Numeric | 7 | 101 | 54 |
The variables are defined as follows:
sect | - | is the WOCE Section number; |
date | - | is the sampling date (day/month/year); |
time | - | is the sampling time (GMT); |
jday | - | is the julian day of the century relative to 1900 with time of the day represented as a fractional day (i.e., noon on 1/1/1900 = 0.5); |
latdcm | - | is the latitude of the sampling (in decimal degrees; negative values indicate the Southern Hemisphere); |
londcm | - | is the longitude of the sampling (in decimal degrees; negative values indicate the Western Hemisphere); |
sst | - | is the sea surface temperature (in °C); |
salt | - | is the sea surface salinity (on the PSS); |
airpre | - | is the atmospheric pressure (in atm); |
airxco2 | - | is the observed mole fraction of pCO2 in air [in ppm (dry air)]; |
airpco2 | - | is the air pCO2 (in µatm); |
waterpco2 | - | is the sea surface water pCO2 (in µatm). |
