Map of Sampling Locations

The following list provides general information on sampling locations for measurement records used to derive GLOBALVIEW-CO2C13. A summary of this list is available as a text file (gv_table.co2c13).

The descriptive information includes

  • Identification code and location. Note that in some instances the identification code includes additional information (see File Names).
  • Organization collecting the air sample or making the measurements.
  • Sampling strategy and platform.
  • Contributing laboratory and average sample frequency of available data. The average is based on the most recent 3 years of available data.
  • Position of the sampling site where latitude is in degrees (000 is at the equator, north of the equator is positive (+), and south of the equator negative (-)), longitude is in degrees (east of Meridian of Greenwich is positive (+), and west of Meridian of Greenwich is negative (-)), and altitude is in meters above sea level (masl).
  • Time period of available measurements.
