GLOBALVIEW-CO : Sampling Locations

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

The descriptive information includes

Identification code and location. Note that in some instances the identification code includes additional informatio n (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.
