This section has been superseded by the treatment of time series as a type of discrete sampling geometry in Chapter 9.
To represent data at scattered points it is convenient to use a variable with one dimension to represent the measurement locations. Auxiliary coordinate variables are used to associate a single spatial dimension with multiple independent coordinates.
Example 5.4. Timeseries of station data
dimensions: station = 10 ; // measurement locations pressure = 11 ; // pressure levels time = UNLIMITED ; variables: float humidity(time,pressure,station) ; humidity:long_name = "specific humidity" ; humidity:coordinates = "lat lon" ; double time(time) ; time:long_name = "time of measurement" ; time:units = "days since 1970-01-01 00:00:00" ; float lon(station) ; lon:long_name = "station longitude"; lon:units = "degrees_east"; float lat(station) ; lat:long_name = "station latitude" ; lat:units = "degrees_north" ; float pressure(pressure) ; pressure:long_name = "pressure" ; pressure:units = "hPa" ;
