Elliott, W P

The report describes the selection processes used by NOAA/GMCC for selecting background hourly average CO{sub 2} data from Mauna Loa Observatory. Selection involved three steps: a preliminary selection based on within hour variability of the CO{sub 2} concentration determined by checking the analog output of the CO{sub 2} analyzed on a strip chart recorder; an hour-to-hour concentration difference that rejects data which change by more than 0.25 ppm from one hour to the next; and a selection based on residuals from a spline fit. Examples are shown for the 1985 data, with emphasis on January and August.
