NOAA | Curve Fitting Methods Applied to Time Series in NOAA/ESRL/GMD NOAA | Estimated CO2 Trend (seasonally adjusted) daily values NOAA states that lines in the graphic "are a very good estimate of the global average levels of CO 2." Source Graphic: NOAA Global CO2 Trend webpage Recent values are estimates, not current observations. NOAA's Daily Global CO2 chart averages seasonally-adjusted data from four core observatories at different latitudes from the South Pole to Alaska. The Scripps graph shows hourly CO 2 averages with small grey dots, and daily averages with larger black dots. ![]() Scripps reports daily averages based on Mauna Loa local time.
