They are not projections, estimates or averages that use advanced mathematics to generate a daily number. They are precise measurements of the air made at one location in the Earth's atmosphere. Maybe you are wondering why CO2 Earth features daily readings from the Mauna Loa Observatory (MLO) alone and not a seasonally adjusted estimate? If you are, there are many reasons.įirst, CO2 readings from Mauna Loa are direct observations of the Earth system. Why does CO2 Earth focus on Mauna Loa CO2 readings? year-over-year increases in carbon dioxide-increases that have continued and accelerated since Keeling's discovery and which scientists attribute primarily to emissions caused by human activities (roughly 90% fossil fuel combustion and most of the remainder due to land use changes).large difference in seasonable fluctuations betwen the South Pole (least fluctuation) to near the North Pole (highest fluctuation) which shows that seasonal fluctuations are driven mainly by vegetation cycles in the Northern Hemisphere where most land is located.

seasonal fluctuations of CO2 levels in well-mixed background air that is free of local influence such as plant respiration and industry.NOAA's Daily Global CO2 table shows us atmospheric CO2 phenomena that Charles David Keeling discovered with the high-precesion CO2 measuring instruments and programs he created in the 1950s.

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.
