Title: Atmospheric Carbon Dioxide Record from Mauna Loa

Abstract

The Mauna Loa atmospheric CO2 measurements constitute the longest continuous record of atmospheric CO2 concentrations available in the world. The Mauna Loa site is considered one of the most favorable locations for measuring undisturbed air because possible local influences of vegetation or human activities on atmospheric CO2 concentrations are minimal and any influences from volcanic vents may be excluded from the records. The methods and equipment used to obtain these measurements have remained essentially unchanged during the 51-year monitoring program.Because of the favorable site location, continuous monitoring, and careful selection and scrutiny of the data, the Mauna Loa record is considered to be a precise record and a reliable indicator of the regional trend in the concentrations of atmospheric CO2 in the middle layers of the troposphere. On the basis of flask samples collected at Mauna Loa, and analyzed by SIO, the annual average of the fitted concentrations of CO2 rose from 315.98 ppmv in 1959 to 385.34 ppmv in 2008. This represents an average annual growth rate of 1.4 ppmv per year in the in situ values at Mauna Loa.

The concentration of atmospheric CO/sub 2/ in the Northern Hemisphere increased by 6.8 ppM from 1959 to 1969, according to a long series of measurements at the Mauna Loa Observatory, Hawaii. In the same period the Southern Hemisphere concentration increased by 6.7 ppM, according to an even longer series of measurements of South Polar air. These increases, when averaged, correspond to 2.34% of the presumed preindustrial CO/sub 2/ concentration of 290 ppM and imply that approximately 49% of the contemporary production ofmore »« less
Atmospheric carbon dioxide at Mauna Loa Observatory 2. Analysis of the NOAA GMCC data, 1974--1985

The first 12 years (1974--1985) of continuous atmospheric CO/sub 2/ measurements from the NOAA GMCC programs at the Mauna Loa Observatory in Hawaii are analyzed. Hourly and daily variations in the concentration of CO/sub 2/ due to local sources and sinks are described, with subsequent selection of data representing background concentrations. A digital filtering technique using the fast Fourier transform and low-pass filters was used to smooth the selected data and to separate the seasonal cycle from the long-term increase in CO/sub 2/. The amplitude of the seasonal cycle was found to be increasing at a rate of 0.05/plus minus/0.02more »« less

Atmospheric CO/sub 2/ measurements made with a nondispersive infrared analyzer during 1974--1985 at Mauna Lao Observatory, Hawaii, are described, with emphasis on the measurement methodology, calibrations, and data accuracy. Monthly mean CO/sub 2/ data, representative of global background conditions, are presented for the period of record. The monthly means were derived from an all-data base of CO/sub 2/ hourly averged archived at the National Oceanic and Atmospheric Administration (NOAA) Geophysical Monitoring for Climatic Change (GMCC) facility in Boulder, Colorado; at the Carbon Dioxide Information Analysis Center (CDIAC) in Oak Ridge, Tennessee; and in the microfiche version of this paper.

Atmospheric Carbon Dioxide Record from Flask Measurements at Lampedusa Island (May 1992- December 2000)

Lampedusa Station rests on a rocky seashore on the eastern tip of Lampedusa Island, located south of Sicily in the central Mediterranean Sea. Air samples at Lampedusa Station are collected each Friday in two pairs of 2-L glass flasks. Flasks are evacuated and then pressurized to 280-300 kPa with ambient air at the sampling site. Determinations of CO2 are made by using a Siemens Ultramat 5E nondispersive infrared gas analyzer. Water vapor is removed during the sampling process by means of a chemical trap (Magnesium Perchlorate). During the measurement, residual water vapor is removed by means of a cold trapmore »« less
Atmospheric Carbon Dioxide Record from In Situ Measurements at Mt. Cimone (1979-1997)

Dataset Colombo, T. ; Santaguida, R.

Continuous atmospheric CO2 measurements have been carried out at Mt. Cimone since 1979. Since December 1988, air samples have also been collected approximately once per week in a pair of 2-L, electropolished, stainless steel cylindrical flasks. From 1979 until December 1988, a Hartmann and Braun URAS-2T NDIR gas analyzer was used for CO2 determinations. Currently, CO2 determinations are made through the use of a Siemens Ultramat-5E NDIR gas analyzer. Water vapor is eliminated by passing the air through a U-tube placed in an alcohol bath at -600°C. Calibration of the Ultramat-5E is accomplished by using two CO2-in-air working standard gases.more »« less
