This data set contains continuous measurements of atmospheric carbon dioxide mole fractions from the NOAA/ESRL observatory at Barrow, Alaska. Data are expressed in hourly, daily and monthly averages in units of micromole/mole for the time period of 1973-2013. Data are archived at the NOAA National Climatic Data Center (NCDC), but are produced and available from NOAA Earth System Research Laboratory (ESRL).
NOAA/ESRL/GMD conducts sustained observations and research related to global distributions, trends, sources and sinks of atmospheric constituents that are capable of forcing change in the climate of the Earth. This research will advance climate projections and provide scientific policy-relevant, decision support information to enhance society's ability to plan and respond.

dataset
CO2 mixing ratios reported in these files were measured by a nondispersive infrared absorption technique. Descriptions of the sampling, measurement, and calibration procedures are given in Peterson et al, 1986, and Zhao and Tans, 2006.
Quasi-continuous CO2 dry air mole fractions from 1980 to 2006 have all been recalculated to bring them into the WMO X2007 Mole Fraction Scale (X07). The data since 2007 were already on the X07 scale. WMO X2007 is based on repeated manometric measurements of the NOAA primary standards (Zhao and Tans, 2006) and comparison of those results to similar measurements made over a period of more than 10 years at Scripps Institution of Oceanography. The difference between the X07 and the previous scales propagated by SIO and NOAA (X83, X87, etc.) is ~0.2 ppm (X07-previous) in the 1980s, decreasing to ~0.1 ppm in the late 1990s, and to 0.0 ppm by 2006. The recalculation of individual measurements was accomplished by first determining the X07 values for the reference gases used to measure the air samples and then using those values with the raw data (NDIR voltages) to recompute mole fractions for each sample.

BRW
Barrow, Alaska Observatory (BRW), established in 1973, is located on the northern most point of the United States. It is about 8 km northeast of the village of Barrow and has a prevailing east-northeast wind off the Beaufort Sea. In addition, the National Weather Service (NWS) maintains a weather observing facility in Barrow. Although the measurements at Barrow are made over open tundra, there are large lagoons and a number of lakes in the vicinity, and the Arctic Ocean is less than 3 km northwest of the site. Because of its proximity to these bodies of water and the fact that the prevailing winds are off the Beaufort Sea, BRW is perhaps best characterized as having an Arctic maritime climate affected by variations of weather and sea ice conditions in the Central Arctic. This facility is manned year round by 2 engineers/scientists to complete routine inspections and maintenance of the instruments. Due to its unique location, dedicated and highly trained staff, and excellent power and communications infrastructure, the Barrow Observatory is host to numerous cooperative research projects from around the world.
