They utilize numerous types of platforms, including ground-based stations, towers, ships, aircraft, and balloons to accomplish their mission. HATS measures chlorofluorocarbons (CFCs) at measurement sites spanning the globe. CFCs are non-toxic, non-flammable chemicals that contain carbon, chlorine, and fluorine atoms. CFCs were used as solvents, refrigerants, and aerosol sprays. While inert in the troposphere, they decompose in the stratosphere to release chlorine for destructive reactions with ozone. This process eventually led to the creation of the "Ozone Hole" over the Antarctic. Monitoring the amounts of CFCs and other trace gases is important, both for tracking the growth and recovery of the Ozone Hole, and because many upward trending trace gases are potent and durable greenhouse gases. Original flask sampling electron capture gas chromatograph ("Pre-Otto") : Air samples collected in flasks at five remote sites, including Barrow, AK (BRW), Mauna Loa, HI (MLO), American Samoa (SMO), South Pole (SPO), Antarctica, and Niwot Ridge, CO (NWR), were analyzed using the HATS group's original electron capture gas chromatograph (GC-ECD) system beginning in 1977. Two additional sites at Alert, Nunavut, Canada (ALT), and Cape Grim, Tasmania (CGO) were added prior to the original Pre-Otto system's retirement in 1995, when it was replaced by a newer, automated system called "Otto". This program was originally set up under the Geophysical Monitoring for Climatic Change (GMCC) division of NOAA's Air Resources Laboratory. Air was collected weekly at these sites in stainless-steel flasks and analyzed for nitrous oxide (N2O), and the chlorofluorocarbons CFC-11 (CCl3F) and CFC-12 (CCl2F2) in the Boulder labs in Colorado. Through the Big Earth Data Initiative (BEDI), ESRL/GMD has taken their data collection and converted files into NetCDF-4, a self-describing format. The general mission of the Halocarbons and other Atmospheric Trace Species group is to quantify the distributions and magnitudes of sources and sinks for atmospheric nitrous oxide (N2O) and halogen containing compounds. completed David Nance DOC/NOAA/ESRL/GMD > Global Monitoring Division, Earth System Research Laboratory, NOAA, U.S. Department of Commerce CIRES Associate Scientist (303) 497-7002 david.nance@noaa.gov collaborator NOAA National Centers for Environmental Information Customer Engagement Branch 1-828-271-4800 1-828-271-4876 151 Patton Avenue Veach-Baley Federal Building, Room 468 Asheville NC 28801-5001 USA ncei.orders@noaa.gov https://www.ncei.noaa.gov HTTPS Web Browser NOAA National Centers for Environmental Information (NCEI) NCEI home page with information, data access and contact information. information 8:00 - 6:00 Eastern pointOfContact notPlanned https://www.ncei.noaa.gov/pub/data/metadata/images/C01553.jpg Old Flask Gas Chromatograph Instrument JPEG Earth Science > Atmosphere > Atmospheric Chemistry > Nitrogen Compounds > Nitrous Oxide Earth Science > Atmosphere > Atmospheric Chemistry > Halocarbons And Halogens > Chlorofluorocarbons theme Global Change Master Directory (GCMD) Science Keywords 2018 revision Version 8.6 Global Change Data Center, Science and Exploration Directorate, Goddard Space Flight Center (GSFC) National Aeronautics and Space Administration (NASA) https://earthdata.nasa.gov/about/gcmd/global-change-master-directory-gcmd-keywords HTTPS Web Browser Global Change Master Directory (GCMD) Keywords The information provided on this page seeks to define how the GCMD Keywords are structured, used and accessed.

A combination of a commercial electronic integrator and manual assessments from hard copy chart traces was used to evaluate chromatographic peak responses. Peak response measures were manually entered into electronic data files for a further reduction in atmospheric mixing ratios. From this point, a series of mostly 1980s and 1990s vintage workstation/desktop scale computers were used to process and reprocess the peak response measures into mixing ratios using a collection of custom developed FORTRAN routines. 1 -180.0 180.0 -90.0 90.0 ground condition 1977-01-15 1995-12-15 1 NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact NCEI Contact Information Information for contacts at NCEI. information distributor In most cases, electronic downloads of the data are free.

Data reduction was conducted on a desktop computer. Each sample injection was performed manually, and the resulting chromatograms were analyzed by a combination of a commercial electronic integrator and manual techniques. Groupings of air sample injections were interspersed with groupings of reference gas injections, and sample mixing ratios were determined by comparing these responses within the framework of an assumed linear response function through a single reference point and zero. Normalized responses with ancillary information were then manually entered into electronic data files for further processing by FORTRAN coded computer algorithms. Corrections for sample humidity, co-eluting peak response biases (e.g. CO2), and reassessments of the reference gas value were applied downstream in this manner. Quality control measures were used along the entire chain.
