Data records consist of UTC time, date, and processed ozone mixing ratio (parts per billion by volume). Data is collected from global locations and is provided in 1 hour averages. The data were produced and are available from the NOAA Earth System Research Laboratory (ESRL) Global Monitoring Laboratory, and the data are archived by the NOAA National Centers for Environmental Information (NCEI). Version 2 is a re-processing of the version 1 dataset with corrections for calibration and quality assurance errors. The re-processing was done based on historical calibration and quality control documentation. This dataset is available to the public for a wide variety of uses including scientific research and analysis. completed historicalArchive NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact HTTPS NCEI Contact Information Information for contacts at NCEI. information pointOfContact asNeeded https://www.ncei.noaa.gov/access/metadata/landing-page/bin/gfx?id=gov.noaa.nodc:0312023 Preview graphic PNG 0312023 NCEI ACCESSION NUMBER 2025-12-29 publication Ozone theme NODC DATA TYPES THESAURUS spectrophotometer instrument NODC INSTRUMENT TYPES THESAURUS in situ meteorological theme NODC OBSERVATION TYPES THESAURUS weather stations platform NODC PLATFORM NAMES THESAURUS NOAA Global Monitoring Laboratory dataCentre NODC COLLECTING INSTITUTION NAMES THESAURUS NOAA Global Monitoring Laboratory dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS meteorology theme WMO_CategoryCode 2012-09-15 publication DOC/NOAA/OAR/ESRL/GMD > Global Monitoring Division, Earth System Research Laboratory, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2026 revision 23 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) Greenbelt MD https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords HTTPS GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.

NOAA National Centers for Environmental Information custodian spectrophotometer spectrophotometer spectrophotometer, optical spectrometer, spectrograph or spectroscope An optical spectrometer (spectrophotometer, spectrograph or spectroscope) is an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum, typically used in spectroscopic analysis to identify materials. Butler, L. R. P.; Laqua, K. (1995). "Nomenclature, symbols, units and their usage in spectrochemical analysis-IX. Instrumentation for the spectral dispersion and isolation of optical radiation (IUPAC Recommendations 1995)". Pure Appl. Chem. IUPAC. 67 (10): 1725–1744. doi:10.1351/pac199567101725. A spectrometer is the general term for describing a combination of spectral apparatus with one or more detectors to measure the intensity of one or more spectral bands." weather stations Weather Stations are facilities or locations where meteorological data are gathered, recorded, and released. Such stations are of the first order when they make observations of all the important elements either hourly or by self-registering instruments; of the second order when only important observations are taken; of the third order when simpler work is done, as to record rainfall and maximum and minimum temperatures.
