The GASP program began in 1972 with a feasibility study of the concept of using commercial airliners in routine service to obtain atmospheric data. While GASP was operational, from March 1975 to June 1979, NASA obtained data with instruments placed aboard a United Airlines B-747, two Pan American Airways B-747s, a Quantas Airways B-747, and the NASA CV-990 research aircraft. There is some data between 1972 and the official start of GASP in 1975. There is also some data between 1979, the year the program officially ended, and 1983. The objectives of GASP were to provide baseline data of selected atmospheric constituents in the upper troposphere and lower stratosphere and to document and analyze these data to 1) prove a better understanding of the dynamics of the atmosphere in the region where commercial aircraft flew, and 2) provide initial value boundary conditions for atmospheric models being used to assess potential adverse effects from aircraft exhaust emissions on the natural atmosphere. For each GASP flight, data acquisition began on ascent through the 6 KM altitude flight level, and terminated on descent through 6 KM. A complete GASP sampling cycle was 60 minutes, divided into 12 five minute sampling segments. During alternate segments (at 10 minute intervals), air sample data was recorded for all instruments. During the intervening segments, the system was on one of six different calibration cycles to allow for in-flight checks on instrument operation (if required). Whenever any calibration cycle was not needed for a given instrument, that instrument acquired air sample data during the segment. For normal GASP sampling, a 16 second recording was made at the end of each five minute sampling segment. The parameters that make up this digital data are beginning and ending times of the flight (GMT), ambient ozone, cabin ozone, water vapor, clouds, carbon monoxide, and filter samples of sulfate, nitrates, chlorides, and fluorides. Also included are tropopause pressure fields and other meteorological data from National Meteorological Center analyses. The National Meteorological Center is now the National Centers for Environmental Prediction (NCEP). To make a wide range of climatic data available to researchers and the public. completed DOC/NOAA/NESDIS/NCEI > National Centers for Environmental Information, NESDIS, NOAA, U.S. Department of Commerce 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 asNeeded Earth Science > Atmosphere > Aerosols > Nitrate Particles Earth Science > Atmosphere > Aerosols > Sulfate Particles Earth Science > Atmosphere > Aerosols > Particulates Earth Science > Atmosphere > Air Quality > Tropospheric Ozone Earth Science > Atmosphere > Air Quality > Carbon Monoxide Earth Science > Atmosphere > Air Quality > Emissions Earth Science > Atmosphere > Atmospheric Chemistry/Carbon And Hydrocarbon Compounds > Carbon Monoxide Earth Science > Atmosphere > Atmospheric Chemistry/Halons And Halogens > Hydrogen Chloride Earth Science > Atmosphere > Atmospheric Chemistry/Halons And Halogens > Hydrogen Fluoride Earth Science > Atmosphere > Atmospheric Chemistry/Oxygen Compounds > Ozone Earth Science > Atmosphere > Clouds > Cloud Properties > Cloud Frequency Earth Science > Atmosphere > Clouds > Cloud Properties > Cloud Base Height Earth Science > Atmosphere > Clouds > Cloud Properties > Cloud Base Height Earth Science > Atmosphere > Clouds > Cloud Condensation Nuclei Earth Science > Atmosphere > Clouds > Cloud Properties > Cloud Height Earth Science > Atmosphere > Clouds > Cloud Properties > Cloud Vertical Distribution Earth Science > Atmosphere > Clouds > Cloud Microphysics > Cloud Droplet Concentration/Size Earth Science > Atmosphere > Altitude > Geopotential Height Earth Science > Atmosphere > Altitude > Barometric Altitude Earth Science > Atmosphere > Altitude > Tropopause Earth Science > Atmosphere > Atmospheric Pressure > Atmospheric Pressure Measurements Earth Science > Atmosphere > Atmospheric Temperature > Surface Temperature > Air Temperature Earth Science > Atmosphere > Atmospheric Temperature > Upper Air Temperature Earth Science > Atmosphere > Atmospheric Water Vapor > Water Vapor Profiles Earth Science > Atmosphere > Atmospheric Water Vapor > Water Vapor Earth Science > Atmosphere > Atmospheric Water Vapor > Water Vapor Indicators > Dew Point Temperature Earth Science > Atmosphere > Atmospheric Winds > Upper Level Winds Earth Science > Atmosphere > Atmospheric Winds > Wind Profiles Earth Science > Atmosphere > Atmospheric Winds > Upper Level Winds > Flight Level Winds Earth Science > Atmosphere > Clouds 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.
