The DMSP program maintains a constellation of sun-synchronous, near-polar orbiting satellites. The orbital period is 101 minutes and inclination is 99 degrees. The atmospheric and oceanographic sensors record radiances at visible, infrared and microwave wavelengths. The solar geophysical sensors measure ionospheric plasma fluxes, densities, temperatures and velocities. DMSP visible and infrared imagery of clouds covers a 3,000 km swath, thus each satellite provides global coverage of both day night time conditions each day. The field view of the microwave imagers and sounders is only 1,500 km thus approximately 3 days data are required for one instrument to provide global coverage at equatorial latitudes. The solar geophysical instruments make in-situ measurements of ionospheric parameters, some of which vary very rapidly. The NOAA National Centers for Environmental Information (formerly National Geophysical Data Center) receive the complete DMSP data stream from the Air Force Weather Agency (AFWA), Offutt Air Force Base, Omaha, Nebraska. Data are currently transmitted in near realtime from AFWA directly to the archive via a designated T1 line. Archive processing prepares orbital data sets of calibrated, quality assessed data organized as a time-series, restores data lost during transmission,and accurately computes satellite positions. NCEI maintains an archive of all data recorded on DMSP satellites as relayed to The NOAA National Centers for Environmental Information (formerly National Geophysical Data Center) by the Air Force Weather Agency. Data from March 1992 to March 1994, are considered to be experimental. After March 1994, the system was fully operational. NCEI archives contain data that are post process reconstructed, positioned and geolocated using the same software. purpose: Earth and Near-Earth Environment Research status: (MD_ProgressCode) underDevelopment pointOfContact: (CI_ResponsibleParty) individualName: DMSP Data Manager organisationName: DOC/NOAA/NESDIS/NCEI > National Centers for Environmental Information, NESDIS, NOAA, U.S. Department of Commerce contactInfo: (CI_Contact) phone: (CI_Telephone) voice: 303.497.3053 facsimile: (303) 497-6513 address: (CI_Address) deliveryPoint: E/GC2 325 Broadway city: Boulder administrativeArea: CO postalCode: 80305 country: USA electronicMailAddress: ngdc.dmsp@noaa.gov hoursOfService: 7:30 - 4:30 Mountain contactInstructions: Contact Data Center role: (CI_RoleCode) pointOfContact resourceMaintenance: (MD_MaintenanceInformation) maintenanceAndUpdateFrequency: (MD_MaintenanceFrequencyCode) daily descriptiveKeywords: (MD_Keywords) keyword: Earth Science > Atmosphere > Atmospheric Temperature keyword: Earth Science > Atmosphere > Atmospheric Water Vapor > Water Vapor keyword: Earth Science > Atmosphere > Clouds keyword: Earth Science > Atmosphere > Precipitation keyword: Earth Science > Biosphere > Ecological Dynamics > Fire Occurrence keyword: Earth Science > Hydrosphere > Snow/Ice keyword: Earth Science > Hydrosphere > Surface Water keyword: Earth Science > Hydrosphere > Surface Water > Lakes keyword: Earth Science > Hydrosphere > Surface Water > Rivers/Streams keyword: Earth Science > Oceans > Ocean Winds keyword: Earth Science > Oceans > Sea Ice keyword: Earth Science > Spectral/Engineering > Infrared Wavelengths keyword: Earth Science > Spectral/Engineering > Microwave keyword: Earth Science > Spectral/Engineering > Microwave > Brightness Temperature keyword: Earth Science > Spectral/Engineering > Visible Wavelengths keyword: Earth Science > Sun-earth Interactions > Ionosphere/Magnetosphere Particles keyword: Earth Science > Sun-earth Interactions > Ionosphere/Magnetosphere Particles > Electron Flux keyword: Earth Science > Sun-earth Interactions > Ionosphere/Magnetosphere Particles > Particle Density keyword: Earth Science > Sun-earth Interactions > Ionosphere/Magnetosphere Particles > Particle Speed keyword: Earth Science > Sun-earth Interactions > Ionosphere/Magnetosphere Particles > Particle Temperature keyword: Earth Science > Sun-earth Interactions > Ionosphere/Magnetosphere Particles > Proton Flux type: (MD_KeywordTypeCode) theme thesaurusName: (CI_Citation) title: NASA/GCMD Earth Science Keywords date: (unknown) descriptiveKeywords: (MD_Keywords) keyword: DMSP keyword: Global Change keyword: Meteorological Satellites keyword: Polar Orbiters keyword: Satellite Meteorology type: (MD_KeywordTypeCode) theme thesaurusName: (CI_Citation) title: Uncontrolled Keywords date: (unknown) descriptiveKeywords: (MD_Keywords) keyword: ICSU-WDS > International Council for Science - World Data System type: (MD_KeywordTypeCode) project thesaurusName: (CI_Citation) title: Global Change Master Directory (GCMD) Project Keywords date: (CI_Date) date: 2020-01-09 dateType: (CI_DateTypeCode) publication edition: 9.1 citedResponsibleParty: (CI_ResponsibleParty) organisationName: NASA Goddard Space Flight Center, Earth Science Data and Information System contactInfo: (CI_Contact) onlineResource: (CI_OnlineResource) linkage: https://www.earthdata.nasa.gov/learn/find-data/idn/gcmd-keywords name: Global Change Master Directory (GCMD) Keywords description: The information provided on this page seeks to define how the GCMD Keywords are structured, used and accessed.

The OLS instrument consists of two telescopes and a photomultiplier tube (PMT). The detectors sweep back and forth in a "whiskbroom" fashion (a "flying spot design" is employed - a subset of whiskbroom scanners). The continuous analog signal is sampled at a constant rate so the Earth-located centers of each pixel are roughly equidistant, i.e., 0.5 km apart, 7,325 pixels are digitized in the cross-track direction. type: Detectors description: Collection Type: Whiskbroom, Collection Description: Unknown instrument: (MI_Instrument) identifier: (MD_Identifier) code: SSM/I (Special Sensor Microwave Imager). The SSM/I is a seven-channel, four-frequency, linearly-polarized, passive microwave radiometer (a total-power instrument configuration) which measures atmospheric, ocean, and terrain microwave brightness temperatures (similar to NIMBUS-7 SMMR) which are converted into environmental parameters such as: sea surface winds, rain rates, cloud water, precipitation, soil moisture, ice edge, and ice age. SMM/I data is used to obtain synoptic maps of critical atmospheric, oceanographic and selected land parameters on a global scale. The footprint of SSM/I data is a 1400 km swath (conical scan). type: Microwave Radiometer description: Collection Type: Unknown, Collection Description: Unknown instrument: (MI_Instrument) identifier: (MD_Identifier) code: SSM/T (Special Sensor Microwave Temperature Sounder). The SSM/T is a seven channel passive microwave sounder consisting of a rotating 7 step antenna reflector (rotating once every 32 seconds), a Dicke-switched seven channel radiometer, a digitizer, and signal processor. It measures the Earth's surface and atmospheric emission in the 50 to 60 GHz oxygen band. The SMM/T is a cross-track nadir scanning radiometer having a FOV of 14.4A?. At nominal altitude (833 km) the subtrack spatial resolution is an approximate circle of 174 km diameter at nadir elongating to an ellipse of 305 x 313 km at the extreme viewing angles toward the limb. There are seven total cross-track scan positions separated by 12A? with a maximum cross-track scan angle of 36A?. Swath width = 1500 km (data coverage gap between successive orbits). The SSM/T is a step and stare type sensor which dwells on each of the seven scene stations, then observes a cold (3 K) reference, followed by a warm (300 K) reference. type: Sensor description: Collection Type: Unknown, Collection Description: Unknown instrument: (MI_Instrument) identifier: (MD_Identifier) code: SSM/T2 (Special Sensor Microwave Water Vapor Profiler-2). The instrument is a cross-track scanning, five channel, passive total power microwave radiometer system which consists of a single, self-contained module with a step-scan motion in the cross-track direction of A? 40.5A?. The SSM/T2 scan mechanism is synchronized with the SSM/T so that the beam cell patterns of the two sensors coincide. The observation rate is 7.5 scans/minute. There are 28 observations (beam positions) per scan for each of the five channels, with each observation having a spatial resolution of about 48 km. All five channels have coincident centers. The swath width is about 1500 km. type: Water Vapor Profiler description: Collection Type: Unknown, Collection Description: Unknown instrument: (MI_Instrument) identifier: (MD_Identifier) code: SSJ/4 (Precipitation Electron/Proton Spectrometer) Objective: Measurement of transfer energy, mass, and momentum of charged particles through the magnetosphere-ionosphere in the Earth's magnetic field. The instrument looks toward the satellite zenith. - The SSJ/4 sensor consists of four electrostatic analyzers that record the flux of precipitating ions or electrons at 20 fixed energy channels between 30 eV and 30 keV. The curved plate detectors allow precipitating electrons and ions to enter through an aperture of about 20 x 10 (FWHM). Electrons and ions of the selected energy are deflected toward the target by an imposed electric field applied across the two plates. The two low energy detectors consist of 10 channels centered at 34, 49, 71, 101, 150, 218, 320, 460, 670, and 960 eV. The high energy detector measures particles in 10 channels centered at 1.0, 1.4, 2.1, 3.0, 4.4, 6.5, 9.5, 14.0, 20.5 and 29.5 KeV. Each detector integrates each channel for 0.09 s from high energy channel to low. A complete cycle is sampled each second. The primary sources of the particles precipitating into the upper atmosphere are the northern and southern auroral zones. type: Spectrometer description: Collection Type: Unknown, Collection Description: Unknown instrument: (MI_Instrument) identifier: (MD_Identifier) code: SSI/ES (Special Sensor Ionospheric Plasma Drift/Scintillation Monitor) Objective: Measurement of the ambient electron density and temperatures, the ambient ion density, and the average ion temperature and molecular weight at the DMSP orbital altitude. The instrument consists of an electron sensor (Langmuir probe) and an ion sensor mounted on a 2.5 meter boom. The ion sensor is a planar aperture, planar collector sensor oriented to face the spacecraft velocity vector at all times. In addition to the Langmuir probe and planar collector which make up the SSI/E, the SSI/ES has a plasma drift meter and a scintillation meter. type: Plasma Drift Meter and a Scintillation Meter description: Collection Type: Unknown, Collection Description: Unknown instrument: (MI_Instrument) identifier: (MD_Identifier) code: SSM (Special Sensor Magnetometer), a triaxial fluxgate magnetometer. The SSM measures geomagnetic fluctuations associated with solar geophysical phenomena (i.e., ionospheric currents flowing at high latitudes). In combination with the SSI/ES and the SSJ/4, the SSM provides heating and electron density profiles in the high-latitude ionosphere. SSM takes and reports 12 readings/s for the Y and Z axes. Only 10 readings of the 12 readings per second are reported for the X axis due to telemetry limitations. The SSM's axes are aligned with the spacecraft's axes where X is downward and aligned to local vertical within 0.01 degree, Y is parallel to the velocity vector for spacecraft with ascending node in the afternoon/evening sector, and Z is away from the solar panel and anti-parallel to the orbit normal vector.) The measurement range is A?65535 nT for each axis, with a one-bit resolution of 2 nT. Note: The magnetic field has three sources: 1) the magnetic field from the solid Earth, 2) the magnetic field from electrical currents flowing in the ionosphere and magnetosphere, and 3) the magnetic field from the spacecraft. Measurement of source 2 is the principal objective of the SSM, the measurement of source 1 is a secondary objective, and measurement of source 3 is a nuisance which is eliminated from the data as much as possible during data processing type: Magnetometer description: Collection Type: Unknown, Collection Description: Unknown operation: (MI_Operation) identifier: (missing) status: (MD_ProgressCode) completed parentOperation: (inapplicable) platform: (MI_Platform) identifier: (MD_Identifier) code: Defense Meteorological Satellite Program F12 (DMSP 5D-2/F12) description: (missing) instrument: (missing) platform: (MI_Platform) identifier: (MD_Identifier) code: Defense Meteorological Satellite Program F13 (DMSP 5D-2/F13) description: (missing) instrument: (missing) platform: (MI_Platform) identifier: (MD_Identifier) code: Defense Meteorological Satellite Program F14 (DMSP 5D-2/F14) description: (missing) instrument: (missing) platform: (MI_Platform) identifier: (MD_Identifier) code: Defense Meteorological Satellite Program F15 (DMSP 5D-2/F15) description: (missing) instrument: (missing) platform: (MI_Platform) identifier: (MD_Identifier) code: Defense Meteorological Satellite Program F16 (DMSP 5D-2/F16) description: (missing) instrument: (missing) platform: (MI_Platform) identifier: (MD_Identifier) code: Defense Meteorological Satellite Program F17 (DMSP 5D-2/F17) description: (missing) instrument: (missing) platform: (MI_Platform) identifier: (MD_Identifier) code: Defense Meteorological Satellite Program F18 (DMSP 5D-2/F18) description: (missing) instrument: (missing) | |
