Abstract:
The Coupling, Energetics, and Dynamics of Atmospheric Regions (CEDAR) Data Base at NCAR/HAO holds information on theoretical models and source code for several empirical models. Theoretical models include: AMIE: The Assimilative Mapping of Ionopsheric Electrodynamics. Produces output on electric fields and conductances. Contact Arthur Richmond or Barbara Emery. CTIM and CTIP: The Coupled Thermosphere Ionosphere Model and Coupled Thermosphere Ionopshere Plasmasphere model are global models of the themosphere and ionosphere above 80 km. Contact person is Tim Fuller-Rowell. FLIP: The Field Line Interhemispheric Plasma model solves for plasma densities and temperatures along flux tubes. The code is available from Philip Richards. GLOW: A thermospheric airglow model developed by Stan Solomon. TIGCM, TIEGCM, and TIMEGCM: The Thermosphere/Ionosphere General Circulation Model (TIGCM) has been expanded to solve for electrodynamics (TIEGCM) in low and mid-latitudes, and extended to the mesosphere (TIMEGCM). Contact Raymond Roble or Barbara Emery. VSH: The Vector Spherical Harmonic produces thermospheric (110-1500 km) global neutral winds based on TIGCM model runs. Source code is available from Timothy Killeen. Empirical Models include: APEX: a geomagnetic field model. Richmond (1995), Van Zandt , et. al (1972). CHIU: Chiu model electron densities. Chiu (1975) E FIELD: gives quiet-day ionospheric electrostatic potential and E X B drifts at 300 km for magnetic latitudes below 60 degrees during polar minimum conditions. Richmond, et. al (1980). HMR: gives electric potential and fields defined by Rich and Maynard (1989) from patterns described by Heppner and Maynard (1987). HPI: tables of interpolations of the NOAA satellite auroral electron flux, Pederson and Hall conductance, and characteristic energy based on the Hemispheric Power Index (HPI). Fuller-Powell and Evans (1987). HWM: Horizontal Wind Model gives neutral winds. Hedin, et. al (1988), Hedin, et. al (1991) IRI: returns neutral temperatures and ionospheric parameters and ion composition. Bilitza (1986). IZMEM: Electric potentials and fields. Papitashvili, et. al (1994). MAGFLD: geomagnetic field model for 1965-1995. MH: Electric potentials and fields parameterized by HPI and Millstone Hill data. Foster (1987), Foster, et. al (1986). MSIS: returns neutral temperature and composition values. Hedin (1983), Hedin (1987). WEIMER: Electric potentials and fields. Weimer (1996). Several of these models are also available from the National Space Science Data Center (NSSDC) at NASA. See: "http://www.gsfc.nasa.gov/nssdc/nssdc_home.html" Bilitza (1990), Bilitza (1991), Bilitza (1992). The CEDAR Data Base is accessible through the WWW and ftp, but users must have a valid access form, available from the WWW or ftp (see Access and Use constraints) or contact Barbara Emery (emery@hao.ucar.edu). See the WWW site for additonal information on accessing the data and Rules of the Road procedures. http://cedarweb.hao.ucar.edu/catalog/Rules.html
