Experiment for Coordinated Helioseismic Observations (ECHO)

Project: Experiment for Coordinated Helioseismic Observations (ECHO)
Project URL: http://www.hao.ucar.edu/public/research/mlso/LowL/lowl.html
Data Title: Frequencies and frequency splittings
Data URL: http://www.hao.ucar.edu/public/research/mlso/LowL/data.html
Description: The LOWL is an instrument which measures the properties of the solar oscillations. These oscillations are acoustic waves trapped below the surface of the Sun which set up globally coherent modes of oscillation. Observation of the surface manifestation of these modes allows the inference of the structural and rotational properties of the solar interior. This process is analogous to the seismological study of the earth and is therefore called "helioseismology". The ECHO is the next generation of the LOWL instrument.

Project: Skylab
Project URL: http://www.hao.ucar.edu/public/research/mlso/Skylab/skylab_homepage.html
Data Title: CME's from skylab, images, movies
Data URL: http://download.hao.ucar.edu/skylab
Description: Scientists took advantage of Skylab's ability to collect nearly continuous observations of the sun to study the changing structure of many solar features. Previously, observations had taken place: from the earth, with its limitations on wavelength; during eclipses, which allow the corona to be seen, but only for short periods of time and the outer corona is still very dim; and from space, with short duration observations or unmanned spacecraft, which followed a rigid observing schedule.

Solar Maximum Mission Coronameter/Polarimeter (SMM C/P)

Project: Solar Maximum Mission Coronameter/Polarimeter (SMM C/P)
Project URL: http://www.hao.ucar.edu/public/research/svosa/smm/smmcp_cme.html
Data Title: CME movie, images, synoptic charts, CME catalogues
Data URL:
Description: SMM's payload consisted of eight instruments that provided broad spectral coverage of radiation produced by solar flares. Among SMM's primary science objectives was the study of the dynamics of solar flares and the study of solar magnetic fields associated with the flare phenomenon. HAO provided a white-light coronagraph/polarimeter (C/P) to study the relationship of the corona to the flare process. This instrument obtained coronal images from March through September of 1980 before suffering an electronics failure that rendered it inoperative.

HAO Spectral Diagnostics Package (DIAPER)

Project: HAO Spectral Diagnostics Package (DIAPER)
Project URL: http://download.hao.ucar.edu/archive/diaper
Data Title: HAO Spectral Diagnostics Package
Data URL: http://download.hao.ucar.edu/archive/diaper
Description: HAO Spectral Diagnostics Package consists of three components: (1) a set of atomic models, and IDL procedures for manipulating them, (2) a suite of FORTRAN-77 and IDL programs which can calculate spectra from these models, and (3) sets of IDL procedures for performing integral inversions (emission measure analysis and density/temperature diagnostic work). The SDP can be used for calculations ranging from LTE calculations of photospheric lines, through NLTE calculations of coronal emission lines. It can be used to determine line emissivities for application to studies of emission lines formed in a variety of astrophysical sources. It contains packages for the computation of approximate atomic data and it will also contain interfaces to other atomic databases.

Advanced Stokes Polarimeter

Project: Advanced Stokes Polarimeter
Project URL: http://www.hao.ucar.edu/public/research/spmf/asp.html
Data Title: Stokes profile inversion
Data URL: By request
Description: The Advanced Stokes Polarimeter is an instrument for measuring the polarization of lines in the solar spectrum, thus allowing scientists to infer both the strength and direction of magnetic fields in the solar atmosphere. This instrument represents a major advance in scientific capability for understanding solar magnetic fields and related phenomena. Its angular resolution is roughly a factor of 10 better than its predecessors, and, with its precise polarization calibration and simultaneous wavelength coverage of lines of differing sensitivity to the Zeeman effect, it is now possible to specify the actual strength of the kiloGauss solar magnetic elements within 10-20 Gauss, and their field orientations within a few degrees.

CEDAR database

Project: CEDAR database
Project URL: http://cedarweb.hao.ucar.edu/catalog/cat.toctext.html
Data Title: CEDAR database
Data URL: http://cedarweb.hao.ucar.edu/menu.html

Description: Coupling, Energetics, and Dynamics of Atmospheric Regions (CEDAR) is a program sponsored by the National Science Foundation (NSF) designed to enhance the capability of ground-based instruments to measure the upper atmosphere and to coordinate instrument and model data for the benefit of the scientific community. The CEDAR Database (formerly the Incoherent Scatter Radar Data Base) is a cooperative project between the National Center for Atmospheric Research (NCAR) and several institutions that provide upper atmosphere data and model output for community use. In addition, the Database also contains material useful for analyzing these data: documentation, catalogue information, geophysical indices, summary plots, analysis software, and computer models. The purpose of the Database is to make data from these instruments and models readily accessible for scientific research by the entire scientific community.

Project: TIME-GCM
Project URL: http://www.hao.ucar.edu/public/research/tiso/tgcm/tgcm.html
Data Title: TIMEGCM output
Data URL: By request
Description: The NCAR TGCM's are three-dimensional, time-dependent models of the EARTH's neutral upper atmosphere. The model uses a finite differencing technique to obtain a self-consistent solution for the coupled, nonlinear equations of hydrodynamics, thermodynamics, continuity of the neutral gas and for the coupling between the dynamics and the composition. The output of the TIME-GCM consists of 30 fields on a three-dimensional latitude, longitude, pressure grid. Geographic longitude begins at -180 degrees west and continues around the globe with a 5 degree resolution. Geographic latitude resolution is also 5 degrees, from -87.5 south to +87.5 north. The vertical dimension is in a log pressure scale (ln(p0/p)) from -17.0 at the bottom (approximately 30 km) to 5.0 at the top (varying in altitude up to about 400 km). The vertical resolution is 0.5, for a total of 45 pressures.

Assimilative Mapping of Ionospheric Electrodynamics (AMIE)

Project: Assimilative Mapping of Ionospheric Electrodynamics (AMIE)
Project URL: http://www.hao.ucar.edu/public/research/tiso/amie/AMIE_head.html
Data Title: AMIE
Data URL: http://download.hao.ucar.edu/archive/amie
Description: The Assimilative Mapping of Ionospheric Electrodynamics (AMIE) procedure is an optimally constrained, weighted least-squares fit of electric potential distribution to diverse types of atmospheric observations. Knowledge of these distributions is important in many areas of magnetospheric, ionospheric, and thermospheric physics. Applications of the AMIE procedure have shown the value of describing rapidly changing convection patterns. These data can be of great use in evaluating the spatio-temporal variations of electrodynamic fields needed for simulation models.

Global Scale Wave Model (GSWM)

Project: Global Scale Wave Model (GSWM)
Project URL: http://www.hao.ucar.edu/public/research/tiso/gswm/gswm.html
Data Title: GSWM amplitude and phase of each component of the tide at gridpoints of latitude and altitude
Data URL: http://www.hao.ucar.edu/public/research/tiso/gswm/gswm.html
Description: Atmospheric solar tides are global-scale waves with periods that are harmonics of a 24 hour day. Migrating tidal components propagate westward with the apparent motion of the sun, so their zonal wavenumbers are identical to their frequency (in units of "tide maxima per day"). These components are thermally driven by the periodic absorption of solar radiation throughout the atmosphere, primarily the absorption of UV radiation by stratospheric ozone and of IR by water and water vapor in the troposphere. The Global-Scale Wave Model (GSWM) solves the linearized and extended Navier-Stokes equations for steady-state global temperature and wind perturbations. GSWM may be used to calculate an "unforced" planetary wave response for a specified period and zonal wavenumber, or the thermally-driven response for either a diurnal or semidiurnal atmospheric tide.
