The NSSDC Coordinated Heliospheric Observations Web, COHOWeb, hourly and daily Solar-Terrestrial Relations Observatory-A, STEREO-B, data were made by using high resolution data from from CDAWeb. The STEREO-A COHO file include data derived from the STEREO-A In-Situ Measurements of Particles and CME Transients, IMPACT, Fluxgate Magnetometer data, Thermal Plasma Moments: Solar Wind Proton and Ion Densities, Speeds, Velocity Vector Flow Angles, and Temperatures from the STEREO-A Plasma and Supra-Thermal Ion Composition, PLASTIC, Instrument, and Energetic Particle Fluxes from the STEREO-A IMPACT Solar Energetic Particle, SEP, Instrument Suite including the Low Energy Telescope, LET, High Energy Telescope, HET, and Suprathermal Ion Telescope, SIT. COHOWeb's magnetic field hourly averages were created at GSFC/SPDF by averaging over the six 10-min averages falling within each hour. Hourly plasma parameter data were obtained from UNH via http://fiji.sr.unh.edu/1dmax_ascii/.

This web site provides a overview description of the data and services provided by the COHOWeb interface and includes spacecraft mission specific notes, the data format specification, and coordinate system descriptions.
Data access and services for hourly and daily merged interplanetary magnetic field, plasma, proton fluxes, and ephemerides data from deep space satellite missions. The services include: 1) Graphical browse and listing, 2) Listing, and plotting with filtering, 3) Distribution functions, medians, averages, standard deviations, 4) Scatter plotting, linear regression fitting, 5) FTP access to hourly data, and 6) FTP access to high resolution data.
The OMNIWeb Plus integrated interface provides access to the many interplanetary magnetic field, plasma, and energetic particle data sets hosted by the Goddard Space Flight Center, GSFC, Space Physics Data Facility, SPDF. OMNIWeb Plus services are available via several underlying interfaces including: OMNIWeb, COHOWeb, FTPBrowser, CDAWeb, HelioWeb, and direct HTTPS access that offering various functionalities.
Paths to magnetic field, plasma, energetic particle, and ephemeris data relevant to heliospheric studies resident at the Goddard Space Flight Center, GSFC, Space Physics Data Facility, SPDF
