Cdaweb vs omniweb5/5/2023 Two systems of data formats, besides storage in native format, are now in common use: NSSDC's Common Data Format (CDF) and SwRI's Instrument Data File Set (IDFS). Combining data sets is greatly simpli ed when a common storage format is used, so that analysis tools can be applied to data irrespective of their source and content, through a common interface. Space weather applications use data from di erent sources (typically, di erent satellite missions), which have tobe combined in order to study the e ects on systems. These data are continually collected by alarge array of spacecraft and ground based observatories, and made available to the community as on-line data or via mass storage distribution. ![]() Data relevant for space weather applications include: solar activity, solar wind parameters, magnetospheric particle uxes, magnetic eld measurements, magnetic indices, auroral images. Consequently, the availability of the relevant data over computer networks and powerful processing tools are vital for building and maintaining space weather applications, such as: describing the current state of the magnetosphere prediction of "events" that change the environment and may interfere with operations of spacecraft and ground based systems reliable warnings for operators and astronauts. ![]() ![]() DATA PROCESSING, DATA BASES AND TOOLS AVAILABLE: PRESENT AND FUTURE ABSTRACT By their nature, space weather applications rely heavily on access to and processing of data collected by satellite or ground based instruments.
