Calibrated data that has been mapped onuniform space-time grid scales with gaps, flags and out-of-range valuesreplaced with appropriate values. Similar to NASA Level 3.
A string defining the output format used whenextracting data values out to a file or screen. The magnitude and the numberof significant figures needed should be carefully considered. The outputformat
string can be in either Fortran or C syntax.
The ring-shaped regions of charged particles surrounding the Earth from 1 to 6 Earth radii into space. The charged particles are trapped in by the Earth's magnetic field. The inner belt is between 1.2
and 4.5 Earth radii and contains high-energy electrons and protons which originate mainly from interactions between cosmic rays and the upper atmosphere. The outer belt, located between 4.5 and 6.0 Earth radii, contains lower-energy charged particles mainly coming from the solar wind.
