3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Satellite Electromagnetic Observation Electromagnetic Observation Observation Onboard Satellite
Use instruments mounted on satellites to measure the electromagnetic field and its changes in the ionosphere, as well as ionospheric related parameters, such as plasma in-situ, high
Observation of particles, ionospheric structure, etc.
3.2
Satellite Electromagnetic Observation Item Electromagnetic Observation Observation Item Onboard Satellite Lite
The method category of satellite electromagnetic observation.
3.3
Measured item component compoint of observatory item
All observations belonging to the same observation method category.
[DB/T 3-2011, definition 3.2]
3.4
Plasma Plasma
An ionized gas, a material form with free electrons and charged ions as the main components, is often regarded as the fourth state of matter, with
It has high electrical conductivity, strong coupling with electromagnetic field, and overall electrical neutrality.
DB/T 67-2017
3.5
Energetic particle energetic particle
Particles with energies ranging from thousands of electron volts to hundreds of trillion electron volts, mainly including protons and electrons, in addition to atomic nuclei and other
Other subatomic particles and so on.
3.6
Ionosphere ionosphere
The area in the upper atmosphere partially ionized by solar radiation can significantly affect the transmission of radio waves, and the height ranges from about 60 km to
Between 1000 km, it can usually be divided into D, E, and F zones.
[GB/T 30114.2-2014, definition 5.1]
3.7
Ionospheric scintillation ionosphere scintillation
When radio waves traverse the ionosphere, short-period irregular changes in signal amplitude and phase caused by the irregular structure of the ionosphere.
4 Classification principles and methods
4.1 Classification principles
4.1.1 It should be able to distinguish satellite electromagnetic observations from ground electromagnetic observations, and satellite observations of other physical or chemical quantities.
4.1.2 According to the observation category, observation object, observation component or sub-item of the satellite electromagnetic observation, it is divided in order.
4.2 Classification method
This standard uses the line classification method given in GB/T 7027-2002 to divide the seismic satellite electromagnetic observation items into four levels.
---The first level is seismic satellite electromagnetic observation, which is different from ground electromagnetic observation in the seismic industry and satellite observation in other disciplines.
---The second level is the observation category, which is used to characterize the seismic satellite electromagnetic observations for obtaining ionospheric electromagnetic information.
Observations in the same category include observations of electric fields, magnetic fields, plasma in situ, high-energy particles, and ionospheric structure.
---The third level is the object of observation, based on the physical quantity that characterizes the electromagnetic information of the ionosphere, and is used to distinguish different types of
Same as the observation object.
---The fourth level is the measurement item component or sub-item, used to distinguish different components or sub-items of the same observation object.
5 Coding method
5.1 The arrangement of the classification and code tables of this standard adopts the example method of GB/T.20001.3-2001 Table A.1.
6 Classification and code table
See Table 1 for the classification and code list of seismic satellite electromagnetic observation items.
