OSCAR

Each instrument is assigned with a 5-step rating, evaluated as a blend of several elements.  For this particular Variable, the rating is driven by:

• the observing technique (radio occultation, e.m. oscillations, UV/EUV spectrometry);
• the observed volume (magnetosphere or Earth’s limb or platform environment)
• whether the measurement is performed by more satellites flown in cluster.

RATING CRITERIA:

1

• Radio occultation receiver flown in a dedicated constellation
• Radio occultation receiver flown on single satellite

2

• Magnetic and electric oscillator flown through the magnetosphere in a satellite cluster
• Magnetic and electric oscillator flown through the magnetosphere

3

• Magnetic or electric oscillator flown through the magnetosphere in a satellite cluster
• Magnetic or electric oscillator flown through the magnetosphere

4

• Magnetic or electric oscillator measuring in the Earth’s limb or in the platform environment

5

• UV and EUV spectrometer measuring in the Earth’s limb
• UV or EUV spectrometer measuring in the Earth’s limb
