In "Simplified" mode, the results in the analysis are calculated by looking at each instrument's mission objectives: for each instrument we keep track of what the primary, secondary, and opportunity mission objectives are. These mission objectives indicate that an instrument is primarily envisioned to measure variable X, Y and Z, that variables A, B and C are its secondary objective, and that it may offer the opportunity to measure variables I and II although it is not optimized for that. The simplified Gap analysis produces a timeline based on this information. The simplified Gap analysis is only available for analyzing variables, not for missions.
In "Expert system" mode, the results in the analysis are calculated with an expert system. Internally, OSCAR works with a large set of 1700 rules that determine whether or not an instrument is capable of measuring a given variable, and to what degree. When you select "Expert system", the Gap analysis is performed based on this large set of rules.

Variable sorting criteria

 

Each instrument is assigned with a 5-step rating, evaluated as a blend of several elements such as the uncertainty, the vertical resolution, and the frequency and spatial resolution of the retrieved measurement in comparison with the space-time variability of the geophysical parameter.  For this particular Variable, the rating is driven by:

  • the observing technique (active or passive);
  • the utilised MW frequencies.

 

RATING CRITERIA:

1

  • Radar scatterometer

2

  • MW radiometer with 4 frequencies: 37, 19, 10 and 7 GHz

3

  • MW radiometer with 3 frequencies: 37, 19; and 10 and/or 7 GHz

4

  • MW radiometer with 3 frequencies: 19, 10 and 7 GHz; or 2 frequencies: 37 and 19 GHz
  • Cluster of GNSS receivers
  • Large-swath radar altimeter

5

  • MW radiometer at 37 GHz
  • Radar altimeter (only nadir)
