Gap analyses by variable or by type of mission

Please select either a variable or a type of mission to display a time chart of satellite instruments having the potential to provide the corresponding measurements. The selection is based on design characteristics (Expert analysis) or declared mission objectives (Simplified analysis). Such a preliminary analysis does not replace a detailed assessment of the actual instrument performances, data availability, and quality of derived environmental data records against specific user requirements.

Note: The chart can be sorted by clicking on the header columns and filtered by instrument properties when applicable. Select the period of interest with the cursor at the bottom of the chart. Future missions which are not firmly planned are shaded with stripes. A warning icon (Important note) indicates degraded satellite: hover over the icon for details. The chart is followed by a table of all potentially relevant instruments.

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.

Relevant instruments and their contribution

The sorting column describes how the instruments, by design, have the potential to contribute to certain pre-determined capabilities, assuming nominal operation of space and ground segments. For this particular capability, instrument performance is considered to be driven by:

  • the spectral band (short-wave or infrared or millimeter-submillimeter wave);
  • the spectral scanning mode (spectrometric or filter radiometric);
  • the vertical scanning mode (active scanning or by occultation).

 Sorting criteria and colour code:

  1. UV/VIS/NIR/SWIR spectrometer with resolution <=1 nm in UV and SWIR, and <=1.5 in VIS and NIR.
  2. UV/VIS and possibly NIR spectrometer with resolution <=1 nm in UV, and <=1.5 nm in VIS and NIR.
  3. IR spectrometer with resolution <=0.05 cm-1 in MWIR and TIR, OR Mm-submm spectrometer in the range 60-250 GHz or possibly 60-650 or possibly 60-3000 GHz.
  4. Very-high resolution spectrometer operating on lines in VIS and NIR with resolution <=0.03 nm; OR on lines in the range 307.9-309.4 nm (for OH).
  5. Occultation spectrometers.
