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.
