EXI coverage requirements | |
---|---|
Diurnal requirements | In any given span of 10 days, the four 3-h intervals spanning from 6 am to 6 pm local time are sampled with at least 80% longitude coverage in: ≥ 3 local time intervals for all latitudes equatorward of ± 30° ≥ 2 local time intervals for all latitudes equatorward of ± 50°. In any given span of 10 days, at least one of the four 3-h intervals spanning from 6 am to 6 pm local time is sampled with at least 50% longitude coverage for all latitudes equatorward of ± 80°. |
Geographic requirements | ≥ 80% of the Mars geographic area is sampled more frequently than every 72 h. Latitudes ≤ 80° are sampled more frequently than every 72 h. |
Seasonal requirements | Observations over one full Martian year (goal: 20 out of the 24 LS intervals of 15° are included). |
