About this layer

Climatological averages from the Mars Climate Database — not real-time observations. Read each value as a long-term mean for the selected season and time of day.

• Ls (areocentric solar longitude) is the season angle. 0° = northern spring equinox, 90° = northern summer solstice, 180° = northern autumn equinox, 270° = northern winter solstice.
• LTST is local true solar time in 2-hour steps.
• Grid is 5.625° × 3.75° (~330 × 220 km). Position inside one cell does not change the value.
• Wind is the climatological mean surface wind vector, not gusts or instantaneous flow. It drives the Monte Carlo cloud drift.

Limitations: coarse grid, one dust scenario at a time, no storm-scale events. Use for planning context, not final engineering numbers.
