The various data-type diagrams are suggested to be used simultaneously. The diagrams can be used for different purposes in different combinations. In our database various types of data are displayed in separated diagrams. In actual use for educational purposes, the following tasks can be given to students; computing, plotting the values and comparing them to their terrestrial counterparts (measured locally or taken from literature, like here).
– Line showing the freezing point of water
– Line showing the freezing point of CO2
– Line of Mars Tropics and special Circles
– Annual average of temperature
– Absolute min/max temperature (value/date)
– Annual temperature range
– Max./Min diurnal temperature range (value, date)
– Max/min pressure (value/date/season)
– Duration of the frost cover (sols) (number of sols when temperature is below/at the freezing point of CO2)
– Number of sols when temperature can be 0–2 °C
– Number of sols when temperature can be >2°C
– Approx. duration in a sol when temperature is 0–2 °C
– Number of sols when dust activity is high (with dates of a specific year)
– Number of possible freeze-thaw (H2O) / frost-sublimation (CO2) cycles per year
– Characteristic dust storm months
Some phenomena observable in the diagrams:
– Effects of dust storm (crosscheck dust diagrams and day/night temperature): max. temp decreases, min. temp increases.
– Diurnal temperature change in winter/summer: difference is greater in summer
– Effect of solar distance in low latitudes (Equator temperature curve) and high latitudes (length of summer)
– Pressure diagrams: effect of height and tempera-ture (CO2 sublimation) (etc.)
– Change from Viking (1977) to TES (2001) (Higher max. temperatures)
Using the diagrams, lines of spe-cial climatic boundaries are created (for example, line of occurrence 0°C). From these, climatic zones can be defined. These are then correlated (linked) to the ob-served geomorphologic features and then predictions can be make to occurrences of geomorphologic fea-tures (like relaxed craters, polygonal patterned ground etc) or phenomena. Thus, climatic explanation of geomorphologic phenomena can be made.
