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).
Special Lines:
– Line showing the freezing point of water
– Line showing the freezing point of CO2
– Line of Mars Tropics and special Circles
Computed data:
– 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)
Geographic use:
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.
