The graph on the right side which always shows 400,000 years of
temperature anomolies from modern times, derived from the Vostok Ice
Core sample. As the three main elements of Earth orbit changes are enabled (see Checkboxes, below), a magenta-colored line plot is made which combines the simple sine ways of each element according to their periodicity.
There is also a vertical slider on the left side of this graph which allows certain elements (again, see checkboxes below) to be changed to show their position or orientation back through the millennium.
The Earth-Sun system which depicts the Earth in orbit around the
Sun, as controlled by the various checkboxes. The applet begins with a caveat about the relative sizes of the elements.
The view button toggles between showing a projection which is
above the orbital plane and one which is more sideways.
The Label checkbox which toggles the seasonal labels on/off. The default is on.
The eccentrictiy checkbox which enables (when checked) the
orbital eccentricity to change when the "millennia slider" is
used. The eccentricity curve displayed is a combination of the
95, 125 and 140Kyr cycles.
The precession checkbox which enables (when checked) the
precession of the Earth axis to change when the "millennia
slider" is used. The precession curve displayed is a combination
of the 19 and 24Kyr cycles.
The tilt checkbox which enables (when checked) the tilt of
the Earth axis to change when the "millennia slider" is used.
The tilt curve displayed is the 41Kyr cycle.
The "lock season" checkbox which will cause the seasonal position in place when checked to remain as the "millennia slider" is used.
The "rotation" checkbox which (when enabled) shows the Earth in its daily rotation about the axis.
The "orbit" checkbox which (when enabled) causes the orbital motion of the Earth to be in correct proportion to the rotation.
The "faster orbit" checkbox accellerates the orbital motion
This applet is a work in progress! It was coded in ActionScript version 3, and requires
Vostok Core Data obtained from:
Orbital information obtained from various sources.
