    Hi Everybody;

    As the sun plummets into the solar minimum a new index is derived to measure the total energy budget of the planet. The heating of our planet is caused by the sun and the atmosphere that traps this energy. It converts high energy photons such as X-rays and ultraviolet radiation into heat.

    Space is cold even when solar radiation is present. Once the radiation hits a media such as our planet is converted into heat and trapped by the atmosphere. Planets or moons that do not have a thick layer of gas surrounding it will be extremely hot during day and very cold at night. We are lucky to have a thick layer of gas here on earth and it moderates the temperature so that life is possible.

    The Thermosphere Climate Index (TCI) is similar to the Solar Flux (SF) but will provide a more meaningful indicator in how much energy our planet stores in the atmosphere.

    GA Alex,

    Interesting information. There is one thing I don't understand about the graph. That is the temperatures on the left side. It shows the temperature in space to between 700 and 1200 degrees K. while the temperature near earth is about what I would expect. I understood space was cold not hot. ??

    Hi Dave;

    Space is only cold and dark when it is devoid of molecules that can transform the radiation into a wave length that we can see or feel. The radiation intensity in the Van Allen belt is extremely strong and since there are still some molecules present it can be measured as heat. As the air thins out, to almost nothing, measuring temperature is not really possible. The thermometer's mass and type would affect the measurement severely.

    All the best and 73;

    Dont let Al Gore know that it is the Sun that heats the planet! Hes still trying to convince the world its cow farts.

    "Cow farts" are considered a green house gas and it traps heat by making the earth more opaque to infra red. So instead of the heat escaping into space it is trapped. The same thing happens on cloudy nights in the winter that are usually warmer than clear nights.
    This new Thermosphere Climate Index (TCI) will definitely be able to show that this is actually happening!

    All the best;
