пирометр на андроид Атмосфера земли практически полностью прозрачна для инфракрасного излучения 8-14 мкм и незначительно непрозрачно в диапазоне 3-5 мкм. Для практического использования это ничтожно малая величина. Поэтому мы измеряем температуру любых доступных в прямой видимости объектов, например облаков.

April

с альбома Deep Purple

April is a cruel time
Even though the sun may shine
And world looks in the shade as it slowly comes away
Still falls the April rain
And the valley`s filled with pain
And you can`t tell me quite why
As i look up to the grey sky
Where it should be blue
Grey sky where I should see you
Ask why, why it should be so
I`ll cry, say that I don`t know

Maybe once in a while I`ll forget and I`ll smile
But then the feeling comes again of an April without end
Of an April lonely as they come
In the dark of my mind I can see all too fine
But there is nothing to be done when I just can`t feel the sun
And the springtime`s the season of the night

Grey sky where it should be blue
Grey sky where I should see you
Ask why, why it should be so
I`ll cry, say that I don`t know
I don`t know
