My satellite is hanging lopsided ...
What will be the right position for the satellite if we want to carry out measurements in the NADIR or LIMB mode? Where do the rays come from? Can you make a correct drawing and fill in the gaps in the text? Print out the PDF-Version of the worksheet for this purpose, either in colour or black and white.
Many simplified sketches give us a wrong idea about the thickness of the atmosphere. Here we had to make one section thicker than it is so that you are able to draw the rays. One of the most fascinating images of our planet is the "Blue Marble" in the NASA Earth Observatory. Here you can see how thin the atmosphere is in reality:
