Lowest transmission through the atmosphere
Did you know?
Low levels can be caused by at least three basic reasons: low transmit level, for example Wi-Fi power levels; far-away transmitter, such as 3G more than 5 miles (8.0 km) away or TV more than 31 miles (50 km) away; and obstruction between the transmitter and the receiver, leaving no clear path. Meer weergeven Radio propagation is the behavior of radio waves as they travel, or are propagated, from one point to another in vacuum, or into various parts of the atmosphere.

WebThe outgoing radiance from the earth's surface traverses the atmosphere to the sensor. The transmittances of the atmosphere along a nadir view path and along a view path at 40° from nadir are shown in Fig. 2-7. These curves differ from the one in Fig. 2-4 only by virtue of different path lengths through the atmosphere.
