Apprendo ora che grazie all'effetto Doppler si può misurare la velocità dei venti da un satellite. A me una notizia così mette di buon umore.
The UV laser transmitter [...] emits short and powerful pulses of UV light towards the atmosphere, which is then reflected by the molecules and particles that move under the action of the wind at different altitudes. By measuring the wavelength of the return laser light, the instrument can calculate information relating to the wind speed. It is a totally innovative approach in measuring the wind from the space.
