My apologies if this post hit the wrong topic. I was wondering if it's possible to "see" the wind by means of an spectrometer or a similar device. I'm aware that light passes through air and it does leave behind some portion of it's wavelength through absorption, and this is invisible to the human eye thus we can't see it. If it's impossible to perform such thing, how about other properties, maybe water molecules. Could these be seen? Please note that I'm referring to a small, micrometereologic scale, for winds inside a person's seeing range, and not from a macroscopic view. Thank you.
