Re: "micron" to kg/m^2 conversion

Hi all,

I've recently interacted with Astronomers regarding precipitable water
vapour content in the atmosphere. They seem to measure the PWV in
microns, while meteo people appear to be using kg/m^2. Does anybody
know how to convert between the two? A cursory google search yielded
absolutely nothing.

Thanks!

Hi,

If you pour one kilogram of water (about one liter) on a square feet of ground, you obtain a layer of water of 1 mm of height, i.e. 1000 microns.

Maybe your thinking of the infrared emissions _from_ the water, where microns count the wavelength of light being imaged/measured/etc., not the quantity of H20. ... Higher H20 levels would will inhibit observing at the wavelengths that are partially attenuated. ...
