About cloud density

I mean, if we wanted to be super technical, we can specify altitude for each cloud density for low, mid and high ends + make a chart with varying densities.
But iirc, cloud density came from a calc Darkanine made, it was an average.
Dont quote me on that tho. I know OBD accepted a different value for this guy, but even that density was a lowball.

The OBD also uses 1.003 kg/m^3. They have used that value twice while calc'ing a couple of cloud related feats in the HST.
I would like to know the exact source though.

1.003 kg/m^3 is the density of the atmosphere at cloud height, where the density of the atmosphere decreases as you go further up into the atmosphere.
It is also the reason why the density of the atmosphere is 1.225kg/m^3 at ground level, but negligible once you reach the stratosphere.
0.5 grams, or the density that Kaltias posted is the density of actual clouds, which is mostly an aerosol composed of condensed water from the water vapor in the atmosphere at that height.
EDIT: I failed to noticed that this was moved to ther calc section. Sorry.

Density of clouds vary depending of the source. From the first page of google:
- From 0.03 to 3 g/m^3 depending of the type of cloud.
- From these two is 0.5 g/m^3. Also this says basically the same.
- Vary from 10.5 to 17.5 g/m^3 (these were calculated).

others, sources about 1.003 kg/m┬│ (The last one are offline, use WayBackMachine to see the old entries).

Similar to this, it calculated the density in 1.003 kg/m^3. I think that the lower values is the weight in water (like 1 m^3 weight 1.003 kg, but it has a water mass of at least 0.03 g).

Guess it's settled, then.

Maybe we should put the source for cloud density in our Calculations page?

The part of clouds that's water vapor is 3g/m3 at best, the rest of the weight comes from the air density at such altitudes.

Yes, Kaltias added the value to the Calculations page.
