Topographic map

Google +terrain Level lines are easiest to read in the upper left part of the map, from 400 m elevation mark down (other levels unsigned but should go down; higher up would be upwards and right on the map, I think). With this, alleged victims are located lower, like a small alley going down in SSW direction. While winds are opposite. But some of it could slip down if this stuff, whatever it is, is denser than air, and wind is very low (photo, if relevant, suggests that).

I thought the visual map I had was linked here, but it wasn't. This is the correct observation - victims are downhill. The OPCW report decides this is the kill factor, because there was "no discernable wind." But of course that's a bogus conclusion. We can see the wind moving the alleged sarin fog, as it happens, mostly uphill. --Caustic Logic (talk) 11:50, 6 July 2017 (UTC)

densities

air density (at atmospheric pressure) , wiki numbers follow gas law well

t,C rho, kg/m^3

25 1.18391

20 1.2041

15 1.22499

10 1.24663

5 1.26903

Sarin: liquid droplets, 1102 kg/m^3 at 20 C (liquid) by wikipedia; can be (273 +20)/(273 +15)*1102 = 1121 kg/m^3 at 15 C by gas law or a bit higher (comparing 20, 25 degrees densities wiki gives; also compare with water); in any case, about 1000 times heavier. Vaporizes at 160 oC ; in vapor form, heavier than air (molar mass is about 4.9 higher than air). --Resup (talk) 14:25, 8 May 2017 (UTC)
