Dobson unit. 돕슨 단위

 

---------------------------------------------------

 

The Dobson unit (DU) is defined

as the thickness (in units of 10 μm) of that layer of pure gas

which would be formed by the total column amount

at standard conditions for temperature and pressure (STP).

( 출처 https://en.wikipedia.org/wiki/Dobson_unit )

 

 

 

1 DU → 10 μm

10 μm = 0.010 mm = 0.001 cm

 

 

 

One DU is also equivalent to 2.687×10^20 molecules per square metre.

1 Du = 2.687×10^20 /m2
