Chapter 3 _________________________________________________________ Ozone Calculation
VAISALA_______________________________________________________________________ 95
The following equation gives the result in DUs when the partial
pressures are given in mPa and ambient pressures in hPa.
Residual Ozone (Total Ozone after
Balloon Burst)
After the balloon burst, the level of ozone is estimated by using the
equation below with a constant mixing ratio (p
3i
= p
3i+1
= p
3END
) up to
ambient pressure 0 hPa. The equation changes to:
When the pressure is given in hPa, the equation above gives the residual
total ozone in DUs.
The total ozone can now be calculated from the equation:
Another option is introduced in the GAW report 201. Post-calculation
is possible, integrated ozone is reported, and residual can be calculated
afterwards. It can also be changed in the script.
