Answer:
Northen hemisphere (-OH) concentration:
Given
CH3CCl3 → OH
MCH3CCl3 = 133.4 g/mol
Volume of atmosphere = 5.1*1024 cm3
Global CH3CCl3 production = 5.8*1011 g/yr
Northen hemisphere production = 95% of total emissions
95%of the total productions = (95/100)*5.8*1011 gr/yr = 5.51*10 11 g/yr
kOH = 6.7*10-15 cm3 moles-1 s-2
OH = (5.51*1011)/(6.7*10-15)
= 0.822 *1026
Out of which (0.781*1026) will produce in northen hemispehere.
2. Estimate Northern and Southern hemispheric average OH concentrations by setting up a box model utilizing...
5. (a) 4points Figure 2 below shows the annual average radiation budget as a function of latitude. Estimate the latitude Lc where the net radiation crosses over from positive to negative in the Northern Hemisphere. Also estimate the value of the net radiation at the North Pole. Use the two pieces of information to find the equation of a straight line that approximately describes the net radiation (in WIm2) as a function of latitude L between 10 N and the...
