Fig e1: NO2 cross-section at 293 K
Image courtesy of :
After correction for all effects apart from the NO2 absorption, the difference in optical thickness of a satellite measurement between the measurements at 435 and 438 nm is 0.0026.
Using the NO2 absorption cross-section given in the figure, estimate the amount of NO2 along the light path.
SC = 0.0026/(_ cm2/molec)
SC = _ molec/cm2
To which vertical column does this amount correspond if the measurement was taken at 30° SZA and exact nadir view?
AMF = _ = _
VC = SC/AMF = _ molec/cm2
Entering mathematical expressions| General | Spaces inside and outside expressions and the case of characters will usually be ignored. |
| Symbols | Use * for multiplication and / for division. Use ° or deg for degrees. Use conventional function abbreviations, e.g. cos, rad etc. |
| Decimals | E.g. 3.15, 0.02. Use only . for a decimal point. The number of decimal places to be entered will normally be stated in the exercise, if not enter the minimum reasonable number of decimal places. |
| Powers | Enter e.g. 3-2 in the form 3^-2. Enter 3·10-2 as 3E-2 or 3*10^-2. |
