About this exercise type...
Fig e1: SCIAMACHY NO2 slant column over the Pacific
Image courtesy of :
On a summer day, SCIAMACHY measures 2·1016 molec/cm2 NO2 slant column over Bremen, 53°N.
Using the latitudinal distribution of the stratospheric NO2 slant column measured on the same day over the clean Pacific (see Fig. 1), and assuming a tropospheric airmass factor of 0.8 estimate the vertical tropospheric NO2 column for that day.
(_ molec/cm2 − _ molec/cm2) / _ = _ molec/cm2
Entering mathematical expressionsHow to enter mathematical expressions in exercise gaps
| 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. |
