I saw this graph about the electrons density in different altitudes and difference between night and day, the difference between the 2 electron densities (day and night) decreases till 300 Km (F2 layer) and then the difference increases again.

So, I wanted to know why is the recombination rate in F2 layer very low.

May not be necessary for getting a good answer, but if that graph is online, linking it (or even including it directly if copyright permits) could be helpful, especially for those of us not intimately familiar with ionospheric physics. –  Chris White Jan 8 '13 at 15:26
