The choice of scale depends on the data. As noted by @xuanyang02 , you can make your own choice, although there are advantages to sticking with the ranges used for similar data in public archives.
Open ocean data averaged over time and at lower resolutions will have lower maximum values, so a 20 mg/m^3 upper bound misses very few pixels in global level-3 mapped data. Values over 20 are not unusual for individual level-2 files, particularly for coastal areas. Sometimes you want to highlight a feature such as an eddie and may want to chose a range that makes the feature easy to see in printed publications.
