- All the counts were originally counts per cubic meter of air per 24 hours according to protocol of IAA. Pollen calendar for each month was constructed, but it was huge data, which could not be adjusted in this article. These counts were rounded off to counts per cubic meter of air per hour in a month due to limitations of paper.
