The result I'm getting seems to be a percentile value for hourly observations.\r\nFor example, for 2012 in Aberdeen Union Street, there are 3 days when daily mean of 50ug/m3 is exceeded, but the Scottish 98.08th percentile result is 55 ug/m3\r\n\r\nI wondered if there was a way to get the percentiles for the daily concentrations using aqstats, in line with the Air Quality Objectives.\r\n\r\nThanks\r\n\r\nAlan"}}
