Estimated share
19%
Indicative estimate of the PM10 share attributable to dust in the latest reading.
Local PM10/PM2.5 ratio
2.1
Calculated from clean hours within the same range.
This attribution is indicative only: it uses a simple rule based on AOD and PM2.5 to separate local background from Saharan contribution, and it may under- or over-estimate complex episodes.
