Does anyone know anything about the reason for current increased values? The map shows a cloud of fine dust over the Netherlands and northwest of Germany. My sensors record increasing values since 8:00 p.m. They are are now over 100ppm (PM2.5).
Does anyone know the reason?
Most likely smog and morning fog. In the Netherlands there is a smog alert since friday until today. See In heel Nederland kans op smog door ozon en fijnstof | RIVM for more information (in Dutch).
Seems to be the reason. Thank you, Phaze-III !
Iām in Scotland and my readings for 2.5 and 10 have both been around 80 due to Sahara dust.
