Lentesmog or Spring Smog

[VRT article Lentesmog](https://www.vrt.be/vrtnws/nl/2026/03/23/daar-is-lentesmog-weer-fijnstof-door-bemesting-en-verkeer/)

„Particulate matter levels in the air peaked last week, and we will experience elevated concentrations again today and tomorrow. This is due to an old acquaintance that rears its head almost every year: spring smog. It is caused by a combination of fertilizing farmers, emissions from cars and wood stoves, pollen, and stable spring weather, and is particularly bad news for people with lung and heart conditions.“

Zou wel eens die kaart willen vergelijken met de kleuren van neem 10tal jaar terug, kans bestaat dat die der helemaal anders uit ziet.
