Pollen

We’re measuring pollen!

We are running our airminer 2.0 sensors to calculate local pollen levels. As expected, pollen levels vary with temperature and precipitation, but we also see significant variations through the day.

When to expect birch pollen in Norway?

Hazel and alder is flowering in Southern Norway, but the key allergen to many of us is birch. When can we expect the birch pollen season to start?

Spring in Europe – alder, hazel and birch pollen

We are heading into warmer and lighter days in Europe, lockdowns or not. And no surprise, the pollen is faithfully here.

Birch pollen – how did it develop?

The birch season is over for this year - we have dived into our data and created a visualisation of how it developed in Europe.

Grass pollen levels still high in Central Europe

High levels in Denmark, Germany and Poland, France may have seen the peak. Grass pollen in UK and Scandinavia is on the rise as northern Europe really warms up.

Grass blooming in Central Europe

The grass season is long - and Central Europe is in the midst of the blooming. Northern Europe is starting to feel the season.

Birch pollen – the north gets the rest

The birch pollen season is almost finished in most of Central and South Europe. The inhabitants of the northern regions can still expect moderate to high levels, as the weather (finally) warms up.

A first look at the grass pollen season

Grass pollen is the most common pollen allergy in Europe and the season is well under way. Central Europe can expect high levels, while the cold weather further north let us wait for the spread.

The accidental badger detector

PM2.5 levels peaked late at night and early mornings at our sensor test site and we struggled to find out why. Turns out the answer had fur and four legs.

Green in India means red in Norway

We've attempted to compare the different PM2.5 breakpoints in selected air quality indices. It turns out a green level does not mean the same around the world.

EU’s clean air outlook – saving lives and reducing costs

EU has launched its Second Clean Air Outlook report. There are both premature deaths and money to be saved by improving the air quality.

Pilot testing our air quality monitor – where is the pollution coming from?

We are pilot testing our air quality monitors and have started to dig into the first results. We had expected local variations in PM-levels, but it turns out the source is probably found far away from the neighbour's wood burning stove.

Air quality in Europe – it’s going the right way

EEA's recent report gives hope for the air quality in Europe. Most pollutants have been reduced the last decade, but Eastern Europe is still heavily affected.
