Final migration of database

We will be finalizing the migration of the MAQ-Observations.nl MySQL database this Friday (April 12th). This means that our near-real time data will not be updated. We will resume our near-real time data services in the evening. Historical data will remain available. We are sorry for the inconvenience that this may cause.

Migration of database

We will migrate our database during the coming weeks (up to 12-04-2024). This might cause some inconvenience and downtime of our services.

MAQ-Observations.nl now live

The Meteorology and Air Quality group of Wageningen University & Research runs three sites, where we collect meteorological and air quality measurements. The three sites are carefully chosen to represent the most frequent land cover types in the Netherlands: Veenkampen has grassland on peat, Loobos has Pine forest and Amsterdam as urban conglomeration. In general,…

12 new streams added for Loobos

We have added 12 new streams for the Loobos site today.

Particulate matter data now available for Veenkampen

We have added two new streams to the Veenkampen site: PM2.5 and PM10. The data is also part of the advanced ‘Composition’ package at Veenkampen. Particulate matter (PM) is damaging for human health and is therefore often used in studies about air quality. At Veenkampen we have the data available for particles smaller than 10…
