MAQ-Observations now on GitHub

We started creating our very own MAQ-Observations GitHub to provide our users with clarity and insight in how we fill our database, and to provide some basic Python API request/post-processing scripts to use our data other than through the web-interface. To this end, we have created a GitHub organization (https://github.com/MAQ-Observations) with two separate repositories: https://github.com/MAQ-Observations/pre-processing…

MAQ Data License updated

We have updated our MAQ Data License for the use of the MAQ-Observations data in publications. We have provided references to the three separate databases (Veenkampen, Loobos, Amsterdam) in our Data License.

Migration of database complete

We have fully migrated our MySQL database (Monday, 2024-04-15). Unfortunately, we had a temporary downtime over the weekend. We thank you for your cooperation and patience.

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. This includes 8 Leaf Wetness streams LWmV1 to LWmV8 which can detect the presence of water or ice on an artificial leaf (https://www.campbellsci.com/lws). The data is available from 2023-08-07 onwards and is updated every 10 minutes as usual. These 8 steams have been added…

Teledyne (O3, NO, NO2) data now available for Veenkampen

At Veenkampen we have Teledyne T200 and T400 instruments to measure ozone (O3), nitrogen oxide (NO) and nitrogen dioxide (NO2) as important indicators for air quality. This data is now included in the Veenkampen database and it goes back until January 2022. Feel free to explore our newest data addition to the website. The O3,…

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…

MAQ-observations nearing its offical launch

The web-developers have made significant progress and improvements on the MAQ-observations web page over the last weeks. Some notable improvements are: A different database structure that allows for downloads of a much larger volume (both timespan and number of streams). A waiting queue functionality that will send the data to you via email once the…

Update on Veenkampen measurements

Spring is arriving with sunny but cold weather conditions. In the coming weeks we will deploy a high quality particulate matter PM2.5 instrument at Veenkampen.

New Loobos ecosystem site turning into an attractive research infrastructure

In March 2021, a new 38 m tall tower was built in Loobos, near Kootwijk. Along with the 6 m sea container, the site is becoming an attractive research infrastructure. Researchers from Wageningen University, Utrecht University and TU Delft have installed various sensors. The aim is to obtain the ICOS Ecosystem station label in May…
