MAQ-Observations: Veenkampen

On https://maq-observations.nl/ we offer all operational measurements from three sites: Veenkampen, Loobos and Amsterdam. These observations include, but do not limit themselves to, temperature, humidity, wind, radiation, soil moisture, soil temperature, energy and carbon fluxes and air quality (e.g. NOx, O3, PM). We offer up-to date charts of the current weather and air quality, as well as a historic dataset to explore, plot and download. You can visualize and download the data with our carefully designed graphical user interface, or download it using a custom tailored API key. We offer up to 627 data streams divided over the three stations at a temporal resolution of up to 20 seconds. The Veenkampen site is located in the ‘Binnenveld’ area between Wageningen and Veenendaal. It’s grass on clay and peat is typical for the area. Its surroundings were converted from farmland into a wetland habitat since 2020. The Veenkampen site is a continuation of the former ‘Haarweg’ and ‘Duivendaal’ sites, which were reallocated because of city expansion. Together they are home to the world’s longest record of global radiation and others. The Veenkampen site is both an operational and experimental site. The focus is on how CO2 and water exchange change with climate and particularly in extremes (droughts, heat waves). With respect to air quality, the site is a background location, without close traffic and industrial sources. The site is operated by MAQ at Wageningen University. It is regularly used by other partners too (e.g. other WUR groups, RIVM). Operationally, we measure meteorology, evaporation, CO2 exchange, soil variables and black carbon concentrations. Experimentally, we measure air quality concentrations and fluxes of NOx and NH3. The site is used for shorter experiments too.

Exclusion of data may consist because, but does not limit itself to, broken equipment, power outages, untrustworthy data and maintanence.

Statement

The source data in the SQL database originates from various sensors. We post-process and quality control the collected data using Python scripts before sending to the SQL database. Near real-time data is submitted every 10 minutes. The data is available at a temporal resolution of up to 20 seconds. Data collection is fully automated and quality-controlled before sending to our database.
