Meersens API platform handles more than 150 pollutants and parameters, giving you new ways to achieve your goals & improve your operations.

Air quality

The Meersens API provides geographic and temporal aggregation to get targeted air quality data for a specific location. Easily access pollutant concentration levels, reliable information, rigorous comparisons with WHO standards and get generic health and behavior recommendations.

Pollen

Pollen allergies are a major cause of chronic illnesses. With our pollen API, you can access specific pollen data for any location. Get pollen concentration levels, data reliability, comparisons to WHO standards, as well as relevant health recommendations. Take control and safeguard your well-being!

Noise pollution

Noise is the second most harmful environmental factor in Europe, after air pollution. Our noise API provides average noise levels for a specific location, including mean levels, data reliability, comparison to WHO standards, and health recommendations.

Tap water quality

Water is a vital element for the survival of life on Earth, but unfortunately, it is also among the primary sources of environmental pollution, alongside air pollution. With the dedicated API for water quality, you have the opportunity to obtain valuable information regarding tap water in a specific location. This information includes pollutant concentration levels, data reliability, compliance with WHO standards, and general recommendations to preserve health.

The UV spectrum consists of three types of radiation: UVC, which is entirely absorbed by the atmosphere, UVB, partially absorbed, and UVA, which is weakly absorbed. With the UV API, you can easily obtain information about the UV index for a specific location. This information includes the UV index itself, data reliability, comparison with WHO standards, and general health recommendations.

Weather

Air quality is influenced by various factors, including pollutant emissions from diverse sources such as industry, transportation, tertiary and domestic activities. However, it is also subject to the influence of weather conditions, which govern the dispersion or, conversely, the accumulation of these pollutants. With the help of the weather API, you have the opportunity to request specific weather data for a given location. This information allows you to better understand the meteorological parameters at play, thus gaining a better understanding of their impact on air quality in the concerned region.

FAQs

Everything you need to know about our environmental data APIs. Can’t find the answer you’re looking for? Contact us.

How are Meersens data calculated?

Meersens collects and aggregates open data (meteorology, satellite, traffic, soil compositions, etc.), and with machine learning technology, it can provide reliable and accurate environmental quality modeling anywhere on the planet and at any time.

It is possible to access historical data up to 3 years back (up to 6 months : hourly granularity ; daily : beyond). Predictive data goes up to 96 hours.

What is the accuracy and reliability of the data?

The data accuracy is 50×50 meters in metropolitan areas. In rural zones, the accuracy may vary. The guaranteed data reliability is 92%, and it can increase in urban areas where more data can be collected and aggregated.

How do the environmental quality indexes work?

The indexes are provided by health organizations (European Environment Agency for EAQI, Air Quality Monitoring Associations for ATMO) or have been created by Meersens for MAQI. Based on the value returned by the modeling at a given moment, the index assigns an indicator of environmental quality (good, moderate, poor, …), along with associated risks and behavioral recommendations. The Meersens MAQI index takes into account WHO standards and specifies the duration of exposure before it poses a health risk.

What happens when the monthly call volume is fully consumed?
