Geospatial analysis of air quality in cities
AtAgforest, we are committed to innovation and sustainability, and in this blog post, we explain how our satellite-based geospatial technology revolutionizes air quality monitoring in Spain.
We will delve into current regulations, challenges and how our solutions leverage advanced satellite technology to provide accurate and accessible air quality data across the country.
Regulations and commitments
In Spain, local entities are responsible for complying with European and national regulations related to air quality. Directives such as 2008/50/EC and decrees such as 102/2011 establish clear obligations, from the measurement of pollutants to the dissemination of results.
Not only do we meet these standards, but we go further by using satellite technology for comprehensive monitoring.
Measurement method and technology used
Traditional measurement stations have limitations in terms of location and number, which hinders an accurate assessment of air quality.
At our company, we have overcome these challenges by developing a web map that uses data from the TROPOMI sensor aboard the Sentinel 5-Precursor satellite. This spectrometer, launched in 2017, detects a wide range of atmospheric pollutants, providing high-resolution, nationwide data.
Mode of operation
TROPOMI sensor
- Full Spectrum: TROPOMI is a spectrometer that encompasses ultraviolet, visible, near infrared and short wavelength radiation. This allows the monitoring of a wide range of atmospheric pollutants.
- Gases Detected: Ozone, methane, formaldehyde, aerosols, carbon monoxide, NO2 and SO2 are some of the gases that TROPOMI can accurately identify.
Spatial resolution
With a spatial resolution of 1 km², each pixel in the images represents an area equivalent to approximately 100 soccer fields. This significantly exceeds the representation of conventional local stations.
Machine Learning for Interpretation
Our measurement method uses Machine Learning methodologies to correlate satellite data with climatic and dispersion variables. This ensures accurate and reliable air quality measurements.
Advantages of our technology
While local stations may have limited representation, our satellite data cover the entire Spanish territory with a spatial resolution of 1km², providing fine detail.
In comparison, the analysis of the Ministry of Transport, Mobility and Urban Agenda points out that conventional stations could fall short even if their number is increased.
We overcome these limitations by offering a complete and detailed perspective.
Commitment to Air Quality
At Agforest, we not only focus on compliance, but also contribute to the development of air quality improvement plans in collaboration with local authorities.
Our satellite technology not only informs air quality, but also drives informed decision making to protect human health and the environment.
To summarize, we are at the forefront of air quality monitoring in Spain using advanced satellite technology.
Our commitment to accuracy, accessibility and collaboration with local authorities makes us a key player in the continuous improvement of air quality.
Stay connected with us to continue discovering how innovation and sustainability converge for a cleaner, healthier future.
