Questions & Answers

Q: How has Bogota been measuring air quality?

Bogota has developed a network of census equipped with scientific-grade sensors that measure various air pollutants and atmospheric conditions at 20 strategic locations throughout the city.

Q: What is the goal of the air quality mapping project in Bogota?

The goal is to provide citizens with real-time measurements and forecasts of air pollutants, improving the existing air quality mapping application.

Q: What are the two additions to the air quality mapping system in Bogota?

The first addition is the ability to make estimates of air pollutants at a sensor station even when the sensor is temporarily offline. The second addition is an improved interpolation map for more accurate estimates of air pollution in between sensor stations.

Q: What is the city's long-term goal for air pollution management in Bogota?

Bogota aims to manage and reduce air pollution levels to have 70% of the city within recommended healthy limits for air quality by 2030, compared to 25% in 2015.

Summary & Key Takeaways

• Bogota, the capital of Colombia, has developed a network of sensors to measure air pollution throughout the city.

• The city aims to improve its existing air quality mapping application by providing real-time measurements and forecasts for air pollutants.

• The project involves two additions to the system: creating estimates of air pollutants when sensors are temporarily offline and improving interpolation maps for more accurate estimates of air pollution.
