Mobile monitoring

Real-time, hyperlocal mapping of air pollution covering arterial roads, residential zones and other areas of pollution vulnerability.

In the city of Bengaluru, we have 10 real-time regulatory grade monitors, which tell us the ambient air quality of the city. The pollution levels we get from these is very different from the actual levels of exposure the citizens face at various locations. There is deep mismatch between ambient levels of air quality measured this way and actual exposure that Bengalurians face. The air quality is actually much worse both in the pollution hotspots that are known, as well as in unsuspecting areas, such as residential streets or public spaces.

Real-time fixed monitors are extremely expensive, and we can never actually have enough spread across all localities of the city, to know what exactly we are breathing in each place. There is the option of using low cost monitors, which are easily available in the market, but the data quality from these has not matured to catch up to reference grade.

Globally, cities are taking to mobile monitoring to generate detailed, street-by-street maps of air pollution to push for emission reductions. Oakland, London, and Houston all have undertaken this exercise, with London flagging off its program in January 2019.

This programme will identify localised pollution hotspots, by mapping pollutant concentration along pre-designated roads and routes across Bengaluru. This is done by fitting high-grade air quality monitoring equipment in a vehicle, which then travels around the city, generating highly localised data.

The monitoring exercise is expected to focus on areas of interest such that it has a high probability of influencing decision making to improve the city’s quality of air:

  1. High Traffic Density Corridors (HTDC) – to demonstrate the high levels of pollution, that the city experiences that often go unrecognised and has an impact on commuters, and the people living around these major roads.
  2. Neighbourhoods/localities – to assess the quality of air in areas where people spend most of their time, to live and work. Neighbourhoods are also a key focus since they have become unsuspecting victims of pollution where the impact due to the steep rise in through-traffic passing on the residential streets, waste burning at street corners, accumulating road dust and rampant construction activities, remains unknown.
  3. School and Hospital clusters – make for some of the most vulnerable areas, so from the perspective of understanding exposure and threat due to air pollution, they need to be in the measurement route. The focus will be schools in the central business district of Bengaluru.
  4. Public spaces – to demonstrate the air quality in areas that are often associated with cleaner environments such as lakes and parks.


The Clean Air Platform is looking for collaborations with:

Frequently Asked Questions

Mobile monitoring involves the use of a moving vehicle to map, in real time, the quality of air in areas of interest. Traditionally these mobile monitors needed to be stationary while measuring air quality. With the use of specific technologies, it is now possible to measure the air quality even while the vehicle is in motion. Oakland, Houston and now London are all employing this method to map their respective cities.

Bengaluru has what is called a ‘blue sky’ problem, that is, when we see clear skies we assume the air is clean. CSE found that in certain areas of Bengaluru, the air pollution was 12 times higher than what the background ambient levels were. This exercise will help the city identify its air quality hotspots, help home in on specific sources, and catalyse mitigation action.

We are looking to find partners who will help undertake this first of its kind study in India. Work closely with them to deliver on the local level maps and insight and then subsequently engage with communities identify problems and work towards solutions

The Clean Air platform along with its Technical Advisory Committee will be overseeing the projects. We also hope to give you regular updates on the progress of the project through our website, twitter etc.

Clean Air Platform has the necessary funds for this project, and will be the core funder. But as with all good things in life, the more the merrier. We are open to like-minded and committed partners to co-funder this project

Organisations with experience in conducting similar studies with a passion and commitment to this work. Also, some sort of presence in Bengaluru or partnership would be a good to have.

We are glad you asked! Please write to us directly at [email protected]

No, it can be either. But remember, this is a public service exercise with a charitable intent which means commercial rates may not be feasible for us to engage with you.

12 months, but final details will be based on the winning bidders proposal

We encourage all kinds of partnerships but will interact largely with the primary bidder and a single point of contact.

Yes, but much like above, our point of engagement and responsibility of final deliverables will rest with the primary bidder.
