CLEAIR AIR POLLUTION – Monitor, Measure, Analyse and Act

Mission

Why

Air pollution is in the top 10 risks worldwide & the top 6 risks in developing countries in Asia
Air pollution kills 4.5 million people a year

But these figures hide what can be highly local, personal risk.

Air quality can vary sharply even within the same city block, and pollution exposure can vary 30% between individuals living in the same residence

What

Cleair helps us understand at a local and personal level where pollution is, where it comes from, and its impacts on us
Data insights delivered by Cleair Analytics can be used to make effective pollution management decisions
By making air pollution visible and measurable, Cleair provides a more comprehensive picture of air pollution across cities allowing us to manage pollution better

How

Measuring pollution variation over short distances in real time providing a more granular and effective picture of air pollution across cities
Leveraging data from existing monitoring infrastructure along with data from an optimised network of low cost sensor devices Cleair uses state of the art AI modelling to accurately measure localised pollution and its variation over short distances
The Cleair Device detects concentration of major air pollutants PM2.5, PM10, NO2 and Ozone along with temperature, pressure & humidity
Powered by AI and deep learning models, Cleair collates data from various open sources including other devices and available satellite data to provide useful insights at a granular level
Cleair Analytics comes with powerful visualisations to track local pollutant levels over times and across location to provide better insights on the local pollution and its exposure

Platform

THE DEVICE

A low cost, modular, pluggable I-T based air pollution measurement device
A network of these open source devices can be deployed to measure & analyse air pollutants in real time to a high degree of accuracy
The devices communicate directly with The CLEAIR CLOUD to provide real time data

THE CLEAIR CLOUD AND ANALYTICS

The Cleair Cloud collects millions of these measurements from its network of Cleair devices and other third party open sources including government data.

Using powerful AI algorithmns, The Cleair Analytics platforms converts these data into meaningful insights that can highlight pollution variation over time and location, identify and predict local hotspots or highlight the times of days with highest pollution levels
The platform enables notifications and alarms to be easily configured for monitoring purposes such as monitoring of specific air pollutants, recording images of pollution sources, recording threshold alarms
The portal provides various dashboards to sho w pollution development in real time and generate historical snapshots

Projects

World Bank funded electric vehicle project in Kolkata, India

Fleet electriﬁcation is one of the strategies for improving urban air pollution in Kolkata. The project identified high polluting corridors in Kolkata using low cost sensors and these corridors were selected for EV deployment. Data is being collected over two years with a network of sensors and shows the following results:

Smart City Solution – New Town, Kolkata

Cities across the world have understood that now is the time to move towards clean mobility and have already begun to remodel their urban space with more emphasis on walking and bicycling. Cleair route finders calculates alternative routes with the lowest concentration of pollutants in New Town, Kolkata made available to citizen via the Cleair app.

Varanasi Cleair Air-Quality Network

Varanasi is one of India’s historic cities and a prime tourist destination is also one of the most polluted. Cleair’s Varanasi deployment creates a hyperlocal network in a city which only has one monitoring station and will provide critical insights on the spaiotemporal variation as well as identify hotspots allowing.

Cleair Route Analysis Model

Several studies showed a correlation between long-term exposure to air pollution and increased likelihood of death from COVID-19, likely due to poor lung health. Even short-term improvements to air quality may be helping to reduce the number of deaths from other respiratory illnesses. Cities across the world have understood that now is the time to move towards clean mobility and have already begun to remodel their urban space with more emphasis on walking and bicycling. Cleair route finders calculates alternative routes with the lowest concentration of pollutants along each route made available to citizen via the Cleair app.

S12 East-West corridor route shows. The route is mostly polluted throughout as it starts from Howrah Station, central Kolkata, and pollution level eases as we move to Salt Lake Route close to Sealdah Railways station is severely pollution

S9 North-South corridor route shows. The route is more polluted in the northern part as well as in the Rash Bihari Avenue. This route runs along the Hooghly river and it shows a lower level of pollution alongside the river, And towards the south-western end

Geospatial Temporal Models

COVID-19 lockdown caused most public transport, Factories and construction work suspended have brought the world to a standstill.

The scenario has led to a major cut in air pollutants and cities are recording much lower levels of harmful microscopic particulate matter known as PM 2.5, and of nitrogen dioxide, which is released by vehicles and power plants. Amid the changes brought by COVID-19, we have analyzed the change in particulate levels (PM2.5) concerning the lockdown and with respect to levels in the year 2019 vs 2020.

The results showed a drop of around 30-40 in 2020 compared to 2019 in the city of Delhi and Kolkata India. We could also see a drop in PM levels in Delhi due to the lockdown.

Expertise

We leverage our partnership with a network of atmospheric & data scientists nd experts from Johns Hopkins, Columbia University, UC Berkeley to test, validate and forecast. Cleair uses the latest research findings from these institutes in areas such as positioning of devices, modelling of pollution data and presentation of insights.

Our partnership

Cleair has partnered with Move LA to champion strategies to accelerate Move LA’s goal to foster cleaner and healthy neighbourhoods where people of all ages and incomes can live, work and thrive.

Cleair has partnered with Smart Pandemic Management @UC Berkeley to address the joint challenges of reopening the economy and managing subsequent outbreaks. Long-term exposure to air pollution has been linked to an increased risk of dying from COVID-19. Cleair’s analysis of air pollution in Kolkata indicates a coarse corelation between Covid 19 severity and bad air pollution.
