We started our project as a group of enthusiasts who were faced with severe air pollution and a lack of up-to-date data. Now our unique expertise has created a new way to measure air pollution through an open community. Collaborate to reduce emissions and protect public health.
Make environmental data open and accessible to the world
Nebo is a distributed, dense network of precision sensors combined into an open platform that enables an independent air quality measurement system for people in the B2C segments as well as for organizations in the B2B and B2G segments.
What is Nebo
How it works
Let's clean the air
Make your city cleaner
It's a platform where users can self-transmit data in the open using small sensors. Measure air quality, predict pollution, and improve your.
Engage your community
City dwellers install compact devices outside their windows that measure the level of air pollution. All the sensors are automatically combined into an open network. The more sensors installed in one area, the more accurately they can detect and predict the level of pollution.
Clearer than ever
The first step to change is realizing what you can't see with the naked eye: the air we breathe every day. With Nebo's online platform, you can easily check the air quality in your neighborhood.
As cities grow, the number of environmental problems increases
In most large cities, pollution levels are measured with specialized stations. But such stations work only within 1-3 km and download information within a few hours or a day.
Nebo offers the most affordable range of air quality monitoring services to relieve you of the tedious and expensive work of air quality management so you can fight for clean air.

We make air quality measurement easy.

No separate purchase of software. No additional setup and installation with the knowledge of a technician. No additional costs.
We provide you with open information from all instruments to eliminate all air quality blind spots with NeboAir sensors.

Our system also accepts monitoring data on other pollutants from our partners. To combine the data, we use the AQI, or Air Quality Index, a system for translating sometimes confusing measurements of pollutant concentrations into one easy-to-understand scale to clearly represent the health risks associated with ambient air pollution
The index formula typically takes into account up to 6 major pollutants (PM2.5, PM10, carbon monoxide, sulfur dioxide, nitrogen dioxide, and ground-level ozone) and calculates the corresponding health risk (or AQI count) for each at any given time. The total number of AQIs at a given time is determined by the most "dangerous" pollutant with the highest number of AQIs.
The index ranges from 0 to 500, where high index values indicate higher levels of air pollution and higher potential for adverse health effects. For example, any value greater than 300 is considered hazardous, while an AQI value of 0-50, on the other hand, represents good air quality.

Why is it important to know the level of air pollution?
Air pollution is caused by gases and particles emitted into the atmosphere by a variety of human activities, as agriculture, and farming and the inefficient combustion of fuels. There are also natural sources contributing to air pollution, including particles of soil, dust and salt in sea spray.

Air pollutants can be emitted directly from a source (i.e. primary pollutants) or can form from chemical reactions in the atmosphere (i.e. secondary pollutants). When concentrations of these substances reach critical levels in the air, they harm humans, animals, plants and ecosystems, reduce visibility and corrode materials, buildings and cultural heritage sites.

The main pollutants affecting human health are particulate matter, ground-level ozone (O3) and nitrogen dioxide (NO2). The fine particles that damage human health are known as PM2.5 (particles with a diameter of less than 2.5 micrometres), which can penetrate deep into the lungs and pass into the bloodstream affecting different organs and bodily functions. These particles can either be emitted directly or formed in the atmosphere from several different emitted pollutants (e.g. ammonia (NH3), and volatile organic compounds (VOCs)).

Ozone (O₃), is an important secondary pollutant. It is a potent lung irritant and stunts growth in plants. It is also a powerful greenhouse gas (GHG). O₃ is formed in the troposphere, near the Earth's surface, when certain precursor pollutants react in the presence of sunlight. The powerful GHG, methane (CH₄), is responsible for a significant portion of O₃ formation. This tropospheric ozone is different from the ozone in the upper atmosphere (stratosphere), which protects us from ultraviolet light from the sun.

Nitrogen oxides (NOx) are a group of air polluting chemical compounds, comprising nitrogen dioxide (NO2) and nitrogen monoxide (NO). NO2 is the most harmful of these compounds and is generated from human-driven activities. It impacts human health, reduces atmospheric visibility, and can play a significant role in climate change, at high concentrations. Finally, it is a critical precursor to the formation of O₃.

How do I know the level of the pollution problem in my country/community?
Many cities have implemented monitoring networks that continuously measure air pollutants as part of their air quality management systems. Many of them regularly report an Air Quality Index (AQI) that is easy to interpret, and often color-coded, to warn of dangerous levels of air pollution. The information is accessible through websites, newspapers and apps. Countries define their own indices based on their own air quality standards. Therefore, they are not comparable between countries and are designed for public information purposes.

The availability of air quality monitoring is unequal both globally and regionally. This is because high quality monitors are expensive, as is the cost of training people to run and maintain monitoring networks. Even in places with good monitoring, there are discrepancies. For example, in some parts of Europe, there are very dense monitoring networks, while in other parts the networks are less dense. In many developing countries across the world there is no official air pollution monitoring.

Investing in air quality monitoring is very important because the larger the networks are, the more information we can have for a city, region or country. This information can be invaluable for helping people understand what the air pollution levels are where they live and take action to reduce their exposure to harmful levels. It's also important for governments, to be able to make short and long-term planning decisions to reduce air pollution

In many places, private companies are developing lower-cost air quality monitors that people can install in their own homes. This is leading to networks of citizen scientists reporting on air quality and citizen led online air quality databases.

A number of international and civil society organizations, and private companies, also collect and report air quality information, often based on a combination of monitoring and satellite data. Where local information is unavailable, these can be useful resources to understand the air pollution problem in your city or country.
Is clean air a human right?
In at least 155 countries, a healthy environment is recognized as a constitutional right. Obligations related to clean air are implicit in a number of international human rights instruments, including the Universal Declaration of Human Rights and the International Covenant on Economic, Social and Cultural Rights.

In 2019, at the 40th session of the Human Rights Council, the right to breathe clean air was highlighted in a report by the Special Rapporteur for Human Rights and the Environment. The report highlights the seven steps that States must implement , to fulfil the right to breathe clean air.

What are the most harmful substances in the atmosphere?
The main air pollutants affecting health are fine particulate matter (PM2.5), ground-level ozone (O3) and nitrogen dioxide (NO₂).

Fine particulate matter of carbon, nitrogen, sulfur, heavy metals, etc. penetrate deep into the lungs and circulatory system. They cause damage to organs and tissues mechanically and toxically.

Ground-level ozone (O3) is produced in the atmosphere. Its effects are aggressive and affect the lungs, irritating them and causing discomfort when breathing.

Nitrogen dioxide (NO₂) also has a harmful effect on the lungs, and its high concentration causes secondary pollution.

The pollution level is measured in units of PM2.5. This means the presence of particulate matter smaller than 2.5 mm in diameter in the air - they are the most dangerous to health. Clean air has a value of PM2.5 = 0. A normal city gets 40-60 PM2.5. Values over 100 are already dangerous to health, and over 200 cause serious consequences. According to meteorological services, PM2.5 values can reach 600 in megacities.

Why is there not enough publicly available data on air quality?
In most large cities, pollution levels are measured with specialized stations. But these measurements do not always provide up-to-date data. Monitoring stations work only within 1-3 km and upload information within a few hours or a day. Their limited number is not able to cover all areas of the city, so the data on pollution is very inaccurate. And also after a few hours, the information may already be outdated.

At the moment there is no unified database where all the information about the state of the air is uploaded. Therefore, it is very difficult to track the level of pollution at the regional and global level.
