Subject: Public confusion regarding discrepancies in AQI readings across platforms
Respected Sir/Madam,
I am writing to draw your attention to a growing concern among the public regarding the noticeable discrepancies in Air Quality Index (AQI) readings displayed by the SAMEER App and various private air quality monitoring applications.
It has been frequently observed that at the same point in time, the SAMEER App may show an AQI reading of around 264 (indicating poor air quality), while several private applications report significantly lower values, such as 94 (indicating moderate air quality), and at times even the reverse. Such wide variations understandably lead to confusion and concern

among citizens trying to make informed decisions about their health and daily activities.
While it is understood that differences may arise due to varying methodologies, data sources, monitoring station coverage, averaging techniques, and calculation standards, the lack of clear communication on these differences is contributing to public uncertainty and mistrust.
In light of this, it is requested that the Commission for Air Quality Management (CAQM) take the initiative to:
*Clearly explain the reasons behind these discrepancies in AQI readings
*Publish simplified guidelines on how AQI is calculated across different platforms
*Clarify which sources or standards should be considered most reliable for public health decisions
*Enhance public awareness through official communication channels
A transparent and accessible explanation from CAQM would go a long way in building public confidence and ensuring that citizens can interpret air quality data correctly and responsibly.
Thank you for your attention to this important matter. I look forward to your response and to greater clarity for the general public.
Yours sincerely,
B S Vohra, Environment & Civic Activist, President, East Delhi RWAs Joint Front - Federation
