Cubbon Park: Air Quality & Environmental Report (Feb - June 2025)
(Data collected from KR Circle Gate, Lotus Pond, Maharaja Statue, Corporation Gate, and State Central Library)
Overview
This report provides key weekly trends in air quality and environmental factors in Cubbon Park, Bengaluru, analyzing IoT sensor data from five locations over the period of February to June 2025.
Air Quality Index (AQI)
* Pattern: Weekly average AQI generally fluctuated between 80 and 120.
* Indication: This range suggests moderate to unhealthy air quality for sensitive groups.
* Trend: Higher variability and some of the highest AQI readings were observed in the drier, pre-summer months (February and early March).
* Insight: Urban pollution sources like traffic or construction likely influence the persistent moderate-to-unhealthy AQI.
Particulate Matter (PM2.5 & PM10)
PM2.5
* Pattern: Weekly average levels typically ranged between 30 and 60 \mu~g/m3.
* Trend: Higher levels were often present during the drier months (February and March), with values stabilizing or slightly lower as pre-monsoon and early monsoon periods began.
* Insight: Fine particulate matter, likely from vehicle emissions or industrial activities, affects the park's air.
PM10
* Pattern: Weekly average levels generally ranged between 40 and 80 \mu~g/m3.
* Trend: Higher values were noticeable in drier months (February and March), with some moderation during pre-monsoon and early monsoon periods.
* Insight: Coarse particulate matter, likely from road dust or construction, consistently impacts air quality.
Environmental Factors
Humidity
* Pattern: Weekly average humidity levels show a gradual increase.
* Trend: A clear increasing trend was observed from drier months (February and March) towards pre-monsoon (April-May) and early monsoon (June) seasons.
* Insight: This is typical for Bengaluru's climate, and rising humidity can influence pollutant dispersion.
Pressure
* Pattern: Weekly average pressure remained relatively stable, generally hovering between 800 and 950 units.
* Trend: Pressure levels remained consistent across all observed seasons.
* Insight: Stable pressure indicates typical atmospheric conditions and the absence of major extreme weather events.
Temperature
* Pattern: Weekly average temperatures showed an increasing trend from February.
* Trend: Temperatures peaked during Bengaluru's summer months (April-May) and then slightly moderated or stabilized in June with monsoon influences.
* Insight: This seasonal pattern is characteristic of Bengaluru's hot summer, and higher temperatures can influence pollutant formation
