Recent data analysis and current atmospheric observations indicate that air quality in New Delhi is governed by pollutant-specific seasonal cycles rather than uniform trends.

近期的數據分析與目前的氣象觀測顯示，新德里的空氣品質受特定污染物的季節性週期影響，而非統一的趨勢。

The research conducted by Envirocatalysts, utilizing Central Pollution Control Board (CPCB) data from 2015, establishes that different pollutants exhibit distinct temporal trajectories. Particulate matter (PM2.5 and PM10) demonstrates a marked concentration during the winter period, specifically from October to February, whereas nitrogen dioxide (NO2) and ozone (O3) exhibit higher concentrations during the summer months. The peak for ozone typically occurs in May, a phenomenon attributed to the photochemical reaction of nitrogen oxides and oxygen under solar radiation. Conversely, the reduction of particulate matter during the mid-year period is attributed to meteorological dispersion and precipitation rather than a decrease in emission loads.

Envirocatalysts 利用 2015 年中央污染控制委員會 (CPCB) 的數據進行研究，確立了不同污染物呈現出截然不同的時間軌跡。懸浮微粒 (PM2.5 與 PM10) 在冬季（特別是 10 月至 2 月）顯示出明顯的濃度集中，而二氧化氮 (NO2) 與臭氧 (O3) 則在夏季月份濃度較高。臭氧的高峰通常發生在 5 月，此現象歸因於氮氧化物與氧氣在太陽輻射下的光化學反應。相反地，年中期間懸浮微粒的減少歸因於氣象擴散與降水，而非排放量減少。

Stakeholder positioning emphasizes the necessity of a granular approach to pollution mitigation. Sunil Dahiya of Envirocatalysts posits that the reliance on meteorological conditions for pollutant dispersal is insufficient, advocating for targeted interventions at the emission source. The distinction in pollutant origins is critical: PM2.5, CO, and NO2 are primarily derived from combustion processes in industry and transport, while PM10 is largely associated with crustal dust and construction activities.

利害關係人的立場強調了採取精細化污染緩解方法的必要性。Envirocatalysts 的 Sunil Dahiya 主張，依賴氣象條件來分散污染物是不夠的，提倡在排放源頭採取針對性干預。污染物來源的區分至關重要：PM2.5、CO 與 NO2 主要源自工業與運輸的燃燒過程，而 PM10 則大多與地殼塵埃及建築活動相關。

Recent empirical observations corroborate these patterns. A temporary transition to 'satisfactory' air quality (AQI 86) was recorded in May, facilitated by pluvial washout and wind-driven dispersion. During this interval, ozone emerged as the primary pollutant, aligning with the identified seasonal shift from particulate dominance in winter to gaseous dominance in the pre-monsoon phase. Forecasts indicate a regression to 'moderate' or 'poor' air quality categories as meteorological catalysts abate.

近期的經驗觀察證實了這些模式。5 月記錄到空氣品質暫時轉為「令人滿意」（AQI 86），這是由雨水沖刷與風力擴散促成的。在此期間，臭氧成為主要污染物，與已確定的季節性轉移一致——即從冬季的微粒主導轉向季風前階段的氣體主導。預測顯示，隨著氣象催化因素減弱，空氣品質將回落至「中等」或「不佳」類別。

Current air quality in New Delhi has seen a brief improvement due to weather conditions, though long-term data suggests a persistent need for pollutant-specific mitigation strategies.

新德里目前的空氣品質因天氣條件而有所短暫改善，但長期數據顯示，仍持續需要針對特定污染物的緩解策略。
