🌞 How does surface ozone (O₃) vary across India, and what roles do its precursors (VOCs, NOₓ, CO, HCHO) play?

We investigated the spatio-temporal variability of surface O₃ across India, using widely accepted precursor indicators like the HCHO/NOₓ ratio to classify O₃ formation regimes. We also explored the NO/NO₂ ratio to gain insights into the delicate balance between O₃ production and destruction. 🌤️

🔍 Key Findings:
1️⃣ Positive O₃ trends were observed across most of India — except in central Indo-Gangetic Plain (IGP).
2️⃣ VOC-limited regimes dominate, meaning O₃ formation is more sensitive to VOCs than NOₓ.
3️⃣ In the IGP, increasing NO/NO₂ ratios suggest reduced surface O₃ due to enhanced titration, despite high precursor loads.

📊 These results help decode the complex interplay of emissions and chemistry driving air quality over India — crucial for crafting effective mitigation strategies.

🌞 How is solar energy over India changing during satellite era? 🌏 

 We've been diving deep into understanding the changing dynamics of solar irradiance across India. 🌤️ Here are some key questions:

1️⃣ How has solar irradiance over India changed in recent decades based on satellite observations? 🛰️

2️⃣ What are the relative contributions of aerosols 🏭 and clouds ☁️ in driving the observed trends in solar irradiance over India during the satellite era?

3️⃣ How do changes in solar radiation impact India's solar energy potential ⚡, especially considering land constraints 🌾 and the roles of aerosols and clouds?
