Figure 3. Diagrams showing that Aakash/CUPI-G ground-based observation network allows us to track the movement of plumes from Punjab to Delhi. Four days of high PM2.5 in Delhi-NCR are shown in 2022 (top row) and 2023 (bottom row). The CRB effect always elevates the daily mean PM2.5 concentration (red circles) in South Punjab, while the direct effect of CRB rarely reaches to Delhi-NCR. The CUPI-Gs recorded PM2.5 continuously, even under hazy and cloudy conditions when satellites cannot detect CRB or related information.
