a–d, The changes (building rooftops with RPVSPs scenarios minus building rooftops without RPVSPs scenarios) in simulated Tsurface during daytime (at 14:00 LT, top) and nighttime (at 02:00 LT, bottom) for RPVSPs 25% (a), RPVSPs 50% (b), RPVSPs 75% (c) and RPVSPs 100% (d) over an urban grid cell. The urban area of Kolkata is marked by the black line inside the box.
