Cities are often markedly warmer than the countryside, and that's critical in a heat wave.

The National Aeronautics and Space Administration (NASA) has deployed a satellite instrument called Ecosystem Spaceborne Thermal Radiometer Experiment On Space Station (ECOSTRESS), which measures temperatures of the ground from space.</p>
<p>
The US space agency said that human actions and the materials utilised in the built-up environment cause cities to be significantly warmer than the surrounding countryside.</p>
<p>
According to the press note, the image covers around 12,350 square kilometres</p>
<p>
The space agency explained that the latest data suggests that city dwellers are experiencing considerably higher temperatures than the average temperatures reported for their regions.</p>
<p>
According to NASA, the recorded temperatures also show that even at night, the mercury remained high in several areas.</p>

In some cities, temperatures at night were reported to be as high as 39 degrees Celsius. Delhi, too, hovered around 35 degrees Celsius during the night, the press note said.</p>
<p>
The temperatures mentioned in the report were recorded on May 5 and released on May 13.</p>
<p>
NASA also informed that since mid-March, India and Pakistan have been engulfed in an unrelenting heatwave that has resulted in multiple deaths, fires, greater air pollution and low agriculture production.</p>
