India is currently experiencing a lengthy heatwave, with temperature levels in various cities throughout the country topping 42 ° C(108 ° F). This comes just weeks after India tape-recorded its hottest March since the countrys meteorological department started its records over 120 years back. The image above, produced using data from the Copernicus Sentinel-3 objective, reveals the land surface temperature across the majority of the country.
According to the India Meteorological Department, maximum air temperatures reached 43-46 ° C( 109-115 ° F) over many parts of Rajasthan, Vidarbha, Madhya Pradesh, and East Uttar Pradesh; in lots of parts over Gujarat, interior Odisha; and in some parts of Madhya Maharashtra on April 28, 2022. Weather condition forecasters alerted that heatwave conditions are expected to continue through May 2.
Experts at the Indian Institute of Technologys Water and Climate Lab specified that, recently, the number of Indian states struck by heatwaves has increased, as extreme temperatures end up being more frequent.
Owing to the absence of cloud cover on April 29 (10:30 regional time), the Sentinel-3 spacecraft was able to acquire a precise measurement of the land surface temperature of the ground, which exceeded 60 ° C( 140 ° F)in several areas. The data shows that surface area temperature in Jaipur and Ahmedabad reached 47 ° C(117 ° F), while the most popular temperatures tape-recorded are southeast and southwest of Ahmedabad (visible in crimson) with optimal land surface area temperature levels of around 65 ° C (149 ° F).
The map was created by utilizing the objectives Sea and Land Surface Temperature Radiometer instrument. While weather forecasts utilize anticipated air temperature levels, this satellite instrument measures the real quantity of energy radiating from Earth. The map reveals the real temperature of the lands surface visualized here, which is usually significantly hotter than air temperature levels.
Sentinel-3 can monitor wildfires, map the way the land is used, provide indices of plant life state, along with step the temperature level, color, and height of the sea surface.
