Using Space-Tech to Combat Extreme Heat and Climate Change
Temperatures are soaring. Well past forty deGrees Celsius. That kind of heat is tearing up daily life across cities right now. And somewhere in the background, an emerging space-tech start-up is trying to use satellite data to help people deal with this dangerous heat this summer.
Satleo Labs is one of those players. They built a platform, recently launched in Ahmedabad, which is currently hammered by this season's severe heat. How they do it? They use satellite thermal technology mixed with AI analytics. It maps out those urban heat hotspots and spits out three-day forecasts. The accuracy is pretty good, around two or three deGrees Celsius.
They teamed up with the Ahmedabad Municipal Corporation, or AMC. The goal was to give citizens specific heat advisories, right where they are. You scan a QR code, and you get location-specific heat warnings. This really helps the folks who are most exposed—the outdoor gig workers, the delivery drivers, the cab drivers. They spend so much time outside, they feel the heat the most.
Shravan Bhati, the co-founder and CEO, said they wanted to combine space technology with climate planning to get a better response to this extreme heat. He pointed out the core problem: temperatures keep rising, cities are changing fast. And they just don't have the high-resolution, hyperlocal climate data they need.
The weather department throws out color-coded alerts for whole regions based on the highs and lows. But that’s just averages. You know how it is, temperatures swing wildly inside a city. Depending on where the Green spaces are, the amount of concrete, how dense the population is—it all changes things.
That’s where the team stepped in. They bridged that gap using thermal intelligence from low-earth orbit. They use open-source thermal datasets from satellites like MODIS and Landsat.
But those satellites? Their resolution is kind of coarse for getting super precise city-level details. So they had to build their own stuff. Proprietary AI algorithms to crank up that low-resolution thermal imagery. Turning it into detailed thermal intelligence layers.
They fed historical data, collected over five or ten years, into these models. Then they layered on real-time satellite observations. This builds predictive models. They can forecast where the heat hotspots will be and what the hyperlocal temperature patterns will look like for the next three or four days. They did this for Ahmedabad, and Tumkur in Karnataka. And they plan to push it to other cities. They’re even planning to launch their own thermal satellite soon.
This isn't just for comfort. The platform shares these heat-risk insights with government clinics and frontline health workers. It helps them prepare for heat-related illnesses. If an area is flagged for extreme heat, officials can move fast. Set up temporary clinics. Deploy extra medical staff. Prepare for heatstroke cases.
India is having this extreme heat again this summer. Large swathes of the country are being swept by intense heatwaves. Western states like Gujarat and Rajasthan are really taking the hit. Temperatures settle way above forty-five deGrees Celsius for days. Barmer hit 48.3°C at its peak.
The nights are getting warmer too. The weather department is warning about minimum temperatures being above normal levels in May. Scientists are clear now. Climate change has made these heatwaves more intense. More frequent. Longer. It’s hitting people and the economy hard.
With accurate temperature intelligence becoming this crucial for everything, space-tech startups are jumping in. India has seen a huge surge in space start-ups since the government opened up the sector for private money back in 2020.
The idea is that a satellite-based platform is way better than relying on expensive IoT devices or drone surveys for monitoring temperatures. Those methods cost a lot of money, several lakh rupees. This satellite approach offers a scalable alternative. It spots urban heat islands. It tracks where Greenhouse gases are hot spots. It helps city authorities react better to dangerous heat.
