Over the past several days, southern Thailand has faced catastrophic, long-duration rainfall, including what local authorities have called a “300-year event” in Hat Yai. As seen in the video attached, our microwave sounders repeatedly scanned the stalled tropical low over the region, cutting through cloud tops to reveal moisture structure and embedded convection driving the flooding rains. Fueled by this data, our 48-hour FOCUS probabilistic precipitation forecasts depicted a slow-moving system with elevated probabilities of persistent heavy rain over southern Thailand, capturing the risk of prolonged accumulation rather than a single short-lived burst.

The last of the NASA TROPICS satellites will deorbit this week, capping a mission that has collected over 11 billion high-resolution, high-revisit microwave atmospheric temperature+moisture sounding observations, more than all of the US and European operational polar-orbiting microwave sounders combined over the course of the mission (see accompanying plot). Thanks to an amazing team comprising government labs, universities, and private industry, the TROPICS mission achieved all of its baseline mission objectives and demonstrated the value of small-satellite microwave sounding data for tropical cyclone forecasting. Building on this foundation, the microwave sounding satellite constellation currently being deployed by Tomorrow.io (nine satellites and counting) based on TROPICS technology is demonstrating improved calibration and radiometric performance and significantly better forecasting impact than TROPICS, and is achieving this on a global scale. The next challenges to address are the inclusion of frequencies lower than 90-GHz for better sounding performance in clouds, larger apertures for better resolution, polarization diversity for better sensitivity to rain and ocean surface properties, and cognitive sensing to optimize observing resources for a given application - these are all possible on small satellites, and we are grateful for NASA ESTO funding to demonstrate these new technologies on a high-altitude ballon flight in the next 18 months. Stay tuned for more updates.

In the middle of an active storm season in the Philippines, the National Irrigation Administration (NIA) needed timely, accurate weather intelligence to protect critical agriculture and water infrastructure. Our Met team delivered. Forecasts from Tomorrow.io have been supporting the Philippine Ministry of Agriculture with actionable insights, helping local agencies prepare for storms like Tropical Depression Verbena before they make landfall. The impact? Recognized on the front page of NIA’s official report and featured during a multi-agency collaboration with leaders from across the government. Shoutout to the incredible Tomorrow.io team behind the scenes, making this happen. This is weather intelligence in action, supporting real-world decisions that safeguard lives, livelihoods, and resources.

This Thanksgiving, we’re especially grateful for the people that turn weather intelligence into real-world impact: our customers. You’ve challenged us to go faster. Trusted us with critical decisions. And partnered with us to solve real-world problems. Your collaboration inspires everything we do, from advancing our technology to expanding the real-world impact we can deliver together. From all of us at Tomorrow.io, Happy Thanksgiving! #Thanksgiving

What if you could see nearly the entire planet’s weather, every single hour? That will soon be the new reality. Including our newest satellites, here is the first global six-hour composite scans from our constellation, and the view is stunning. It’s not just the rainbow-bright temperature patterns. It’s what this level of coverage unlocks for you. For the first time, we’re capturing an unprecedented share of Earth in a single 6 hourly window, giving forecasters, emergency managers, aviation teams, and weather-sensitive industries faster, clearer, and more continuous weather intelligence than ever before. And here’s the exciting part: The white gaps you see in the image are shrinking with every satellite we launch. Soon, the world will be fully colored by our satellites alone, a continuously updated map with hourly refresh rates. When combined with government satellites, this will result in new microwave data every hour. That means faster decisions. Earlier warnings. More resilience.

Winter is almost here, which means ski trips, fresh snow, and long days outdoors. But there is one winter question most people still get wrong: Can you get sunburned in winter? Many are surprised to learn that snow can reflect up to 80 percent of UV rays, and higher elevations can increase UV exposure by 40 percent. That puts skiers, snowboarders, hikers, and even casual adventurers at higher risk than they expect. Cold weather can feel safe, but the UV impact is real. Swipe through for the full myth bust and simple ways to stay protected this winter. What other winter weather myths should we break next? #weathermyths

Can you guess the location from space? 🛰️🌍 Our newest satellites, Tomorrow-R1 S8 and S9, just delivered their first Earth scans, and they’re incredible. Think you can name both locations? Drop your guesses in the comments 👇 (Bragging rights to the first person who gets them right.)

Faster, more accurate, more local forecasts. That is what you get when you can see inside the atmosphere. Most satellites watch the tops of clouds. Helpful, not enough. It’s like trying to diagnose a patient by only looking at the skin. Tomorrow.io’s microwave sounders work like an MRI for the atmosphere, scanning through clouds to capture the hidden drivers of weather: humidity, temperature, and pressure profiles. Those internal views power earlier alerts, tighter ETAs, and safer windows for operations that cannot afford surprises. Airlines, logistics, and governments are turning this into real resilience on the ground and in the air. Better predictions require better observations. Not just more data, the right data. That is what we are putting on orbit with every satellite we launch. Where would seeing through clouds change your decisions first?

Last week, a F3 tornado tore through Paraná, part of a fast-moving line of storms in southern Brazil. Tomorrow.io's satellites captured what was happening: not just above the clouds, but inside them. While NOAA’s GOES-19 infrared imagery showed the storm’s towering cloud tops, a sign of severe weather, Tomorrow.io’s microwave sounders revealed what infrared alone couldn’t: the energy still pulsing within the storm. By seeing through thick ice clouds, our sensors exposed the storm’s internal structure, pinpointing where the most dangerous activity was still brewing. Together, the two views told a fuller story: confirming the atmosphere over southern Brazil was still unstable and capable of producing more severe weather. Infrared shows the surface. Microwave shows the soul. Together, they helped us understand what’s happening now and what could happen next. Learn more about our space mission: https://okt.to/JUhZGj

At Smart City Expo World Congress 2025 in Barcelona (Nov 4 to 6), we teamed up with Microsoft Azure to show how weather-aware AI turns forecasts into actions for city operations. When weather is built into your workflows, you get earlier warnings, clearer ETAs, fewer disruptions, and safer streets across mobility, flooding, power, and emergency response. With Tomorrow.io on Azure, you deploy faster, integrate securely, and scale across departments. Thanks to everyone who stopped by, and to our partners at Microsoft Azure for the collaboration! #SmartCityExpo #MicrosoftAzure #AI #UrbanResilience
