Last Week in Earth Observation: May 26, 2025

Forests on Fire, EO Summit + Why are Google and Microsoft building AI weather models?

Welcome to a new edition of ‘Last Week in Earth Observation’, containing a summary of major developments in EO from the last week and some exclusive analysis and insights from TerraWatch.

🗞️ Interesting Stuff: More News

This signals three potential shifts for EO satellite companies:
i) diversify revenue streams and expand internationally,
ii) accelerate adoption of EO in commercial use case, and
iii) push toward deeper partnerships or consolidation for survival.
It’s yet another reminder that government demand is not and will not be guaranteed. Long-term sustainability in EO will depend on building broader market traction and more resilient business models.

One Discussion Point

Exclusive analysis and insights from TerraWatch


Why are Google and Microsoft building AI weather models?

In the last few months, Google released GraphCast, a machine learning-based global weather forecasting model, and Microsoft followed with Aurora, its own AI weather models. Both claim faster, cheaper, and more accurate forecasts than traditional models.

I think the real story here is not about weather accuracy, and it is definitely not about replacing ECMWF or NOAA in the future.

This is really about weather becoming part of the cloud infrastructure, about turning forecasting into a cloud-native service that’s deeply embedded within their compute ecosystems. So, really the move has less to do with weather itself, and everything to do with their platform strategy.

Making Weather as the Sticky Layer

For sectors such as energy, insurance, agriculture, logistics and finance, weather is not just data, it is a key decision driver. If you can offer native, on-demand, customisable forecasts, users will start building their products and workflows around you: models, simulations, dashboards, alerts and triggers, aka a sticky service layer.

And this goes beyond just weather. The AI models they are building extend to air quality, wildfires, floods, and broader Earth system monitoring, expanding the strategic value even further across more use case.

So, instead of calling external weather APIs or downloading gridded files from public agencies, users will, in the future, be able to:

The big advantage? All of this takes place within their native environments using existing tools they are using BigQuery / Synapse / Redshift and their proprietary data pipelines. Once that happens, migrating away is not going to be inconvenient as it becomes expensive, time-consuming, and operationally disruptive.

Simply put, the goal is make weather become part of the glue that makes cloud platforms sticky i.e. a service that users build around, integrate with, and ultimately depend on for their business.

It follows the same logic that made maps (think Google Maps), payments (think Stripe) and cloud-native data warehousing (think Snowflake) part of the modern platforms: embed a critical service, make it programmable, and turn it into infrastructure.Once the service powers forecasts, decisions, or operational workflows, it’s no longer just a feature, it is foundational.

TL;DR: I think Google and Microsoft are trying to make weather foundational by turning it into a programmable infrastructure layer, that powers the horizontal layer of weather intelligence and climate services.

PS. Don't Forget NVIDIA

While Google and Microsoft are building the service layer for weather intelligence, NVIDIA is playing a different but equally critical role.

Through its high-performance GPUs, developer frameworks like Modulus, and its Earth-2 platform, NVIDIA is positioning itself as the compute and simulation backbone for next-generation weather and climate modeling. They are not offering forecasts they’re enabling them. Not competing with cloud providers, but powering them under the hood.

Forests on Fire

According to analysis published by the World Resources Institute, the tropics lost a record 6.7 million hectares of rainforest in 2024, an area nearly the size of Panama. While there was some good news with declines in Malaysia and Indonesia, this above figure is more than any other year in at least the last two decades, was driven mainly by fires.

Long-term satellite records like those from Landsat are a fundamental part of such analysis. Check out the article for more information on country-level trends and other factors that contributed to the deforestation.
