🛰️ Fun fact: MTG-S scans nearly 2,000 thermal infrared wavelengths every 30 minutes to build 3D atmospheric maps and speed up storm predictions.

The Meteosat Third Generation-Sounder (MTG-S) just captured its first hyperspectral images of temperature and humidity over Europe and northern Africa:

• Provides a new level of detail on atmospheric layers.

• Improves weather forecasting accuracy and lead time.

• Enhances air-quality monitoring across the region.

🌍🤖 How is AI helping us manage climate risk?

The *Resilience Revolution : is shifting us from just measuring climate risk to actively managing it:

• Earth Observation satellites : + *AI-powered weather models : give real-time, actionable insight.

• SAR satellites : “see” through clouds and at night for all-weather monitoring.

• AI models : generate hyperlocal forecasts in seconds, not hours.

• Helps governments, utilities, and communities prepare and respond before disasters hit.

🗺️ To understand the Middle East right now, you need context on Iran — here’s the visual story in 20 maps, charts, and infographics:

• Geography and demographics that shape Iran’s position.

• Nuclear program, oil economy, and missile arsenal at a glance.

• Alliances that have influenced the current conflict.

A few facts that often get missed:

• Iran is 80× larger than Israel.

• Its missile range covers the entire Middle East and beyond.

• One-fifth of global oil consumption passes through the Strait of Hormuz, which Iran borders.

• Sanctions once cut crude exports by over 85%, yet production has rebounded.

This is the background the headlines skip.

🛰️ Satellites show how Tibet’s tectonic collision reshapes the continent:

• New study using Copernicus Sentinel-1 radar and GNSS data finds the Tibetan Plateau is less rigid than thought.

• Faults like the Kunlun let the plateau’s interior flow east–west, stretching and collapsing under huge forces.

• Produces the highest-resolution maps yet of continental deformation.

• Helps refine seismic hazard models for the region.

🛰️ How can satellites reveal development needs hidden by national averages?

Researchers combined satellite imagery with machine learning to estimate Human Development Index scores for 61,530 municipalities worldwide:

• Over half the global population lives where local development differs from national averages.

• Fine-grained insights help target policy and aid more effectively.

• Shows the power of combining remote sensing with AI for global development.

🌍 Tracking air quality from space is getting sharper! EUMETSAT and Copernicus help Europe monitor pollution and greenhouse gases:

• CAMS uses satellite data to forecast air quality, track emissions, and inform policy.

• Covers nitrogen dioxide, methane, carbon dioxide, aerosols, and more.

• Fun fact: EUMETSAT data powers tools like the Methane Hotspot Explorer to locate emission sources worldwide.

Next up: Sentinel-4, Sentinel-5, and CO2M will deliver faster, more accurate atmospheric observations across Europe 🛰️

🎈 Fun fact: some stratospheric balloons have stayed aloft for 3 years straight!

High-Altitude Platform Stations (HAPS) fill the gap between drones and satellites for:
• Connectivity in remote areas
• Earth observation
• Disaster monitoring

What would you track from 20 km up? 🌍
