A Remote Sensing Solution for Nitrous Oxide: The Greenhouse Gas We Need to See Better

A Remote Sensing Solution for Nitrous Oxide: The Greenhouse Gas We Need to See Better

When we talk about greenhouse gases and climate change, carbon dioxide (CO2) and methane (CH4) usually receive most of the attention. Yet another gas, nitrous oxide (N2O), quietly plays an important role in our changing climate. Commonly known as “laughing gas”, N2O is a powerful greenhouse gas with nearly 273 times the warming potential of …[Read More]

Next-Gen Computing in Geosciences: High-Performance Computing, AI, and Quantum Frontiers

The Earth is an intricately coupled system, and simulating its behavior (from volcanic eruptions to global climate shifts) requires immense computational brute force. For decades, computers have been the quiet backbone of geosciences. Today, however, we stand at a major inflection point. High-Performance Computing (HPC) is pushing the boundaries of high-resolution simulations, while emerging technologies …[Read More]

Meet the Snow Dunes of Antarctica

Meet the Snow Dunes of Antarctica

By Marine Poizat, PostDoc at the Geological Survey of Finland. Email: marine.poizat@gtk.fi, website: https://www.gtk.fi/en/experts/poizat-marine/. Antarctica has dunes. And they are made of snow. When people think of deserts, they usually picture vast expanses of sand beneath a blazing sun. Yet Antarctica is also a desert, receiving remarkably little precipitation, especially inland. And like other deserts, …[Read More]

Genesis: One Satellite to Bring Four Geodetic Techniques Together

Genesis: One Satellite to Bring Four Geodetic Techniques Together

What if we brought all four major space-geodetic techniques together on a single spacecraft for the first time? ESA’s Genesis mission, expected to launch in 2028, will do just that, combining Global Navigation Satellite System (GNSS), Satellite Laser Ranging (SLR), DORIS and Very Long Baseline Interferometry (VLBI) on one carefully calibrated platform. Well before launch, …[Read More]

An archipelago as a natural laboratory: Pioneering ocean monitoring network in the Canary Islands

An archipelago as a natural laboratory: Pioneering ocean monitoring network in the Canary Islands

The Canary Islands are often shown as a group of small dots in the vast Atlantic Ocean. However, across only a few tens of kilometres, their surrounding waters can shift from sheltered coastal bays and energetic inter-island channels to the open subtropical ocean. This strong environmental contrast makes the archipelago an ideal natural laboratory for …[Read More]

The Breath of Forests, Cities, and Everything in Between: Eva Pfannerstill and the Air We Cannot See

The Breath of Forests, Cities, and Everything in Between: Eva Pfannerstill and the Air We Cannot See

There is a slow-moving silver shape drifting over the forests and cities of North Rhine-Westphalia. From the ground, it looks almost ceremonial — a Zeppelin NT gliding through the air as though time had reversed by a century. Inside, sensors are humming. And Eva Pfannerstill is watching the data appear. She is not there to …[Read More]
