A Decade of Sentinel-1 Scanning the Globe: How Much Flooding Have We Been Missing?
Key takeaway: Several global flood datasets already exist, but their long-term records rely primarily on optical remote sensing from satellites such as MODIS and Landsat. Yet the most severe floods often occur under thick cloud cover. The real question this study seeks to answer is not “How can we detect floods one more time?” but…

From Detecting Change to Assessing Risk: Satellite Remote Sensing for High-Mountain Hazards
On August 26, 2026, a cascading debris-flow disaster originating on the Nepal side of the China–Nepal border struck Gyirong Port in Xizang, China. Based on pre- and post-event high-resolution satellite imagery, seismic reports, and imagery transmitted from the affected area, an expert working group organized by China’s Ministry of Natural Resources preliminarily assessed that the…

Rising Peatland Fire Risk in Southeast Asia: How Satellite Monitoring Strengthens Early Warning and Transboundary Haze Prevention
Southern Southeast Asia has entered its traditional dry season. As hotter and drier conditions develop, fire and smoke signals are emerging in parts of Indonesia and the wider region, raising concerns about the risk of transboundary haze later in the season. As of July 26, 2026, Palangka Raya, the capital of Central Kalimantan, Indonesia, had…

Wildfire Smoke from Canada Crosses into the United States: How Satellite Data Supports Wildfire Monitoring and Environmental Management
In mid-July 2026, smoke from wildfires burning across central Canada continued spreading southeast across the U.S.-Canada border, pushing Detroit’s Air Quality Index to its highest reported level since monitoring began in 1999. Several cities were listed among the most polluted major cities in the world during this period. A watercraft sits in the Detroit River…
