Ash particles detected in the tropical lower stratosphere
We report here on measurements of relatively large (up to ≃5‐μm maximum dimension) particles detected in the tropical western Pacific lower stratosphere. The particles were...- publication PDF

Annual cycle in upper-ocean heat content and the global energy budget
As a major component of Earth's energy budget, ocean heat content (OHC) plays a vital role in buffering climate change. The annual cycle is the most prominent change in OHC but...- publication PDF
