Metocean-stats v1.2: An open-source framework for reproducible and actionable metocean data analysis

Metocean analyses are fundamental to offshore and coastal engineering, maritime operations, and renewable energy development, where reliable estimates of winds, waves, currents, sea level, and related variables are required for structural design, safety assessment, and operationa...

Feasibility Study of an Ultra-Low-Cost 3D-Printed Wave Buoy for Water Wave Measurement

Abstract This paper presents a feasibility study of an ultra-low-cost wave buoy for measuring water waves, built from a 3D-printed hull and an off-the-shelf data logger with an integrated MEMS inertial measurement unit. The buoy records continuously and carries no telemetry, whic...

Case Study: Effectively Communicating Modeling Uncertainty to Communities Affected by Cryospheric Hazards – A Look at Interdisciplinary Collaboration Regarding Mendenhall Glacier Lake Outburst Floods in Juneau, Alaska

Cryospheric hazards are natural phenomena that are highly sensitive to climate change impacts and can have devastating impacts on surrounding communities. The rate of glacial change and loss under climate change is unprecedented and can result in more severe glacial hazards globa...

Leveraging JEDI for atmospheric composition: a unified framework for evaluating observations and model forecasts

Accurate evaluation of both observations and forecasts is essential for advancing atmospheric composition research and improving operational prediction. Traditionally, this has relied on separate workflows with product-specific preprocessing, often limiting reproducibility and cr...

Estimating the Contribution of Traction Sanding to Observed PM10 Concentrations Using Mass Balance Arguments

<title>Abstract</title> PM ₁₀ concentrations in many countries in Europe are above or close to the limit values set out by the European commission for 2030. This includes both the daily mean and annual mean limit values of 45 µg/m ³ and 20 µg/m ³...

Measuring Ocean Surface Waves

Abstract Propagating waves on the ocean surface can be represented as a stochastic process whose statistics are characterized by a spectrum. This paper reviews methods for measuring the wave spectrum and related quantities. Observations begin by sensing fluid dynamical properties...
