The PacIOOS Wave Run-Up Forecast is a tool to predict the potential occurrence of high sea levels and wave inundation impacting the shorelines of Kwajalein. The forecast is updated hourly (about 15 minutes after the hour) and dates and times are shown in local time.
IOOS Modeling Community of Practice Models and Products
IOOS® data comes from a variety of instruments that are part of the nationwide observing system, including buoys, high frequency radar systems, water level sensors and gliders. Understanding the current and future state of our Nation’s coasts, oceans, and Great Lakes from these disparate and complex data sets is a challenge.
The IOOS® Regional Associations, academic, industry, and local and state government partners use models and tailored model products to understand and communicate current marine conditions, and forecast future marine conditions. Multiple user focused applications and products are often developed from one model, making the IOOS® Modeling Community of Practice model portfolio efficient and specifically tailored to stakeholder needs in their respective regions. IOOS® delivers and disseminates these models, forecasts, and products so that decision-makers can take action to improve safety, enhance the economy, and protect the environment.
Often, models developed by IOOS® partners are transitioned to NOAA for operational use; these are not included in the IOOS® modeling catalog, but are included in NOAA’s Operational Forecast Systems and Harmful Algal Bloom (HAB) forecasts. Additional model outputs from IOOS® partners can also be visualized in the IOOS® Model Viewer.
WHY USE MODELS?
IOOS uses models to understand current marine conditions, and forecast and predict future marine conditions.
Data Models organize and standardize data elements to understand how they relate to one another and to ocean, coastal, and Great Lakes properties
Model Applications translate and visualize modeling outputs to make data easier to see and understand.
