Coordination and Data Management of the U.S Interagency Arctic Buoy Program (IABP)

Providing fundamental observations of sea ice, surface meteorology, and oceanography to improve weather forecast and understand Arctic climate

The U.S Interagency Arctic Buoy Program (IABP) strives to maintain a network of buoys with a spacing of less than 250 km, or more than 200 buoys spread across the Arctic Ocean. These buoys are essential for predicting weather and temperature anomalies, which rely on in-situ observations of surface meteorology and oceanography. Collected observations  are also used for Numerical Weather Prediction models to forecast weather and sea ice conditions, contribute to long-term atmospheric reanalysis data useful for multiple climate studies, validate satellite-derived estimates of sea ice motion, temperature, sea ice thickness, etc., among other uses. These observations provide the longest continuing record for the Arctic and have been one of the cornerstones for environmental forecasting and studies of climate and climate change.

About The IABP Database

Buoy data files are updated daily and made available individually via the links below. Values provided are confined to surface temperature, atmospheric temperature, and barometric pressure when these values are available. All buoy files contain at least a date and position. Buoys that are no longer reporting remain available on the main IABP data website:

Observing Arctic Sea Ice

April 6, 2022

Melinda A. Webster , Ignatius Rigor, and Nicholas C. Wright 

Our understanding of Arctic sea ice and its wide-ranging influence is deeply rooted in observation. Advancing technologies have profoundly improved our ability to observe Arctic sea ice, document its processes and properties, and describe atmosphere-ice-ocean interactions with unprecedented detail.  Yet, our progress toward better understanding the Arctic sea ice system is mired by the stark disparities between observations that tend to be siloed by method, scientific discipline, and application. This article presents a review and philosophical design for observing sea ice and accelerating our understanding of the Arctic sea ice system.
