Arctic Observation and Reanalysis Integrated System

The Arctic Observation and Reanalysis Integrated System is a merged database containing a suite of satellite, reanalysis, and in situ products. The products are utilized to construct a comprehensive dataset for the community to study multiple, and often complex, processes and interactions over the arctic region. With the dramatic decline in sea ice and snow extent in previous years it is essential to characterize the surface energy budget to gain a better understanding of how Arctic amplification of temperature may manifest in the future.
 
Satellite and reanalysis products are matched together in the integrated product using a common spatial resolution of 2.5°×2.5° and monthly averaging timescale. Primary variables include state-of-the art satellite retrieved cloud properties, radiation fluxes (top and bottom of atmosphere), surface precipitation rates, and snow and sea ice extents. Corresponding quantities are also provided from several reanalysis products.
 
The dataset is geared for scientific inquiry, product validation, and assessment of the radiation and moisture budgets in the Arctic.The majority of the data products used to construct this integrated dataset have been developed and published in peer-review journals. We encourage users of this data to familiarize themselves with pertinent documentation provided by each data product contained here. Below is a short list of the merged highlighted products.
