Net Radiation

Bounding the role of surface radiation in Arctic climate with in situ observations

The IASOA Radiation working group convened in Vancouver, May 2013, to begin to identify key Arctic atmospheric radiation questions.


Radiation measurements are a crucial component of the surface energy balance and provide evidence of the impacts of clouds, aerosols, and cryospheric changes.  Seven of the IASOA observatories are current or candidate Baseline Surface Radiation Network (BSRN) sites.  These sites must pass the highest quality control to assure the accuracy.  Most IASOA radiation datasets are available through our Data Access Portal, some are soon to be available.  Visit Data->Data-at-a-Glance to access this data.

IASOA experts have looked extensively at issues for successful year-round radiation data collection in the Arctic.
