Summary

The Sea Ice Prediction Network (SIPN) announces an open webinar entitled "Uncertainty in Satellite-Derived Sea Ice Extent Estimates."

This webinar is designed for the sea ice research community and others interested in information about the uncertainty in sea ice extent estimates from remotely-sensed data. While this is an open event, attendees should be aware that the discussions will largely be of a technical nature. The speaker will be Walt Meier, NASA Goddard Space Flight Center.

Walt Meier is a research scientist at the NASA Goddard Space Flight Center Cryospheric Sciences Laboratory. His research focuses on remote sensing of sea ice, development of new sea ice products and sea ice climate data records, and analyzing changes in the Arctic sea ice cover. He has been principal investigator on a project to create a sea ice climate data record.

Meier’s presentation will focus on uncertainty in sea ice extent estimates from remotely-sensed data. Arctic sea ice extent estimates from remote sensing data (e.g., passive microwave sensors like Advanced Microwave Scanning Radiometer-Earth Observing System [AMSR-E] and others) are widely used to project sea ice trends, initialize models, and evaluate model forecasts. As with all kinds of remote observations, this method of estimating sea ice extent has strengths and weaknesses that result in unique kinds of uncertainty. To date, however, little effort has been made to provide an uncertainty range of extent estimates from satellite data. Meier will discuss our current understanding of these issues and propose various methods of estimating extent uncertainty, with the aim of improving analyses of sea ice extent trends and variability. Time for participant questions will follow the presentation.

More details including registration instructions, will be announced closer to the event. The webinar will be archived and available online after the event.
