Abstract

This work assesses the feasibility of using a single channel shortwave infrared (SWIR) approach to detect and chart sea ice in Hudson Bay using GOES-16 data as a proxy for overhead persistent infrared. While not traditionally exploited for sea ice remote sensing, the availability of near continuous shortwave infrared data streams over the Arctic from overhead persistent infrared (OPIR) satellites could provide an invaluable source of information regarding the changing Arctic climate. Traditionally used for the purpose of missile warning and strategic defense, characteristics of OPIR make it an attractive source for Arctic remote sensing as the temporal resolution can provide insight into ice edge melt and motion processes. Fundamentally, the classification algorithm discerns water/ice/clouds using a time-based algorithm as well as raw data processing enhancements. Demonstration of the temporal utility and sensitivity of GOES-16 SWIR to detect and discern water/ice/clouds provides a justification for exploring the utility of military OPIR sensors for civil and commercial applications. Products will be limited by seasonal solar presence due to their reliance on reflected energy and will have a spatial resolution constrained by the underlying data set. Potential users include the scientific community as well as emergency responders, the fishing, oil and gas, and transportation industries that are seeking to exploit changing conditions in the Arctic but require more accurate and timely ice charting products.
