Penelope Wagner is based at the Norwegian Ice Service in the Division for Forecasting in Tromsø. Penelope works on the validation, evaluation and assists with assimilation of remote sensing data products for operational use and to aid in sea ice monitoring and forecasts. Since 2006, she has been working with remote sensing applications to observe sea ice using optical, hyperspectral, scatterometer and passive microwave data for both planetary (Mars) and Earth Observation. She is currently focused on how the use of multi-polarisation and multi-frequency Synthetic Aperture Radar (SAR), and optical sensors can aid and support operational monitoring for sea ice characteristics including type (stage of development). Additionally, she has been involved in integrating stakeholder and end-user needs in order to improve the accuracy of sea ice products for navigational safety and for use in research as supplementary data products. She also assists in developing geospatial analysis tools. She is a participant on the EU Horizon 2020 research project, Arctic Search and Rescue (ARCSAR), and Work Package Leader for the Key Environmental monitoring for Polar Latitudes and European Readiness (KEPLER).
