21OESS Value Tree Assessment of Low Earth Orbit Observations for the Dynamic Arctic Region

In the evolving Earth-system climate, the polar regions are experiencing the greatest rates of change. Changes in the physical environment pose challenges to Arctic communities as they seek to adapt to new climate realities while also providing opportunities to economic sectors previously restricted by cold, harsh, and ice-dominated conditions. NOAA is in the process of formulating the next generation of low-earth observation (LEO) sensors after the Joint Polar Satellite System (JPSS). LEO satellites provide the primary orbital geometry to serve the Arctic region. While numerous studies have explored value chains linking earth observations to societal benefit, none have looked specifically at the LEO capabilities NOAA typically operates as applied to the rapidly-changing Arctic region.

This poster presents work undertaken by NOAA’s Office of Low Earth Orbit (LEO) Observations to build a value tree linking Arctic societal benefit areas (SBAs) to types of LEO observations. This work seeks to demonstrate which sensor types will provide the greatest impact to the dynamic commercial, cultural, and resource environment in the Arctic region over the next few decades. The value tree assessment will be shaped by principles and frameworks established in other published work along with using internal NOAA data and user engagement activities. Conclusions from this effort will help inform requirements for next-generation disaggregated LEO satellite capabilities.
