Background

The overarching aim of this research is to understand and characterize relevant mechanisms and underlying processes that are key in current and future sea level change. Our goal necessitates an integrated approach which uses available the current and projected sea level change using NASA’s multi-satellite observations, modeling and climate system assimilation capabilities. Our interdisciplinary team consists of modelers and remote sensing experts in the fields of ocean, atmosphere, hydrology and cryosphere sciences, that is uniquely suited to contribute to this important question and the sea level change team.

Expected Significance

Our work builds on previous research efforts sponsored by NASA (including past NASA Sea Level Change Teams) and are primarily based on NASA observations and models, yet our research will benefit the larger sea level and climate research communities. The work also addresses the broader needs of stakeholders and others affected by sea level by investigating prognostic forecasts on seasonal and 21st century timescales.

Our team provides datasets to the N-SLCT portal; for example, the global sea level dataset from altimetry, which we can immediately revise and update without waiting for external groups to address reprocessing issues on their time frame. This strength applies to all the observational or modeling datasets that we will share with the N-SLCT, and given the importance of these dataset or models for sea level research, it is important that the N-SLCT has members cognizant of any issues that require special attention when dataset are used, assimilated or interpreted.
