Earth Science Modeling &
Observing System Support
Specialized expertise in Earth system modeling, coupled atmosphere–ocean–ice systems, and OSSE-based evaluation for NASA Earth science mission programs.
Supporting NASA's Earth Science Division
Earthwise provides embedded scientific and technical support to NASA Earth science programs, delivering expertise in Earth system modeling (including coupled atmosphere–ocean–ice systems and data assimilation) and OSSE-based evaluation of current and future observing systems.
We support mission workflows in observation integration, model performance assessment, uncertainty analysis, and AI-enabled scientific workflows aligned with mission science and system development. Our work aligns with programs within the Earth Science Division and GMAO, helping mission teams improve model fidelity and quantify the value of observations.
How We Support NASA Programs
Earthwise delivers surge and specialty technical support to NASA programs and NASA-supporting primes.
Rapid Integration Into Modeling Workflows
Embedded directly into mission teams and modeling workflows with minimal ramp-up time.
DA, OSSEs & System Evaluation
Support for high-priority tasks in data assimilation, OSSEs, and comprehensive system evaluation.
Flexible Engagement
Adaptable across proposal support, task orders, and sustained program efforts.
Capture-to-Execution Continuity
Seamless continuity from capture through post-award execution — no handoff gaps.
