The Importance of Definition (or, “It Depends on the Application”): Revisiting the Meaning of “Successful ‘Transition' and ‘Improvement'” Through Different Lenses
a) benchmarking, via the NASA Goddard Space Flight Center and Air Force Weather Agency (AFWA) -developed land verification toolkit (LVT), of a United States Army Corps of Engineers (USACE) Cold Regions Research and Engineering Laboratory (CRREL) -developed land surface model (LSM) “FASST” and
b) ensemble Kalman filter based assimilation of space-based (remotely sensed) soil moisture retrievals within the framework of the NASA Goddard Space Flight Center -developed Land Information System (LIS) towards informing of operational considerations and decisions.
We demonstrate how rather different interpretations of LSM and DA system development efficacy might be arrived at vis a vis differently posed objectives and differing metrics. We thus hope to inspire contemplation within the community of the importance of attention to how “better” is framed within the contexts of the examples presented as illustrations of a more general conception of technical improvement.
