Typical Earth system models involve coupled model components in high-performance computing (HPC) environments. In the last few years, several frameworks have been developed for HPC applications. Two of them are component-based frameworks: the Earth System Modeling Framework (ESMF) defining a component interface for Earth system models and the Common Component Architecture (CCA) defining a gener...

Typical earth system models involve coupled model components in high performance computing (HPC) environments. There are two emerging component-based frameworks for developing HPC applications. The Earth System Modeling Framework (ESMF), funded by NASA Earth System Technology Office (ESTO) Computational Technologies (CT) Project, defines a domain specific component interface for earth system mo...

The Earth System Prediction Suite (ESPS) is a collection of flagship U.S. weather and climate models and model components that are being instrumented to conform to interoperability conventions, documented to follow metadata standards, and made available either under open source terms or to credentialed users. The ESPS represents a culmination of efforts to create a common Earth system model arc...

This paper discusses some of the challenges of providing systems management to BT’s operational support systems (OSS). As the OSS evolve to exploit the three-tier distributed architecture, the provision of successful systems management solutions must overcome many problems, including those of scale, scope, functionality, integration, rate of change, and the relative immaturity of available solu...

6 The GEOS-Chem global chemical transport model (CTM), used by a large atmospheric chemistry 7 research community, has been re-engineered to also serve as an atmospheric chemistry module for Earth 8 System Models (ESMs). This was done using an Earth System Modeling Framework (ESMF) interface 9 that operates independently of the GEOS-Chem scientific code, permitting the exact same GEOS-Chem 10 c...

Introduction: A team of NRL scientists from the Marine Meteorology and Oceanography Divisions has successfully transformed the one-way air–ocean Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS®*) into a six-way fully coupled air–ocean– wave weather and marine forecasting system. This was accomplished using the state-of-the-art Earth System Modeling Framework (ESMF), making COAMPS t...

Simultaneous state and parameter estimation based actuator fault detection and diagnosis (FDD) for single-rotor unmanned helicopters (UHs) is investigated in this paper. A literature review of actuator FDD for UHs is given firstly. Based on actuator healthy coefficients (AHCs), which are introduced to represent actuator faults, a combined dynamic model is established with the augmented state co...

This was done using an Earth System Modeling Framework (ESMF) interface that operates independently of the GEOSChem scientific code, permitting the exact same GEOSChem code to be use...

Actuator failure detection method based on a new Adaptive Extended Set-Membership Filter (AESMF) is proposed for Rotorcraft Unmanned Aerial Vehicle (RUAV). The AEMSF proposed in this paper is based on MIT method to optimize the set boundaries of process noises which may be incorrect in modeling or time-variant in operation; estimation stability and boundaries accuracy can be improved compared t...

Abstract. Two-way model coupling is important for representing the mutual interactions and feedbacks between atmosphere ocean dynamics. This work presents development of two-way coupled system ICONGETM, consisting ICON GETM. ICONGETM built on latest NUOPC software with flexible data exchange conservative interpolation via ESMF grids. With providing a state-of-the-art kernel numerical weather pr...
