The DOE E3SM Model Version 2: Overview of the Physical Model and Initial Model Evaluation

Journal of Advances in Modeling Earth Systems, 2022
This work documents version two of the Department of Energy's Energy Exascale Earth System Model (E3SM). E3SMv2 is a significant evolution from its predecessor E3SMv1, resulting in a model that is nearly twice as fast and with a simulated climate that is

Evaluation of present-day extreme precipitation over the United States: an inter-comparison of convection and dynamic permitting configurations of E3SMv1

Environmental Research: Climate, 2023
Accurate simulation of the present-day characteristics of mean and extreme precipitation at regional scales remains a challenge for Earth system models, which is due in part to deficiencies in model physics such as convective parameterization (CP), and ...

A Weather-Driven Model for Predicting Infections of Grapevines by Sporangia of Plasmopara viticola

Frontiers in Plant Science, 2021
A mechanistic model was developed to predict secondary infections of Plasmopara viticola and their severity as influenced by environmental conditions; the model incorporates the processes of sporangia production and survival on downy mildew (DM) lesions,

Evaluating Models for Model-Based Debugging [PDF]

2008 23rd IEEE/ACM International Conference on Automated Software Engineering, 2008
Developing model-based automatic debugging strategies has been an active research area for several years, with the aim of locating defects in a program by utilising fully automated generation of a model of the program from its source code. We provide an overview of current techniques in model-based debugging and assess strengths and weaknesses of the ...

Development and Validation of a Mechanistic, Weather-Based Model for Predicting Puccinia graminis f. sp. tritici Infections and Stem Rust Progress in Wheat

Frontiers in Plant Science, 2022
Stem rust (or black rust) of wheat, caused by Puccinia graminis f. sp. tritici (Pgt), is a re-emerging, major threat to wheat production worldwide. Here, we retrieved, analyzed, and synthetized the available information about Pgt to develop a mechanistic,

Model Evaluation of the Stochastic Boolean Control Networks

IEEE Transactions on Automatic Control, 2021
This article investigates the model evaluation problem for the stochastic Boolean control networks (SBCNs). First, an algebraic expression of the SBCN is obtained based on the semitensor product method, and a straightforward approach is then proposed to ...
