In this study, we propose a solution to estimating system responses to external forcings or perturbations. We utilize the Fluctuation-Dissipation Theorem (FDT) from statistical physics to extract knowledge using an AI model that can rapidly produce scenarios for different external forcings by leveraging FDT and analyzing a large dataset from Earth System Models. Our model, AiBEDO, accurately captures the complex effects of radiation perturbations on global and regional surface climate, enabling faster exploration of the impacts of spatially-heterogenous climate forcings. We demonstrate its effectiveness by applying AiBEDO to Marine Cloud Brightening, a climate intervention technique, aiming to optimize cloud brightening patterns for regional climate targets and prevent climate tipping points. Our approach has broader applicability to other scientific disciplines with computationally demanding simulation models. Source code of AiBEDO framework is made available at https://github.com/kramea/cikm_aibedo. A sample dataset is made available at https://doi.org/10.5281/zenodo.7597027.

Scientists often use specific data analysis and presentation methods familiar within their domain. But does high familiarity drive better analytical judgment? This question is especially relevant when familiar methods themselves can have shortcomings: many visualizations used conventionally for scientific data analysis and presentation do not follow established best practices. This necessitates new methods that might be unfamiliar yet prove to be more effective. But there is little empirical understanding of the relationships between scientists' subjective impressions about familiar and unfamiliar visualizations and objective measures of their visual analytic judgments. To address this gap and to study these factors, we focus on visualizations used for comparison of climate model performance. We report on a comprehensive survey-based user study with 47 climate scientists and present an analysis of: i) relationships among scientists' familiarity, their perceived levels of comfort, confidence, accuracy, and objective measures of accuracy, and ii) relationships among domain experience, visualization familiarity, and post-study preference.

The queue size distribution and average waiting time for a time-shared system using round-robin scheduling, with and without overhead, are derived.Priorities are assigned to incoming users based on a decreasing function of program length.Using this priority assignment, a cost analysis is made that shows the effects of changing the system parametets and determines the optimum quantum length.The input rate and the quantum length that will saturate the system are also determined.
