“…In this study, 20 trials in various atmospheric stability conditions are selected and the meteorological variables are taken from an analysis of meteorological and micro-meteorological observations in Yee and Biltoft (2004) (Table 1). It is noted that the errors related to meteorological data can affect the accuracy of the source term estimation (Zhang et al, 2014(Zhang et al, , 2015, although this error is not considered in this study. In each trial, the gas was continuously released for ≈ 15 min, during which concentration measurements were made.…”

“…The probabilistic category treats source parameters as random variables associated with the probability distribution. This includes the Bayesian estimation theory (Bocquet, 2005;Monache et al, 2008;Yee et al, 2014), Monte Carlo algorithms using Markov chains (MCMC) (Gamerman and Lopes, 2006;Keats, 2009), and various stochastic sampling algorithms (Zhang et al, 2014(Zhang et al, , 2015. Deterministic methods use cost functions to assess the difference between observed and modeled concentrations and are based on an iterative process to minimize this difference (Seibert, 2001;Penenko et al, 2002;Sharan et al, 2012).…”

“…An atmospheric dispersion module for radioactivity release evaluations using a Kalman filter technique has been developed as a part of diagnostic system for accident management in [8]. Different modified ensemble Kalman filters for atmospheric dispersion modelling have been recently proposed by Zhang et al [9], [10]. Particle filter based methods have been integrated with atmospheric transport model to improve model predictions [11], [12].…”

“…Furthermore, Kalman filter and its extended methods are also extensively used in data-driven modeling due to its extensive framework [9,10]. A modified ensemble Kalman filter for nuclear accident prediction was proposed [11,12]. Reddy et al utilized particle filter to improve diffusion model based on Gaussian multi-puff equation [13].…”
