Application of artificial neural networks to frost detection in central Chile using the next day minimum air temperature forecast

Abstract: Predicting future climatic events is one of the key issues in many fields, whether in scientific or industrial areas. An artificial neural network (ANN) model, based on a backpropagation type, was developed in this study to predict the minimum air temperature of the following day from meteorological data using air temperature, relative humidity, radiation, precipitation, and wind direction and speed to detect the occurrence of radiative frost events. The configuration of the next day ANN prediction system allo… Show more

“…The majority of recent frost prediction regression methods [8], [9], [10], [11], [12], [13] predict the minimum temperature of the next 12-24 hours. The prediction models include, linear regression [8], [9], random forest [10], and ANNs [11], [12], [13]. The ANNs have the highest accuracy among the other model types [3].…”

“…advective) that give rise to frost (Fuentes et al, 2018;Perry, 1998;Snyder & de Melo-Abreu, 2005) Plants cold acclimate when they are exposed to low, but nonfreezing temperatures (slightly above the water freezing temperature) for several days or weeks and the period of exposure to light decreases, whilst being growth retarded (Larcher, 2003;Ruelland et al, 2009;Fürtauer et al, 2019). In this process, plant metabolism changes as a result of hormonal changes (Fürtauer et al, 2019;Galiba & Tóth, 2017); moreover, membrane proteins and lipid compositions change, and the concentrations of metabolites (protective substances) increase (Fürtauer et al, 2019;Hoermiller et al, 2018;Larcher, 2003).…”

“…Spring frosts are most relevant for temperate crops and can trigger huge economic losses (Guillaume et al., 2018; Ma, Huang, et al., 2019). Orchard losses of 506,000 ton, equivalent to about US $354 million, were the result of spring frost in central Chile in September 2013 (ODEPA (Oficina de Estudios y Políticas Agrarias) 2013; Fuentes et al., 2018), resulting in serious economic and social problems for the government, growers, and rural families (ODEPA (Oficina de Estudios y Políticas Agrarias) 2013; Beyá‐Marshall et al., 2019). Similar losses occurred in central and eastern USA in 2007, when spring frost resulted in economic losses worth more than US $2.0 billion, due to reductions in wheat ( Triticum aestivum L.), peach ( Prunus persica (L.) Stokes), apple ( Malus domestica (Borkh.)…”

“…Prediction of weather temperature in a crop field is a crucial issue, whether in the urban area or rural area. In [33], they have used the ANN model, but with another approach, their accuracy is good, but some conflictions also need to be resolved in terms of data. They have mainly sensors to get weather data from weather stations.…”
