Forecasting extreme atmospheric events with a recurrence-interval-analysis-based autoregressive conditional duration model

Abstract

With most city dwellers in China subjected to air pollution, forecasting extreme air pollution spells is of paramount significance in both scheduling outdoor activities and ameliorating air pollution. In this paper, we integrate the autoregressive conditional duration model (ACD) with the recurrence interval analysis (RIA) and also extend the ACD model to a spatially autoregressive conditional duration (SACD) model by adding a spatially reviewed term to quantitatively explain and predict extreme air pollution recurrence intervals. Using the hourly data of six pollutants and the air quality index (AQI) during 2013–2016 collected from 12 national air quality monitoring stations in Beijing as our test samples, we attest that the spatially reviewed recurrence intervals have some general explanatory power over the recurrence intervals in the neighbouring air quality monitoring stations. We also conduct a one-step forecast using the RIA-ACD(1,1) and RIA-SACD(1,1,1) models and find that 90% of the predicted recurrence intervals are smaller than 72 hours, which justifies the predictive power of the proposed models. When applied to more time lags and neighbouring stations, the models are found to yield results that are consistent with reality, which evinces the feasibility of predicting extreme air pollution events through a recurrence-interval-analysis-based autoregressive conditional duration model. Moreover, the addition of a spatial term has proved effective in enhancing the predictive power.

Ergonomic system of forecasting and analysis of the probability of atmospheric air pollution by emissions of enterprises in the conditions of technogenic development of the world

“…The developed forecasting model is based on the following data sets: suspended particles (PM2.5, PM10), ozone (O3), nitrogen oxide (NO2), sulfur oxide (SO2) and carbon monoxide (CO), wind direction, wind speed, air temperature, weather conditions (snow, rain, etc. ), cloudiness, pressure [12,13,14].…”
