This study investigated haze conditions, and resultant air traffic impacts, at several major airports, including Atlanta (ATL), Newark (EWR), Chicago O'Hare (ORD), Denver (DEN), and Los Angeles (LAX). Results from this study show that haze conditions contribute to reduced airport arrival rates and often require traffic management initiatives to mitigate the effects of this weather constraint. Identified haze impacts include increased airborne holding, excess fuel burn, decreased airport arrival capacity, over-delivery, and delay. Additionally, this study investigated the frequency and accuracy of haze predictions from the Terminal Aerodrome Forecast (TAF) product, as well as the correlation of these forecasts to the use of haze-related traffic management programs. Results from this study will also demonstrate the difficulties associated with forecasting haze due to limited upper air observations and lack of reliability and correlation with the surface observations. Additional implications from weather forecast requirements and weather-translation perspectives are explored in this study.
