| Abstract | This document is the final report of an evaluation of Clarus-enabled enhanced road weather forecasting used in the Clarus Demonstrations. This report examines the use of Clarus data to enhance four types of weather models and forecasts: The Local Analysis and Predictions System (LAPS), used to estimate initial conditions for atmospheric weather forecast models; The Weather Research and Forecast (WRF) atmospheric weather forecast models; The Model of the Environment and Temperature of Roads (METRo) road weather forecast model; The Pavement Precipitation Accumulation Estimation System (PPAES) tool for enhancing radar-based precipitation estimates. The results demonstrate the benefit of the Clarus System to enhance weather and road weather forecast and estimation systems. While the Clarus data did not appreciably improve the atmospheric forecasts, it did improve the estimates for the initialization data that fed those forecasts. The Clarus data did result in improved road temperature forecasts, particularly during the first 24 hours of the forecast. And, when used with the PPAES model, the Clarus data helped improve on estimates of the locations where precipitation was present, particularly in the winter months and at locations further removed from NexRad weather radar stations. |
