Here, we used local weather road observations and the linkage between weather prediction and a radiation flux model (LDAPS-SOLWEIG) to calculate prediction information regarding habitual shade areas, sky view factor (SVF), and downward shortwave radiative flux by road direction and lane. Using the LDAPS-SOLWEIG model system, a set of real-time weather prediction data (temperature, humidity, wind speed, and insolation at 1.5 km resolution) was applied, and 5 m resolution radiative flux prediction data, with road resolution blocked by local weather and topography, were calculated. We found that the habitual shaded area can be divided by the direction and lane of the road according to the height and shape of the terrain around the road. The downward shortwave radiation flux data from local meteorological observation data and that calculated from the LDAPS-SOLWEIG model system were compared. When road-freezing occurred on a case day, the RMSE was 20.41 W\u00b7m\u22122, MB was \u22125.04 W\u00b7m\u22122, and r was 0.78. The calculated information, habitual shaded area, and SVF can highlight road sections vulnerable to winter freezing and can be helpful in the special management of these areas.<\/jats:p>","DOI":"10.3390\/rs14246379","type":"journal-article","created":{"date-parts":[[2022,12,19]],"date-time":"2022-12-19T08:41:41Z","timestamp":1671439301000},"page":"6379","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Study on Radiative Flux of Road Resolution during Winter Based on Local Weather and Topography"],"prefix":"10.3390","volume":"14","author":[{"given":"Hyuk-Gi","family":"Kwon","sequence":"first","affiliation":[{"name":"Research Center for Atmospheric Environment, Hankuk University of Foreign Studies, Yongin-si 17035, Gyenggi-do, Republic of Korea"}]},{"given":"Hojin","family":"Yang","sequence":"additional","affiliation":[{"name":"Research Center for Atmospheric Environment, Hankuk University of Foreign Studies, Yongin-si 17035, Gyenggi-do, Republic of Korea"}]},{"given":"Chaeyeon","family":"Yi","sequence":"additional","affiliation":[{"name":"Research Center for Atmospheric Environment, Hankuk University of Foreign Studies, Yongin-si 17035, Gyenggi-do, Republic of Korea"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,16]]},"reference":[{"key":"ref_1","unstructured":"Ibrahim, A.T., and Hall, F.L.
