Unified Surface Analyses for all fronts drawn from the NWS Weather Prediction Center (WPC), Ocean Prediction Center (OPC), Tropical Analysis & Forecast Branch (TAFB), and Honolulu Forecast Office (HFO) from Dec 2006 through Dec 2022. Fronts are provided for full domain at the synoptic hours (0000 UTC, 0600 UTC, 1200 UTC, 1800 UTC) and for CONUS at the synoptic hours and at 0003 UTC, 0900 UTC, 1500 UTC and 2100 UTC. The full unified surface analysis domain is ranges from the equator to 80N and from 130E eastward to 10E. Code to read in this data can be found at https://github.com/ai2es/fronts. This data was used in the paper: Justin, A., Willingham, C., McGovern, A., Allen, J.T. (accepted with major revisions) Toward Operational Real-time Identification of Frontal Boundaries Using Machine Learning. To appear in Artificial Intelligence for the Earth Systems.
