EPTA (Expanded Precipitation Type Algorithm) ICICLE Data


The EPTA (Expanded Precipitation Type Algorithm) ICICLE Data Set contains EPTA output for 'PWD' freezing drizzle algorithms. At the conclusion of ICICLE, the EPTA was run on data collected from 26 January - 8 March 2019 at each of five surface sites as part of the ICICLE (In-Cloud ICing and Large-drop Experiment) field experiement. The EPTA output for each site has been archived to include one-minute reports of ice accretion, ice accretion rate, EPTA present weather type, and PWD-22 present weather type.
