Title: | A comparison between different methods to fill gaps in early precipitation series | Authors: | Camuffo, Dario Becherini, Francesca della Valle, Antonio ZANINI, Valeria |
Issue Date: | 2022 | Journal: | ENVIRONMENTAL EARTH SCIENCES | Number: | 81 | Abstract: | The aim of this work is to analyse and compare different methodologies to fill gaps in early precipitation series, and to evaluate which time resolution is reachable, i.e. monthly or daily one. The following methods are applied and tested to fill the 1764–1767 gap in the precipitation series of Padua: (1) using a relationship between monthly amounts and frequencies; (2) transforming a daily log with visual observations into numerical values through analysis, classification, and calibration; (3) substituting the missing values with an instrumental record from a nearby, contemporary station in the same climatic area. To apply the second method, the descriptions reported in the Morgagni Logs are grouped in 37 classes and transformed into numerical values, using for calibration the observed amounts in the Poleni record over the 24-year common period. As a third method, the series of Temanza and Pollaroli in Venice is used to fill the gap, and the application of a factor scale based on the ratio Padua/Venice tempted. The results of these three methods are discussed and commented. | URI: | http://hdl.handle.net/20.500.12386/32889 | URL: | https://api.elsevier.com/content/abstract/scopus_id/85132548032 https://link.springer.com/article/10.1007/s12665-022-10467-w |
