Increasing vapour pressure deficit is not necessarily atmospheric moisture loss: seasonal structure of VPD change in Estonia, 1965–2024 — analysis code and derived data
Year: 2026
Type: software
Abstract: Python code, derived station and national series, trend tables and figures supporting the manuscript "Increasing vapour pressure deficit is not necessarily atmospheric moisture loss: seasonal structure of VPD change in Estonia, 1965–2024" (T. Saue), submitted to the International Journal of Climatology. The analysis uses daily observations from 20 stations of the Estonian Environment Agency (April–September 1965–2024) to estimate trends in temperature, saturation and actual vapour pressure, relative humidity and vapour pressure deficit (VPD); the scaling ratio of actual to saturation vapour pressure trends; a decomposition of VPD trends into temperature and humidity components; RH homogeneity tests; and the relationship between the end of the snow season and April humidity. The original daily station observations are not included; they can be obtained from the Estonian Environment Agency. See README.md for the required file formats and the order in which to run the scripts. This research was supported by the RITA+ programme, project PA1-KSV-KIPPER (RITA-AGROMET2), 2025–2026.
