Krogulec, E., Sawicka, K., & Zabłocki, S., (2025), [Dataset] for Spatiotemporal Assessment of Groundwater Drought in a River Valley Aquifer Using Standardized Indices in Central Poland

his research is supported by four primary datasets, each contributing to the spatiotemporal assessment of hydrogeological drought in the Kampinos National Park, Poland: Precipitation Time Series (time series_precipitation.xlsx) This file contains monthly precipitation totals (in millimeters) recorded between January 1, 1999 and October 1, 2020. Data were collected from nine meteorological stations located within the Kampinos National Park: Izabelin, Dziekanów Leśny, Famułki, Kiścienne, Leszno, Pociecha, Wilków, Rybitew, and Granica.

Groundwater Level Time Series (time series_groundwater.xlsx) This dataset includes monthly measurements of groundwater levels (in meters above sea level, m a.s.l.) from 56 piezometers forming part of the Kampinos National Park monitoring network. The time coverage is consistent with the precipitation dataset: from January 1, 1999 to October 1, 2020. Meteorological Station Locations (location_precipitation stations.xlsx) This file provides the geographical coordinates (ETRF 1989 / Poland 1992 reference system) for the nine weather stations used in the precipitation monitoring network.
