title: Daily Water Levels of the Vistula River at Warsaw, 1799–2024: A Complete and Homogenized Long-Term Record

description: The dataset Vistula River Warsaw Daily Water Levels provides a continuous daily record of water stages of the Vistula River at Warsaw, comprising 82,453 observations from 1 February 1799 to 31 October 2024. Data are stored in a two-dimensional tabular format with one row per day and variables provided in columns.

The table contains the following fields:





date – calendar date in the format YYYY-MM-DD.




water_level_cm – daily water stage in centimetres relative to the reference gauge zero, homogenized and referred to the currently operating gauge Warsaw–Boulevards.




water_level_m_Kronstadt60 – water level converted to metres above sea level according to the Kronstadt 60 vertical reference system (m a.s.l.).




water_level_m_EVRF2007 – water level converted to metres above sea level according to the EVRF2007 vertical reference system (m a.s.l.).




data_type – classification of the record as observed (measured values) or reconstructed (gap-filled values).




original_observation – unadjusted water level observations recorded in the original measurement units, without any corrections or conversions.Units used over time: 

1799-02-01 – 1859-12-31: New Polish cal (≈ 2.4 cm)

1860-01-01 – 1879-12-01: English Imperial inch (≈ 2.54 cm)

1880-01-01 – 1910-10-31: Russian 1/100 sazhen (≈ 2.13 cm)

from 1910-11-01: centimetres (cm)




reconstruction_method – method applied in the case of reconstructed data, e.g. linear interpolation or gauge relationship.




remarks – additional information, notes on reconstructions quality.
