First decade of atmospheric electricity observations at Świder Observatory

Since October 1929 measurements of the atmospheric potential gradient (PG) have entered routine operation at the Magnetic Observatory in Świder, Poland. This started a new chapter in the history of the Observatory. Two Benndorf electrometers recorded continuously until September 1939. The war disrupted these observations as well as shattered efforts to publish the results of nearly a decade. Nevertheless, these early actions initiated by the Observatory management shaped its future as it became a contemporary atmospheric electricity station in the second half of the 20th century.
