Carnegie Institution Atmospheric-Electricity and Meteorological Data

Metadata Updated: February 27, 2019

The Department of Terrestrial Magnetism at the Carnegie Institute of Science conducted observations of atmospheric electricity and magnetic storms. In addition to observatories in Washington DC and Tucson AZ, the Department operated observatories in Watheroo, Australia, Huancayo, Peru, and Apia, Samoa. Included are climatological records as well as potential gradient and conductivity data. Observations were conducted between 1916-1956, contained in 92 boxes. In addition to monitoring magnetic events, the observatories initially studied the variation of the electric potential and conductivity of the air, earth currents, cosmic rays, and disturbances in the Sun's chromosphere. They also provided meteorological information for the benefit of the local regions. DTM developed and supplied equipment for Huancayo and Watheroo for magnetic, electrical, cosmic ray, and seismic investigations.
