Geophysica Norvegica

I august 1917, på samme møte som V. Bjerknes, O. Devik, B. Helland-Hansen, Th. Hesselberg, O.A. Krogness, H.U. Sverdrup og S. Sæland opprettet Norsk Geofysisk Forening, ble det også søkt om å få opprettet en tidsskriftserie, "Geofysiske publikasjoner". Les mer under etableringen av NGF.
Geofysiske Publikasjoner (Geophysica Norvegica) kom for første gang ut i 1921. Helt frem til 1985 ble det trykket opp 299 artikler fordelt på 33 volumer. Her følger en oversikt over alle publikasjonene som finnes i hvert volum. De fleste titlene er angitt med aktive lenker og er derfor tilgjengelige som pdf-dokumenter.

Scanningen og tilretteleggingen av nedlastbare dokumenter er administrert av NGF sitt styre i 2007-2009. Geofysisk institutt i Bergen har finansiert scanning av volum 1 til 22, mens Meteorologisk institutt har finansiert digitalisering av volum 23 til 33.

Hele oversikten er også tilgjengelig i MS Word-format og inkluderer register over alle forfatterne.

Desember 2020: Tor Bergeron sin artikkel Über die dreidimensional verknüpfende Wetteranalyse. Erster Teil: Prinzippielle Einführung in das Problem der Luftmassen- und Frontenbildung. er oversatt til engelsk og utgitt i Bulletin of the American Meteorological Society med referanse:
