Natural Hazards and Earth System Sciences (NHESS) and Nonlinear Processes in Geophysics (NPG) – to the EGU. The open access journals Biogeosciences (BG) and Ocean Sciences (OS) had been launched via Copernicus Publications in March and November 2004, respectively. In 2005, EGU launched the open access journals Climate of the Past (CP) and eEarth in July and October, respectively through Copernicus Publications. The latter was replaced by Solid Earth journal in 2009. The open access journals The Cryosphere (TC) and Geoscientific Model Development (GMD) were released in 2007 via Copernicus Publications. In June 2007, the EGU launched Imaggeo, an open access database featuring photos and videos relating geosciences. In August 2008, the Atmospheric Measurement Techniques (AMT) journal was first published, and the journals Solid Earth (SE) and Earth System Dynamics (ESD) began publication in February and March 2010 respectively. In 2011, Geoscientific Instrumentation, Methods and Data Systems (GI) was first published. On 7 April 2013 the open access journals Earth Surface Dynamics (ESurf) and SOIL were launched via Copernicus Publications. In April 2018, EGU launched the open access journal Geoscience Communication (GC) and the compilation Encyclopedia of Geosciences (EG), a collection of articles in between traditional review articles and online encyclopediae. EGU's newest journals are Geochronology, launched in April 2019, and Weather and Climate Dynamics, launched in August 2019. Annales Geophysicae: covers the sciences of the Sun-Earth system, including space weather, solar-terrestrial plasma physics, and the Earth's atmosphere. Atmospheric Chemistry and Physics: covers the Earth's atmosphere and the underlying chemical and physical processes. It covers the altitude range from the land and ocean surface up to the turbopause, including the troposphere, stratosphere, and mesosphere. Atmospheric Measurement Techniques: covers remote sensing, in-situ and laboratory measurement techniques for the constituents and properties of the Earth's atmosphere. Biogeosciences: covers all aspects of the interactions between the biological, chemical, and physical processes in terrestrial or extraterrestrial life with the geosphere, hydrosphere, and atmosphere. Climate of the Past: covers the climate history of the Earth, including all temporal scales of climate change and variability, from geological time through to multidecadal studies of the last century. Earth Surface Dynamics: covers the physical, chemical and biological processes shaping the Earth's surface and their interactions on all scales. Earth System Dynamics: covers the functioning of the whole Earth system and global change. Geochronology: covers physical, chemical, and biological processes used to quantify time in all environmental and geological
