The Scientific Program Committee (SPC) will prepare the program consisting of regular sessions scoped by three associations, as well as the joint symposia prepared by the collaboration of different association members. The regular sessions of the International Association of Meteorology and Atmospheric Sciences (IAMAS) encompass a broad range of topics within the field of atmospheric and meteorological sciences. Key areas of focus include atmospheric chemistry and global pollution, climate, clouds and precipitation, dynamical meteorology, middle atmosphere, planetary atmospheres and their evolution, polar meteorology, ozone, radiation, weather and climate extremes, and atmospheric electricity

The sessions in the International Association for the Physical Sciences of the Oceans (IAPSO) focus on a wide array of topics related to the physical sciences of the oceans. Key areas of focus include the mean sea level and tides, air-sea interaction, ocean mixing, ocean salinity, Tsunamis and other ocean hazards, ocean model development, marine meteorology, and marine geodesy and and geophysics.

The sessions in the International Association of Cryospheric Sciences (IACS) focus on the study of snow, ice, and frozen ground on Earth and other planets. Key areas of focus include snow and avalanches, glaciers and ice sheets, sea ice, interactions with atmosphere and climate, permafrost, planetary, and other ices of the solar system.

In addition to regular sessions within the remits of the IAMAS , IACS , and IAPSO , themes for joint symposia concerning interactions between two or three of the atmosphere, cryosphere, and ocean.
