The International Symposium on Equatorial Aeronomy (ISEA) is held approximately every three to four years and is a major gathering of scientists around the world interested in the low-latitude atmosphere and ionosphere, as well as coupling with other latitudinal and altitudinal regions. The ISEA represents an opportunity for researchers to share their most recent results as well as discuss possibilities for future campaigns and experiments.

Each ISEA workshop is typically well attended. Participants at the previous ISEA, held in Taipei, Taiwan in May 2005 , numbered over 130, including graduate students, representing more than 15 countries. Results from past workshops have made significant contributions to our understanding of the low-latitude atmosphere and ionosphere, and, since the fourth meeting in Nigeria in 1972, have been compiled and published as part of a special issue of a peer-reviewed journal. Eighteen papers from ISEA-11 were published in a special issue of Annales Geophysicae (Vol 24, No. 5, 2006). Thirty papers from ISEA-10, held in Antalya Turkey, were published in a special issue of The Journal of Atmospheric and Solar-Terrestrial Physics (Vol. 64, 20 No. 12-14, 2002).

The ISEA Workshops focus on the following topics:
Lower and middle atmospheric dynamics
Mesosphere and lower-thermosphere dynamics
Ionospheric electrodynamics
Atmosphere/ionosphere/magnetosphere coupling
E- and F-region plasma instabilities and irregularities
Magnetic storm-time effects and Space Weather
New experimental techniques and instruments
Results from recent experimental campaigns
Future research trends and unresolved problems


The 12th International Symbosium on Equatorial Aeronomy will be held from 18 to 24, May 2008 on the island of Crete, Greece (a listing of all previous venues can be found below). The objective of the workshop is to bring together the leaders in the field of equatorial, low-, and mid-latitude aeronomy to advance our knowledge of these regions of the Earth’s atmosphere. Tutorials and reviews of recent advances will also be given. Topics for the workshops cover a wide range of research areas, reflecting the need to study the Earth’s ionosphere - atmosphere system in a coupled sense.

ISEA-12 will occur in an advantageous time in relation to advancing our under-standing of equatorial aeronomy. The International Heliophysical Year, 2007, will have just been completed, opening the door for new collaborations between international partners to study the complex system in great detail. The Climate And Weather of the Sun-Earth System (CAWSES) program will also have provided new avenues for cooperation amongst international partners. New satellites will provide exciting views of equatorial processes, specifically the COSMIC/FORMOSAT-3 program, the DMSP program, and the C/NOFS program (whose centerpiece satellite is now slated for launch in 2008). Coupled with the continued vigor of the international aeronomy community’s ground-based observing programs (radars, optics, etc) and theoretical pursuits, ISEA-12 promises to be a stimulating and fruitful workshop.


Financial support for previous meetings has been key in allowing many of the participants from developing countries as well as students to attend. Funding has been provided in the past by a multitude of organizations including the US Air Force Office of Scientific Research (AFOSR), the European Office of Aerospace Research & Development (EOARD), the International Association of Geomagnetism and Aeronomy (IAGA), the US Naval Research Laboratory (NRL), the US National Science Foundation (NSF), the US Office of Naval Research (ONR), the Scientific Committee on Solar-Terrestrial Physics (SCOSTEP), and the International Union of Radio Science (URSI).
