The present report summarizes the contributions to geomagnetism and aeronomy study by Chinese researchers during the past quadrennial period 1999¡ª2002. Six papers are included in the report. In this report, one paper which is on the geomagnetism study mainly reviews the magnetic field measurement, spatial-temporal characteristics of varying magnetic field, the physical processes and model, four papers present the research advances on solar-terrestrial physics, including the middle-upper atmospheric physics, ionospheric physics, magnetospheric physics, solar upper atmosphere and interplanetary physics, and the other paper reviews the development of space exploration in China.
I would like to show my thanks to XU Wenyao, XIAO Zuo, YI Fan, PU Zuying, CAO Jinbin and FENG Xueshang for their review papers and to the members of the Chinese Committee for IAGA for their contributions to the report.
