to an international project (THORPEX) for skillful extended weather forecasting. The 4DVAR technique has been developed for a global CGCM on ES to produce global analysis data for 10 years.
International campaigns have been organized, including ADEC (Aeolian Dust Experiment on Climate impact) and ABC (UNEP/Atmospheric Brown Cloud) to measure and analyze Asian dusts and pollutants in order to reveal their chemical and physical characteristics.
The National Institute of Polar Research (NIPR) has successfully recovered the deepest (3035m thick) ice core from the bottom of the Antarctic ice sheet. Its deepest part is estimated as ~720kyr old based on the oxygen isotope profile obtained.
After several years of a feasibility study for the Program of the Antarctic Syowa MST/IS radar (PANSY) under Resolution 8 adopted at the XXIII IUGG General Assembly, NIPR will introduce a small pilot radar system at the Syowa station in the International Polar Year 2007-8.
MAHASRI, a new continental-scale experiment under GEWEX (Global Energy and Water Cycle Experiment under WCRP), has been implemented in order to develop a hydro-meteorological prediction system for Asian monsoon variability. Its intensive observation periods are planned in 2008-9 for the International Monsoon Year and the Year of Tropical Convection.
CONTRAIL, a project for high frequency, wide-coverage measurements of CO2 and other trace gases, has been started, using commercial aircrafts.
