Plan of SPICE Observation Experiments in Japan
The National Research Institute for Earth Science and Disaster Prevention (NIED), the
National Institute of Polar Research (NIPR) and the Japan Meteorological Agency (JMA) are preparing for the participation in the SPICE project. In the 2013/14 winter, NIED plans a field observation experiment at Joetsu, Niigata, and NIPR also plans an experiment at Rikubetsu,
Hokkaido using resources available under limited funding. The Japan Meteorological Agency
(JMA) will support the experiments and be the contact point of Japan.
Appendix I shows the outline of the experiments planned at this moment. When the details are determined, the “SPICE Site Commissioning Protocols” will be submitted.
Observation data can be provided to the SPICE community.
