AMSR-E products, which are accumulated over 10 years till the present, were used for data. First, it was verified that the quality of the processing data by the supercomputer system was equivalent to the standard product offered to the users. In process of verification, the subjects depending on a compiler or a processor architecture and those depending on the mathematical model of an algorithm were found out. The possibility of the improvement towards the future was discussed about this point. Next, the processing performance was evaluated and we found that reprocessing of all the data in which about 14 months was required can be considerably shortened within 22-day duration. Therefore, it is expected that the waiting period which offers data to a user can be shortened sharply.","subitem_description_type":"Other"}]},"item_3_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態:
