Observation data are reprocessed almost every year according to progress in computational model to obtain physical information from observation. As the amount of observation data grows day by day, reprocessing time of the data expands longer and longer. However, data latency is an important subject because quick access to earth observation data considerably encourages research into global environmental changes and their effects to our society. On this point, JAXA Supercomputer System Generation 2 (JSS2) helps us to solve the problem since it can enhance throughput of data processing by using a number of computing nodes. First, we have utilized JSS2 for reprocessing of GOSAT(GOSAT: Greenhouse gases Observing Satellite) observation data. GOSAT was launched on Jan. 23rd, 2009, and the data during 6.5 year period has been reprocessed in Nov. 2015. We obtained incredibly high throughput; 30 nodes (360 cores) of Pre-Post system of JSS2 were assigned and resulted in 33 times shorter latency. Next, we used JSS2 for GPM (Global Precipitation Measurement) Core Observatory that was launched on Feb. 28th, 2014. The data during 2.2 year period has been processed and 4 times shorter latency was achieved in June 2016 by using 3 nodes at a maximum. As a conclusion, it is shown that JSS2 is a powerful tool to improve data latency of Earth observation data.","subitem_description_type":"Other"}]},"item_5_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態:
