JAGUAR data assimilation system Whole neutral Atmosphere Reanalysis

Data Specifications

The JAWARA dataset was produced by the joint project of The University of Tokyo, Japan Agency for Marine-Earth Science and Technology (JAMSTEC), and National Institute of Polar Research (NIPR), under the support of the Core Research for Evolutional Science and Technology (CREST; Grant Number JPMJCR1663, FY2016-2021), funded by the Japan Science and Technology Agency (JST), and KAKENHI (Grant Number 22H00169, FY2022-2026), funded by the Japan Society for the Promotion of Science (JSPS). The dataset was produced using the Earth Simulator and Data Analyzer (DA) system at the JAMSTEC.

The source of the database should be duly acknowledged in scientific and technical papers, publications, press releases and other communications in case of using the data.

Example:
This study used the JAGUAR Data Assimilation System Whole neutral Atmosphere Reanalysis (JAWARA) which was produced with the Earth Simulator under the support of CREST sponsored by the Japan Science and Technology Agency (JST) and KAKENHI sponsored by the Japan Society for the Promotion of Science (JSPS).
