Introduction

The Japan Agency for Marine-Earth Science and Technology (JAMSTEC) is implementing the development of data and information service with the user's needs which is part of the "Development of technologies for the practical application of earth observation data" as one of the objective of the Data Integration and Analysis System (DIAS).

As a part of our activities, we provide sample integration and analysis products on this site. We are always open to hearing suggestions for the way of use of the products and providing dataset and so forth.

Among the objectives of "Development and research agenda for the conversion of earth observation data to scientifically and socially useful information", we are making available the following sample products and application examples to the public..

  • Ocean Reanalysis Products Global Ocean Reanalysis Product based on a 4D-VAR data assimilation using observational data obtained from vessels, buoys, satellites, etc.
  • Glacier Inventory Glacier inventory using a digital elevation model (DEM) and satellite data
  • Data Set of Land surface Processes over Eurasia Long-term hydrogical data set over Eurasian cold region.
  • West Sumatra Radar-Raingauge Integration Data Set Distribution of rainfall rate derived from radar and raingauge observations
  • Gridded Precipitation Data of the Asian Region Gridded precipitation data set of the Asian region, for the period 1997 - 2002, based on the daily values of precipitation observed by ground-based raingauges
  • Monsoon Asian Heat and Water Balance Dataset Climatic data of heat and water balance in monsoon Asian region.
  • Typhoon Tracks during the Early 20th Century Digital dataset of typhoon tracks during the early 20th century over the Western North Pacific
  • Historical rainfall dataset in the Philippines Daily rainfall dataset during the early 20th century of 41 stations over the Philippines including Yap and Guam
  • Link System Map of Ecosystem Global map for correlation coefficients between NDVI and air temperature, NDVI and precipitation, and NDVI and PAR

Data Integration and Analysis System (DIAS)

The purpose of the Data Integration and Analysis System (DIAS) is to contribute to the establishment of the "A System of Systems" which is declared in the GEOSS 10-years Implementation Plan. "DIAS" is a part of the Earth Observation and Ocean Exploration System under the National Key Technologies and it will collect a wide variety of observational data, and integrate and analyze them, and then provide data which are converted into scientifically and socially useful information such as data for analyzing factors responsible for climate changes in order to increase understanding of Earth processes, and promote prediction of the behavior of the Earth system.

DIAS was completed in March 2011 and moved to the Data Integration and Analysis System Project 2011-2015 (DIAS-P).
