Meteorological Satellite Center (MSC) of JMA What is SATAID? SATAID ( SAT ellite A nimation and I nteractive D iagnosis) is a sophisticated display software visualizing meteorological information in multiple dimensions (spatial and temporal) , which assists forecasters to analyze and monitor continually weather parameters and phenomena for better meteorological services. Customize display Data overlay With NWP data Multiple Animation functions With observation data 8 8
Meteorological Satellite Center (MSC) of JMA What can we do by using SATAID? • With SATAID, you can … – Display (and overlay) satellite imagery and NWP data (and various observations i.e. SYNOP, SHIP, TEMP, Radar, Wind Profiler, ASCAT etc. if its format prepared) – Use many functions vertical cross-sectional chart, time-series chart, digital data output to CSV file...... – Save as a file including a package of all data your drawings and comments, which will be useful for trainings and case study archives – Analyze position and intensity of tropical cyclones 9
