  1. Sea Ice Monitoring and Prediction in Japan Meteorological AgencyApril 2003 Office of Marine Prediction Climate and Marine Department Japan Meteorological Agency

  2. Data Flow of Sea Ice Monitoring in JMA GMS NOAA Meteorological Satellite Center DMSP SSM/I Sea Ice Section Japan Meteorological Agency Sapporo District Observatory Hakodate Marine Observatory NOAA NESDIS Coastal Observation Sea Ice Analysis Sea Ice Forecast Wakkanai, Kitamiesashi, Mombetsu, Abashiri, Nemuro, Kushiro Aircraft Observation Users Marine/Land Defense Force, Japan Coast Guard Fishery Sight Seeing Other Nations Coastal RADAR Hokkaido University

  3. Numerical Sea Ice Model Area ; Southwest edge is located 42N, 140E. Number of the grid ; 71*71. Resolution ; 12.5km Parameters SST ; Analyzed by NOAA AVHRR (MCSST method), and GMS Sea Surface Current ; statistical value Weather Prediction data ; RSM(Regional Spectral Model) and GSM(Global Spectral Model) 6hourly Equipment 3500/E540PS HITACHI

  4. Sea Ice Monitoring System in JMA(Future Plan) Data Acquisition Satellite Observation GMS，NOAA Observation by Aircraft Ship Coastal Observation DMSP RADARSAT ADEOS-Ⅱ Sea Ice Analysis in the Coastal Area of Hokkaido Global Analysis Sea Ice Analysis in the Sea of Okhotsk Whole Okhotsk Model Coastal Sea Ice Model Near Real Time Global Sea Ice Data Forecast of Sea Ice Conditions of Whole Okhotsk Forecast of Sea Ice Conditions near Hokkaido Boundary condition of Climate Prediction Model and Weather Prediction Model Sea Ice Information Near Hokkaido, Okhotsk and, Global Statistical Data Arcive Users Web in JMA

  5. RADARSAT Data Utilization 1. Purpose Sea Ice Analysis in detail in the Sea of Okhotsk For the appropriate initial data for Coastal Sea Ice Model and Whole Okhotsk Model Estimation of Sea Ice Thickness ( if possible ) Estimation of Sea Surface Current ( if possible ) 2. Requirement in JMA to for RADARSAT data Every 5 day’s data Ascending and Descending ScanSAR Wide mode 4 Scenes a day from December to May In a year, about 150 scenes are necessary for sea ice monitoring.

  6. Process of Making the initial data for Sea Ice Model Sea Surface Temperature Sea Surface Current Analysis Initial Data Numerical Sea Ice Model Numerical Weather Prediction Sea Ice Concentration/Extent Sea Ice Thickness Forecast Data Feedback Sea Ice Concentration/Extent Sea Ice Thickness At the first time of running the model, sea ice thickness is determined 20cm.
