AMSR-2 Successor Sensor
TANSO-2 Successor Sensor
GOSAT-GW & AMSR3Global Observation SATellite for GHG and Water Cycle
The GOSAT-GW satellite will carry two missions, AMSR3 and TANSO-3.◼ AMSR3, led by JAXA, will succeed AMSR series observations with new
high-frequency channels (166 & 183 GHz) for solid precipitation retrievals and water vapor analysis in numerical weather prediction.
◼ TANSO-3, led by Japanese Ministry of Environment (MOE), will improve observation capability of greenhouse gases from GOSAT-2/TANSO-2.
◼ Internal project approval review was completed in Nov. 2019, and became official project in Dec. 2019.
Orbit Specification◼ 666 km altitude (same as GOSAT) and
13:30 LT in Ascending node (same as GCOM-W)
Mission Targets of AMSR3◼ Understanding water cycle variation and impacts of climate change◼ Improvements in numerical weather prediction, typhoon analysis, etc.◼ Contributions to fisheries near coast ◼ Contribution to navigation support in polar oceans

Example of Collaborations (1):Aerosol Monitoring and Forecasts
Jeju Island (altitude:1950m)
(blocks the aerosol)
• The high and nearly continuous AOT over land
and ocean are estimated from Himawari-8/AHI
• Transports of aerosols are captured by utilizing
frequent (10-min) observations by AHI

• JAXA has provided the Himawariaerosol algorithm (L2, L3) to JMA, and JMA has implemented the algorithm to its operational system.
• JMA plans to start data assimilation of the Himawari aerosol in its operational system in January 2020.
• Data assimilation of aerosol by polar orbital satellites (e.g. GCOM-C/SGLI) will be the next target.

WMO’s Regional Specialized Meteorological Centre Tokyo for Nowcasting (RSMC Tokyo for Nowcasting) operated by JMA supplies National Meteorological and Hydrological Services (NMHSs) with graphical nowcasting products to help improve capacity for disaster risk reduction.JAXA and JMA started collaboration toward the utilization of GSMaP
data in the issuance of warnings by NMHSs in Asia and Pacific region through the RSMC Tokyo for Nowcasting.

GSMaP’s Contribution to WMO SEMDPSpace-based Weather and Climate Extremes Monitoring Demo. Project
WMO Space-based Weather and Climate Extremes Monitoring (SWCEM) Demonstration Project (SEMDP), East Asia and Western Pacific Regional Subproject initiated in 2018 (Kuleshov et al. 2019, DOI:10.5772/intechopen.85824).
JAXA participates to this subproject with the GSMaP, and provide the GSMaP_Gauge_NRTproduct with 19yr-climate normal.
Targets are heavy rainfall and drought from 5-days up to a month.
