Himawari-8/9  Himawari-8: Started the operation on 7 Jul. 2015  Himawari-9: under standby status, take over the operation in 2022  AHI (Advanced Himawari Imager) performs very well  New service and products: HimawariRequest, AMV-based surface wind, AOD Himawari follow-on program  Start discussion to put into operation around FY2029  User requirement and impact are investigated on enhanced VIS/IR imager, hyperspectral IR sounder (HSS), lighting imager,,,  Global and Regional OSSE for HSS  Technological trend surveys in Japan/US/Europe  Suggestions, comments and requests are highly welcomed!! JAXA Japan Aerospace Exploration Agency

Current operation  GPM-Core/DPR (NASA-JAXA): Dual-frequency Precipitation Radar (KuPR + KaPR), Feb 2014~  GOSAT/TANSO, GOSAT-2/TANSO-2 : FTS for GHG (CO2 & CH4), Jan 2009~, Oct. 2018~  GCOM-W/AMSR2 : Microwave imager, May 2012~  GCOM-C/SGLI: Multi-ch optical imager for monitoring radiation budget and carbon cycle, Dec.2017~  ALOS-2/PALSAR-2 : L-band SAR for monitoring environment, disaster and resource, May 2014~ Plans  ALOS-3 : Advanced optical imager, follow-on of ALOS/AVNIR2 (JFY 2020)  ALOS-4 : Advanced L-band SAR, follow-on of ALOS-2/PALSAR-2 (JFY 2020)  EarthCARE/CPR (ESA-JAXA) : Doppler cloud radar (JFY 2021) AMSR2 follow-on (no earlier than JFY2022)  Current status: pre-project phase since Sep. 2018. Expect to start phase-B in late 2019  Equivalent to AMSR2 except for additional high freq ch (166GHz and 183GHz)  Share satellite bus with GOSAT2 follow-on (666km alt, 13:30 LT in ascending node)   finer FOV (5% less), narrower swath width (1535km) JAXA’s Earth Observation Schedule
