1. EarthCARE/CPR Overview
CPR
The first space‐borne cloud radar with Doppler velocity measurement capability.
 W‐band (94GHz) nadir‐pointing Doppler capability (accuracy 1.3m/s)
 Antenna aperture 2.5m
 Variable PRF : 6100‐7500Hz Sensitivity : ‐35dBZ at 20km height
Radar ZDoppler

3. Ground Segment Development
Ground Segment
 EarthCARE will be operated by ESA Flight Operations Segment (called FOS).
 The observation data of EarthCARE will be received by ESA Ground Segment (called PDGS).
 JAXA Mission Operation System verification is completed in 2022.
 GS Validation Test between ESA and JAXA is completed in October 2023.
 JAXA GS review is planned in December 2023.

4. Preparation status for the launch and commissioning
Launch preparation
 JAXA space segment development completion review was completed.
 The launch site preparation plan of the CPR is under final confirmation.

JAXA initial operation team
 JAXA is preparing CPR initial operation as member of Integrated Commissioning Team organized by ESA.
 The Integrated Commissioning Team has already kicked‐off the joint activity between ESA and JAXA
toward the EarthCARE launch and operation.
 JAXA also preparing JAXA inside team which consists of JAXA high level management, JAXA CPR projectteam, ground segment development team, the project scientist, the scientific validation leader, andcommunication officers.
 This team allow the CPR launch and commissioning activities to be handled smoothly.
