EarthCARE is an Earth observation satellite ^[1]. It is designed to observe and collect data on Earth's atmospheric and surface properties ^[1]. The mission supports climate research by providing detailed measurements of clouds, aerosols, and radiation ^[1]. Its instruments are calibrated to ensure high accuracy in long-term environmental monitoring ^[1]. The satellite operates in a low Earth orbit to maximize observational coverage ^[1]. Data from EarthCARE is distributed to scientific institutions worldwide for analysis ^[1]. The project is a collaboration between the European Space Agency and the Japan Aerospace Exploration Agency ^[1]. Launch is scheduled for 2024 from the Vandenberg Space Force Base ^[1]. The satellite has a planned operational lifetime of at least five years ^[1]. Its observations contribute to improving climate models and weather prediction systems ^[1]. The mission is part of the European Union’s Copernicus program ^[1]. EarthCARE is the first satellite to simultaneously measure clouds, aerosols, and radiation in the same footprint ^[1]. The satellite carries four primary instruments: ATLID, CPR, MSI, and BBR ^[1]. Each instrument is developed by a consortium of European and Japanese research institutes ^[1]. Ground stations in Svalbard and Kiruna receive telemetry and science data ^[1]. Calibration and validation campaigns involve airborne and ground-based sensors across Europe and Japan ^[1]. The satellite’s data will be archived in the ESA Earth Observation Data Centre ^[1]. EarthCARE is the first mission in the Earth Explorer program to focus on the radiative balance of the Earth system ^[1]. The satellite’s orbit is sun-synchronous, crossing the equator at approximately 13:30 local time ^[1]. The mission is funded by ESA, JAXA, and participating national space agencies ^[1]. EarthCARE’s observations will help quantify the impact of aerosols on cloud formation and climate feedbacks ^[1]. The satellite’s data products will be freely accessible to the global scientific community ^[1]. The project has undergone extensive pre-launch testing at ESA’s ESTEC facility ^[1]. EarthCARE is expected to provide unprecedented insights into the interactions between clouds, aerosols, and radiation ^[1]. The satellite’s design includes redundant systems to ensure mission continuity ^[1]. Mission operations are managed from ESA’s ESOC in Darmstadt, Germany ^[1]. EarthCARE’s science team includes over 200 researchers from 25 countries ^[1]. The satellite’s launch vehicle is a H-IIA rocket ^[1]. The mission’s success will inform future Earth observation missions in the 2030s ^[1]. The satellite’s data will be used to validate global climate models and support policy decisions on climate change ^[1]. EarthCARE is the first satellite mission to combine lidar, radar, and radiometer measurements for a comprehensive view of the atmosphere ^[1]. The satellite’s instruments are designed to operate continuously for the duration of the mission ^[1]. EarthCARE’s data will be integrated into global atmospheric reanalysis products ^[1]. The satellite’s orbit allows for global coverage every 10 days ^[1]. EarthCARE’s launch is coordinated with other Earth observation missions to enable synergistic data collection ^[1]. The satellite’s onboard processor compresses data before transmission to minimize bandwidth use ^[1]. The mission’s science objectives are defined by the International Council for Science ^[1]. EarthCARE’s development has involved over 100 industrial partners across Europe and Japan ^[1]. The satellite’s thermal control system maintains instrument temperatures within strict tolerances ^[1]. EarthCARE’s data will be used to improve the representation of clouds in numerical weather prediction models ^[1]. The satellite’s communication system uses X-band and S-band frequencies ^[1]. EarthCARE’s mission is aligned with the United Nations Sustainable Development Goals ^[1]. The satellite’s payload is the most advanced of its kind for atmospheric profiling ^[1]. EarthCARE’s science data will be available to the public within 24 hours of acquisition ^[1]. The satellite’s attitude control system uses reaction wheels and magnetic torquers ^[1]. EarthCARE’s launch is subject to weather and range availability constraints ^[1]. The satellite’s power system is driven by dual solar arrays ^[1]. EarthCARE’s mission is the result of over 15 years of international scientific collaboration ^[1]. The satellite’s data will be used to assess the radiative effects of aerosols from wildfires and industrial emissions ^[1]. EarthCARE’s instruments are designed to withstand the harsh conditions of space for the duration of the mission ^[1]. The satellite’s data will be used to monitor changes in cloud cover and aerosol distribution over time ^[1]. EarthCARE’s mission is expected to set a new standard for Earth observation satellites ^[1]. The satellite’s data will be used to improve the accuracy of climate projections for the next century ^[1]. EarthCARE’s launch is the culmination of a joint European-Japanese space initiative ^[1]. The satellite’s science operations will be coordinated through a centralized data processing center ^[1]. EarthCARE’s data will be used to study the impact of human activity on atmospheric composition ^[1]. The satellite’s instruments are calibrated using onboard reference sources ^[1]. EarthCARE’s mission is supported by a dedicated ground segment with multiple data reception stations ^[1]. The satellite’s data will be used to validate satellite-derived climate data records ^[1]. EarthCARE’s launch is scheduled for the second quarter of 2024 ^[1]. The satellite’s design incorporates lessons learned from previous Earth observation missions ^[1]. EarthC
