Summary This technology is developedcontrolled by the National CentralUniversity, Central Weather BureauAcademic Sinica. The processingsystem is housed at NCUtechnical support is served in Taiwan to theglobal. The data is acquiredpreprocessed by CWB,followed bythe invention of the cloud properties retrieval algorithm package by NCU.The final retrieval algorithm package is evaluatedenhanced by thelocal observation from Academic Sinica. Therefore, the processing systemcan be assured for its performancereliability. This state-of-the-arttechnology has been recognizedapproved by AGU JGR-Atmospheres,the leading journal in Q1 level of the related research community by the anonymous peer reviewing in June 2020.

Scientific Breakthrough This retrieval package has the breakthrough technology that applied onthe satellite observation in geostationary orbit. The retrieval package caninfer the cloud microphysicaloptical properties from the multichannelreflectancebrightness temperatures from visible to inferredbands. This is first time in Taiwan that could retrieveestimate theclouds from satellite observation, along with the data quality control andassurance from local-adaptive enhancementimprovement in theprocessing system. The result had been evaluatedverified in multipleresources including both activepassive sensors onboard multiplepolar-orbiting satellites, radiosonde,ground-based active lidar.Therefore, the scientific data are assured for its performance andreliability.
Industrial Applicability The monitoring of the high-impact weather is an important service forindustry for the government. Therefore, the 24-7-365 surveillance of theatmospheric condition from geostationary satellite becomes the mostuseful technique to archive this goal, in particular under the scenario ofglobal changeincreased vulnerability due to extreme weather.Among the factors that related to high-impact weather, cloud plays animportant role that link to heavy rainfall, low cloud ceiling, atmosphericconvection initiationetc. These cause the strong influence in airport,harbor management. As a result, our technology help weather agencyand related authorities for the advanced applicationservice.
