Technical Name Continuous Monitoring of the CloudRain from Geostationary Satellite
Project Operator National Central University
Project Host 劉千義
This technology is developedcontrolled by the National Central
University, Central Weather BureauAcademic Sinica. The processing
system is housed at NCUtechnical support is served in Taiwan to the
global. The data is acquiredpreprocessed by CWB,followed by
the invention of the cloud properties retrieval algorithm package by NCU.
The final retrieval algorithm package is evaluatedenhanced by the
local observation from Academic Sinica. Therefore, the processing system
can be assured for its performancereliability. This state-of-the-art
technology 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 on
the satellite observation in geostationary orbit. The retrieval package can
infer the cloud microphysicaloptical properties from the multichannel
reflectancebrightness temperatures from visible to inferred
bands. This is first time in Taiwan that could retrieveestimate the
clouds from satellite observation, along with the data quality control and
assurance from local-adaptive enhancementimprovement in the
processing system. The result had been evaluatedverified in multiple
resources including both activepassive sensors onboard multiple
polar-orbiting satellites, radiosonde,ground-based active lidar.
Therefore, the scientific data are assured for its performance and
Industrial Applicability
The monitoring of the high-impact weather is an important service for
industry for the government. Therefore, the 24-7-365 surveillance of the
atmospheric condition from geostationary satellite becomes the most
useful technique to archive this goal, in particular under the scenario of
global changeincreased vulnerability due to extreme weather.
Among the factors that related to high-impact weather, cloud plays an
important role that link to heavy rainfall, low cloud ceiling, atmospheric
convection initiationetc. These cause the strong influence in airport,
harbor management. As a result, our technology help weather agency
and related authorities for the advanced applicationservice.
