At 9:36 a.m. on April 16, a Long March-4B rocket blasted off from
the Jiuquan Satellite Launch Center in northwest China and soon
sent the FENGYUN-3G meteorological satellite(FY-3G) into its preset
orbit. It is the third precipitation measurement satellite in the
world which can realize proactive measurement. Since then, China
has become the only country in the world which operates
meteorological satellites in four near-earth orbits.
FY-3G is equipped with 4 operational payloads, namely, Ku/Ka-band
dual-frequency precipitation measurement radar, microwave imager,
as well as optical imager and near-infrared multi-angle polarization
imager. Its main payload, precipitation measurement radar, is
first of its kind which is independently developed in the country.
Its ground system can provide data and IT resources supporting
platform for its operational application, and realize the quality
surveillance of operational data throughout the whole procedure.
Dr. CHEN Zhenlin, Administrator of China Meteorological
Administration (CMA) congratulated the successful launch of FY-3G,
and paid high tribute the distinguished contribution made by
meteorological and aerospace science and technology practitioners
to the development of FY meteorological satellite cause. He pointed
out that FY-3G was 20th FY meteorological satellite among the
FY meteorological family. Its successful launch has further
completed the low-orbit meteorological satellite constellation
networking layout, was instrumental in giving full play to the
advantage of low-orbit meteorological satellite observing network
of China, and would markedly improve the capability of early
warnings of global disasters like rainstorm.
Prof. Petteri Taalas, Secretary-General of WMO congratulated on
the launch of FY-3G. For several decades, he has been following
the development of FY meteorological satellite program.
He remarked that FY satellites are of state-of-the-art level
in the world, and their data were useful for many sectors
in many countries, in particular, less developed countries.
He thanked the open data policy in China’s meteorological
satellite field for playing a role in global meteorological
Dr. ZHANG Wenjian, Assistant Secretary-General of WMO expected
that FY-3G would contribute to global precipitation monitoring
and freshwater resource survey, make remarkable contributions
to disaster prevention and reduction, realizing the vision of
Early Warnings for All Initiative, and the assessment of the
impact of global climate change on global precipitation distribution.
The successful launch of FY-3G was China's vital contribution to the world.
Dr. ZHANG Zuqiang, Deputy Administrator of CMA, commented that
FY-3G will be a major initiative to protect the safety and
wellbeing of the people, and it will carry out in-orbit testing.
Meteorological practitioners should conscientiously make every
endeavor to make sure the data of FY-3G will be soon applied
in the work during this year's flood season.
Dr. CAO Xiaozhong, commander-in-chief of FY meteorological
satellite program, and Deputy Administrator of CMA, expressed
that FY-3G was the first satellite in China to proactively
measure the precipitation, will be applied in severe weather
monitoring and forecasting, and will play a role in fields
like ecological environment, energy, agriculture, and health.
Mr. Phil Evans, Director-General of the European Organisation
for the Exploitation of Meteorological Satellites (EUMETSAT),
stated that FY-3G would help negate the sometimes destructive
impact of severe weather occurrences on economies and societies
and he was very proud of the excellent bilateral cooperation.
Through bilateral operational data exchange agreement,
EUMETSAT ensures that CMA data, which will shortly include
those of FY-3G, reaches the operational user community in
Europe. He also anticipated a further bilateral collaboration.
Mr. CHEN Tao, chief forecaster from National Meteorological
Centre (NMC) expressed that FY-3G would further deepen the
insight into the three-dimensional structure of precipitation
and cloud, and micro-physical feature of cloud, and anticipated
its operational application in weather forecasting.
In the next 6 months, FY-3G will carry out in-orbit testing,
in a bid to verify its indicators in terms of satellite platform,
payloads and others, and tackle meteorological disasters like
rainstorm and typhoon during the main flood season.
China will launch another FY-3 meteorological satellite in August.
So far, China has 8 FY meteorological satellites in orbit, providing
data products and services for 126 countries and regions in the world.
