Fy-1c polar orbiting meteorological satellite of china:
Satellite, ground system and preliminary applications
Ocean Products
FY 1C satellite has 1 short wave IR channel,
2 long wave IR channels and 3 ocean color
observed bands. These data can be used to
produce many products over ocean, such as
sea surface temperature, sea ice and ocean
color and so on. Table 6 is the summary of
ocean products. Figure 5 is an example of
global SST image.

Atmosphere Products
FY-1C atmosphere products include cloud
parameter, out going long wave
radiation(OLR) and water vapor total content.
These products are very useful for weather
analysis and research of climate changes.
Table 7 is the summary of atmosphere
products. Figure 6 is the contour of OLR
over China.

Summary
Since launch of FY-1C, the satellite has been
working in good condition. It passed through
the orbit test and checkout period perfectly.
It provides both HRPT and GDPT data day
and night. Many countries over the world
can receive HRPT data from FY-1C satellite
every day. The data processing system in
China has been providing many products for
research of meteorology.hydrology, climate
changes, agriculture and environmental
monitoring. China is willing to share FY-1C
satellite data and products with the
international community, and thus to make
contribution to the people worldwide.
