Impacts of Space-based Measurements
 Direct broadcast allows products to be used worldwide
 Satellite data has been greatly improving global
weather forecast, short-term climate analysis and
diagnosis
 Quick, reliable space-based observations play key
roles in natural disasters monitoring, ecosystem and
environment monitoring
 Aviation safety, air quality monitoring, renewable
energy , are becoming new thrust for satellite data
 And today, Observations from space support
better understanding, predictions, mitigation and
adaptation of climate change
STRONG REQUIREMENTS:
for climate monitoring from space
 GCOS requirements
 GFCS requirements
 Response to climate change
 Operational monitoring of weather / climate
extreme events
 Public awareness
CHALLENGE: Scientific issues
-- Satellite-based climate products development
Climate signal from satellite observations –
accuracy, consistency, representativeness,
comprehensiveness,
Calibration - the foundation for high quality
climate products
Data analysis & reanalysis- satellite observation,
with other advanced data to generate the
climate dataset for Global Climate Model
Advanced inverse methodologies
CHALLENGE：Technical issues
-- data use and application
Data fusion for multiple sensors, multiple
platforms
Long term historic data re-processing
Access to large amount of data and products
Application outreach and user training
CHALLENGE: International Coordination
Observation plan coordination
R&D to operational satellites transition and
contingency
Data and products standardization, algorithm
and experience sharing.
Data policy and data sharing
ACTIONS: We need develop an architecture
for monitoring climate from space
 To collect and define requirements
 To develop space infrastructures and enhance
climate observing capabilities
 To promote open, easy and fast ways for
climate dataset access
 To focus on scientific and technical problems we
have to confront with, and lead to final solutions
 To conduct international cooperation
PERSPECTIVES: Benefits we expect from the development
of the architecture

CMA’s experiences over past 40 years
• Long term satellite plan at national level is crucial to
keep no-gap operation and continuous observations
• High priorities have been put on integrated climate
observing system including space-based & in-situ
observations.
• Open data policy and effective data management has
greatly promoted data application.
• Early user involvement is necessary for successful data
use.
• Broad national and international cooperation helps to
exchange data and expertise, and to foster the S&T
progresses.
Summary
• Due to strong requirements for monitoring climate from
space, it is necessary for WMO members to consider
developing an architecture to meet these requirements.
• CMA strongly supports the concept of the space-based
architecture for monitoring climate, and is willing to make
further contributions for its implementation.
• It is suggested that WMO space programme further
coordinate with other technical commissions,
organizations and space agencies to work out detailed
technical descriptions for the architecture based upon
current concept documents.
