CLIMATE MONITORING FROM SPACE-- challenges, actions & perspectives

Yang Jun

China Meteorological Administration

WMO Cg-XVI Side Event

An architecture for climate monitoring from space

Geneva, May 18, 2011


Impacts of space based measurements

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

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

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

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

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

ACTIONS: We need develop an architecturefor 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

PERSPECTIVES: Benefits we expect from the development of the architecture

  • Understand requirements from different aspects based on RRR

  • Receive guidance to space missions in both orbits and instruments

  • Share algorithms and experiences for the development of ECVs

  • Share data and products

  • Build an end to end climate monitoring system at national level

GeoSat: Considering applications in both weather and climate Long term plan has been made for steady transition from FY-2 to FY-4


Cma s contributions

CMA’s Contributions

  • More than 20 year’s satellite dataset for Climate use

  • WMO’s Regional Training Centres, Centres of Excellence(CoEs)

  • Involvements in international cooperation

    • CM

    • CGMS

    • GSICS

    • New membership of CEOS since 2010


Cma s experiences over past 40 years

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

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.
