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 • 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 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 • 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
FY-3A FY-1D FY-2D 86.5 FY-2E 105 FY-2C 123.5 FY-3B CMA’s Contributions to Climate Monitoring from Space Current Satellites In-orbit
Climate Instruments onboard FY-3A/B TOU/SBUS:Global Ozone Monitoring ERB/SIM:Earth radiation budget 10
More Emphasis on Climate Monitoring Capabilities in Future Polar-orbiting Satellites • Hyper-spectral sounding; • Atmosphere Chemistry sounding(CO2,CH4) • GPS radio occultation; • Sea surface wind microwave scatterometer. Launch plan of FY-3 follow-ons
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 • 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 • 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.
