Status of networked phenology observation in China

Cover central and east part of terrestrial China

Near capital cities, parks

Traditional observation method

Relay on Volunteers: most of them are retired professors

Lack of sustainable financial support

Restored observation sites of phenology network in China (Ge et al., 2010)

Status of networked phenology observation in China

• Papers on phenology in Chinese

High frequent satellite data Ground observation is

fragmented at present: Isolated observationlocal, single sitessingle species or ecosystemIndividual held data

CERN : Good platform for networked phenology observation and research

Initiated in 1988 45 field stations with

well support infrastructures (2013), all owned by CAS

Covering most of the typical ecosystems in China; most of the stations far away from urban area, besides of urban stations.

Close Zero in synthesized, networked phenology observation and research

CAS owned Newly constructed

CAS owned, out of CERN

Phenology research opportunity and challenges using CERN

• Opportunity : CERN encourages Networked observation and researchNetwork research on Carbon-Nitrogen-Water

coupling Circle (Focus, Longest time in CERN, Largest financial support)

Network research on forest response to environmental factor change (Very good funding)

Underground ecological processes network research(e.g. RhizoNet, outlined in 2013)

Phenology research opportunity and challenges

• Phenology An powerful indicator for ecosystem response to

environmental factor ant its change Easy to couple with other plans It can be mapped Synthesizable with other data

Contour map of flowering timing of Robinia pseudoacacia L.(Li et al, 1999)

Phenology research opportunity and challenges

Personal Questions: How to couple phenology with other network observation and researches using phenocam approach? What’s the common scientific focus?How to mapping phenology based on phenocam data?How to integrate the phenology data to the spatial land observation data set? Such as land cover data.

Phenology research opportunity and challenges

• Challenges: How to use CERN as a networked phenology observation platform?Scientific Ideas: Climate change Sciences,

botany sciences…….Technologies: Phenocam network, satellite

remote sensing, how to design and couple them?

Sustainability: less output, less support

Push CERN into Phenology

• Scientific outputs forecast? What can be anticipated?

• International cooperation

• Negotiation e.g. CERN and China Phenology network ……
