  1. Action ES0903: Spectral Sampling Tools for Vegetation Biophysical Parameters and Flux Measurements in Europe • Participating countries: AT ,BE, CH, CZ, DK, DE, E, EE, ES, FI, FR, HU, IT, IR, NO, PL, • P, SE, TR, UK, NZ, AUS, CANADA, AR • Chair of the Action: Loris Vescovo, vescovo@cealp.itVice Chair: caroline.nichol@ed.ac.uk • COST Science Officer: Basak Kisakurek basak.kisakurek@cost.it http://cost-es0903.fem-environment.eu/ Working Group 1: Networking In order to build up a diffuse spectral sampling network, European scientists currently working in the optical sampling of fluxes are invited to participate to the COST activities (meetings, Short-Term Scientific Missions, training schools). WG1 is collecting information regarding the optical sampling activities carried out within the different research teams (both European and non-European). WG COORDINATOR : Pilar Martin (ES) mpilar.martin@cchs.csic.es WG CO-COORDINATOR : Manuela Balzarolo (IT) manuela.balzarolo@unitus.it Working Group 2: Intercomparison WG2 objective is to focus onmethodological, inter site and inter instrument comparison. A review of the different methods used to calculate reflectance is being carried out. WG COORDINATOR : Karen Anderson (UK) Karen.Anderson@exeter.ac.uk WG CO-COORDINATOR: Micol Rossini (IT) micol.rossini@unimib.it Working Group 3: New Instruments WG3 aims at testing standard instruments for continuous data collection and analysing commercial instruments to determine their potentialities and limits according to the specific needs of the optical sampling network. WG COORDINATOR : Alasdair Mac Arthur (UK) alasdair.macarthur@ed.ac.uk WG CO-COORDINATOR: Albert Porcar Castell (FI) joan.porcar@helsinki.fi Figure 1. Summer School on Optical sampling . July 2011 Objectives: To analyze the state of the art of the optical sampling approach to flux studies in Europe To standardize the tools and methods in the spectral sampling network approach, focusing on instruments intercalibration-intercomparison To discuss a common measurement protocol to be adopted in all the European sites To adopt standard sensors for across site continuous spectral data collection To expand the optical approach on the existing flux net community (e.g CarboEurope IP) and to provide valuable data for the ecosystem modelling community To assimilate long-term continuous spectral measurements into biogeochemical models and upscaling the ecosystem observations Working Group 4: Upscaling Spectroradiometric measurements across different ecosystems at different scales are analysed. The role of high temporal resolution spectral data at site level as an input to different models in scaling up terrestrial fluxes is being assessed. WG COORDINATOR : Enrico Tomelleri (DE) etomell@bgc-jena.mpg.de WG CO-COORDINATOR: Louis François (BE) Louis.Francois@ulg.ac.be Main Achievements or Expected Results: Standardized protocols and scalable models for extrapolating ecosystem fluxes in a wide range of ecosystems will be developed. New and old technologies will be intercalibrated, tested and marketed to the flux and remote sensing communities. Also, the interaction between the scientific community and the scientific instruments industry is expected to new lines of communication and the potential for sustained research and development. The testing of sensors for ground reflectance will be a significant step towards the improvement of standardized optical measurements in different ecosystem types and flux tower sites. The collection of long-term continuous spectral measurements across a wide range of ecosystems has the potential to greatly improve global models and the potential to further our understanding of global change.
