Expected Deliverables 1. 10 -days composite f. APAR over some Carbo. Europe sites from 1998 -2001 2. Global monthly composite of spatially aggregated at 10 km x 10 km and 0. 5 ° x 0. 5° in latitude-longitude 10/6/2020 3 rd CAMELS Meeting 2 11 -12 November 2003

Task 1 10 -days f. APAR over 11 Carbo. Europe e sites from Sep. 1997 to Dec. 2001 n Do • This task was achieved on August 2003 f. APAR & associated products; & software to read/access products; & documentations were delivered to Galina Churkina (they should be available under the Carbo. Data web site this month). 10/6/2020 3 rd CAMELS Meeting 3 11 -12 November 2003

Task 1 How are they organized? • f. APAR time series in a 30 x 30 km window centered around the Carbodata sites • IDL code to read • pdf file for each site which contains … 10/6/2020 3 rd CAMELS Meeting 4 11 -12 November 2003

Task 1 Documentation file describes Name of Site Geographical coordinates Country Location of the Site Ref: Gobron et. al. (2003) ‘European Vegetation Activity from Space’, Carbo. Europe Sites, IES, EUR 20764 EN. 10/6/2020 3 rd CAMELS Meeting 5 11 -12 November 2003

Task 1 Overview of 4 Years time series 10 -days time series 10/6/2020 3 rd CAMELS Meeting Monthly time series 6 11 -12 November 2003

Task 1 Histogram and statistics using 10 -day (top) and monthly (bottom) FAPAR time series from 1998 to 2001 spatially averaged over 3 x 3 pixels over the central pixel. 10/6/2020 3 rd CAMELS Meeting 7 11 -12 November 2003

Single year analysis Task 1 At the central pixel Averaged over 3 x 3 pixels 9 x 9 pixels 10/6/2020 3 rd CAMELS Meeting 8 11 -12 November 2003

Task 1 Information associated with the spatial averaging procedure Limited variations between time -series illustrate ‘spatially homogeneous surfaces’ wrt the f. APAR product 10/6/2020 3 rd CAMELS Meeting 9 11 -12 November 2003

Task 1 10 -days f. APAR over Carbo. Europe ne o sites from Sep. 1997 to Dec. 2001 e. D b o T • To provide an extra piece of code to facilitate the reading of FAPAR time series when data are missing over the full window (Action on NG) • Additional sites to be extracted (Action on CAMELS drivers: which sites are their highest priorities ? ) 10/6/2020 3 rd CAMELS Meeting 10 11 -12 November 2003

Task 2 Do ne Global monthly composite spatially aggregated • A preliminary version of the software has been developed and is currently under testing. • It delivers series of products at multiple spatial resolutions, for example : 10 x 10 km & 0. 5 X 0. 5 degrees 10/6/2020 3 rd CAMELS Meeting 11 11 -12 November 2003

Task 2 Contents of the file for the monthly composite spatially aggregated @ 0. 5 x 0. 5 degrees Number of original pixels inside the aggregated one 10/6/2020 3 rd CAMELS Meeting 12 11 -12 November 2003

Task 2 Example of the global f. APAR monthly composite spatially aggregated @ 0. 5° x 0. 5° 0. 5 1. 0 June 2000 10/6/2020 3 rd CAMELS Meeting 13 11 -12 November 2003

Task 2 Example (30 % reduced) of the global monthly composite spatially aggregated @ 10 x 10 km : f. APAR June 2000 0. 5 1. 0 10/6/2020 3 rd CAMELS Meeting 14 11 -12 November 2003

Task 2 Example (100%) of the global monthly composite spatially aggregated @ 10 x 10 km 0. 5 1. 0 June 2000 10/6/2020 3 rd CAMELS Meeting 15 11 -12 November 2003

Task 2 e n o T DGlobal monthly composite of spatially aggregated e ob • Check all elements of the software (January/February 2004) • Finalize the content and format of the file (require CAMELS inputs: what additional fields are useful? ) • Apply on Year 2001 and deliver to CAMELS for testing 10/6/2020 3 rd CAMELS Meeting 16 11 -12 November 2003

What else ? ? • Is there any specific well-identified request from CAMELS that is not yet covered? • How are we (JRC), in practice, associated to the scientific interpretation of these products ? • What are the benefits of the f. APAR products and how do we evaluate them ? 10/6/2020 3 rd CAMELS Meeting 17 11 -12 November 2003
