1 Acquisition of CHRIS-Proba data over a high relief area of the Pollino National Park (Southern Italy), an opportunity within the NERC ARSF 2004 flying season Dr. Alan Blackburn, Geography Dept.

2 The Pollino N.P. extends over 90,000 ha on the Lucania Rregion of the Appennine massif reaching an altitude of 2267m The belt up to 1200m is charcterized by scarce population of Quercus pubescent and Quercus cerris. Agricultural area present degradation symptoms confirmed by the presence of xerophitic praiers and substitution brushes. Higher level are characterized by large beech woods up to 1800m with dispersed small silver fir woods. Above the tree line are montane xerophytic praiers, calcareous cliff, junipers and Pino Leucodermis

9 2004 NERC project Quantify canopy biophysical variables related to vegetation stress from airborne remotely-sensed data in Mediterranean ecosystems Dr. Alan Blackburn, Geography Dept. Lancaster Univerisity Prof. Hamlyn Jones, School of Life Sciences, Dundee University Dr. Raffaele Casa, Dept of Crop Prod., Tuscia Univesity Dr. Rosa Maria Cavalli, CNR IIA LARA Dr. Stefano Pignatti, CNR IMAA LARA sites: Pollino N.P. Castel Porziano estate Maccarese farm site Sensors: CASI2 ATM LIDAR The overall aims of the project is to test and compare a range of novel and conventional approaches for the estimation of vegetation biophysical parameters on contrasting vegetation types and topographies

10 2004 NERC project The methods to be applied within the proposal include: i) Exploitation of hyperspectral CASI data to estimate pigment composition via decomposition methods and RT ii) Thermal multiangular approach to separate the temperature of shaded and unshaded area of canopy and soil of different canopy components iii) Exploit the directional information of multi-angular spectral data in no flat area. iv) Impact of LIDAR spatial information canopy geometry with hyperspectral CASI data to facilitate the extraction of spectral information from the scene Pollino field based measurements include acquisition of metereological data, vegetation structures and biochemistry, spectral analysis Measurement LAI Chlorophyll SLA fpar Spectra of endmembers Georeference Atmospheric correction Equipment required LAI-2000 Disc borer; Leaf sampling pole; liquid nitrogen vessel Disc borer; Leaf sampling pole Ceptometer Spectroradiometer DGPS Sun Photometer

11 Chris on Pollino Chris, 2004 NERC campaign and the previous remotely sensed data over Pollino represent a complete data set to: exploit multiangular images on a montane topography; fuse LIDAR and multiangular CASI2 - Chris data; Geocode different data sets with a 1 pixel of error?
