We work with airborne CASI and AVIRIS hyperspectral data to estimate leaf biochemical and biophysical variables thought leaf and canipy modelling. We have worked studying the effects of chlorophyll fluorescence on leaf apparent reflectance through Radiative Transfer modelling. We currently work with MODIS and ASTER (EOS) satellite and AmeriFlux CO2 data over vegetation for carbon estimates using leaf, canopy and ecophysiological models. We continues hyperspectral research with Hyperion (EO-1) satellite, AVIRIS, CASI and HyMAP airborne sensors over forest and agricultural canopies for pigment, nitrogen and water content estimation. Our main research interests are related to forest stress condition, ecophysiological applications of remote sensing, and precision agriculture. Pablo J. Zarco Tejada, Director of Quanta, studied a Degree in Agricultural Engineering in Cordoba , Spain , at the Faculty of Agricultural Enginering and Forestry (ETSIAM). It was a 6-year degree + major final project. He worked with the Applied Physics Department in the major project entitled "The TIROS-NOAA satellites in solar radiation studies. The SGP4 orbital model application in the study of the temporal resolution". His first experience in Remote Sensing was in the one-year ERASMUS exchange program that he spent at University College Dublin (UCD), in Ireland . He studied his fifth year of the undergraduate program in Agricultural Engineering at the Faculty of Agriculture and also some courses at the Faculty of Civil Engineering. He worked at the Forest Institute for Remote Sensing Technology (FIRST), Department of Forestry. After getting a Degree in Engineering he got an INTERCAMPUS scholarship from the Spanish Ministry of External Affairs to spent a term at Lima , Peru , working in collaborative research in remote sensing at the Pontificia Universidad Catolica del Peru (PUCP). He studied a MSc in Remote Sensing at University of Dundee ( Scotland , UK ) at the Department of Applied Physics and Electronic and Mechanical Engineering (APEME). He did the research thesis at York University , working at the Centre for Research in Earth and Space Technology (CRESTech) and Department of Physics. The thesis was entitled "Correlations between CO2 fluxes and high spatial resolution reflectance imagery". He used multispectral casi data of 3 m spatial resolution and 16 bands collected by the airborne casi sensor (Compact Airborne Spectrographic Imager), data collected as part of the BOREAS-NASA project. The thesis was supervisedby Prof. J. R. Miller .

 

He got the PhD Degree at the Graduate Program in Earth and Space Science, York University ( Toronto , Canada ). Research work was supervised by Prof. John R. Miller and it was a collaborative research between York University , Centre for Research in Earth and Space Technology (CRESTech) and Ontario Forest Research Institute (OFRI). They developed optical indices from hyperspectral CASI data that are related to leaf biophysical and biochemical variables. The airborne CASI sensor collects data in different user-selectable modes: He used 7 channels for the Mapping Misssion (0.5-metre spatial resolution), 72 channels (7.5 nm spectral resolution) and 288 channels (2.5 nm) to develop the algorithms based on the spectral indices.
