Project GMES EAGLE- Exploitation of Angular effects in land surface observations from satellites

Remote sensing approaches using wide field of view scanners such as the AVHRR have often obviated the angular dependence of reflected and emitted radiation. Therefore the accuracy of the geophysical products derived does not meet the requested requirements for user communities concerned with climate change, carbon and water cycles, etc. With the advent of a new generation of global imaging spectroradiometers capable of acquiring simultaneous multi-angle observations, both qualitatively new approaches as well as quantitative improvements in accuracy are achievable that exploit the multi-angle signals as unique and rich sources of diagnostic information.

Objectives

The overall aim of EAGLE project is to support Europe’s goals regarding sustainable development and Global Change, by facilitating the provision of enhanced quality data, information and knowledge. To approach this objective we develop a comprehensive method for the study of the angular effects on land surface products obtained from remote sensing data at regional and global scales.

    Because the new generation of satellite sensors includes the capacity to realize simultaneous multiangle measurements. The scientific community has the task to adapt their models to this new situation. This is the most important idea to develop EAGLE and therefore, their objectives are:

a)   EVALUATION-CORRECTION: To evaluate and to reduce the associated uncertainty with the angular effects in the historical (by means of a retrospective study of Europe, using Pathfinder NOAA Land data from 1981 to present) and current (ATSR, SEVIRI/MSG, MODIS, MERIS) sensors.

b)    MODELLING: To propose improved algorithms using the available multi-angular measurements to generate sensor independent bio-geophysical products.

c)    DEMONSTRATION: To provide a demonstration of improvements in biophysical parameters obtained with the proposed algorithms.

d)    VALIDATION: To validate models and products using in situ field data.

e)    APPLICATION: To provide a dynamical biophysical map of Europe that will be continuously updated by comparing modelling results with actual observations from the various sensor systems.

f)     RECOMMENDATION: To indicate the new algorithms and sensor configurations that should be considered in the future to improve the estimations of the biophysical parameters.

    EAGLE intends to create strong interfaces with the user community and with operational production services to be implemented in Europe in the GMES framework and this will contribute to the establishment of a European Capacity for the global monitoring of the environment.

  • LSIIT (Laboratoire des Sciences de l'Image, de l'Informatique et de la Télédétection)
    LSIIT (Laboratoire des Sciences de l'Image, de l'Informatique et de la Télédétection) is research unit UMR 7005 of the University Louis Pasteur - Strasbourg I, associated with Centre National de la Recherche Scientifique (CNRS) since 1986. The back-bone of the research activity of LSIIT is "Image Sciences", which constitutes the link between the three main teams composing the unit: two of them have research activities dealing with Computer Sciences for Imagery on the one hand, Image Processing and Robotic Applications on the other hand. The third one has its research activity in the domain of Remote Sensing for Earth's Observation. The Remote Sensing, Radiometry and Optical Imagery Research Group (TRIO) of LSIIT has activity and experience in remote sensing for Earth's observation since the early 80's. Research activities have been mostly in the thermal infrared domain in relation to land surface temperature as a key variable in energy fluxes analysis and determination. Research work has been conducted in direct and inverse problems for surface flux modeling, methodology for radiometric analysis of satellite data in the visible to thermal infrared domains and associated field radiometry for validation of retrieved parameters from low spatial resolution space-borne and high resolution air-borne systems. The group has developed original methods for spectral analysis of remotely sensed data in the thermal infrared domain, and for retrieving both the channel emissivities and the surface temperature, based on the measurement of the reflected solar radiation in the mid infrared band 3-4 µm, and the combination of day/night images. Development and realisation of NOAA/AVHRR-HRPT and METEOSAT-PDUS local receiving stations, fully operational since 1995, has allowed applying these methods to large-scale problems and extended areas, to study spatial and temporal variability of surface radiative parameters, and angular variability of surface properties of continental surfaces. More recent activities have been focused on theoretical problems raised by change of scales and heterogeneity, on modelling interaction of electromagnetic radiation with the surface in relation to active methods, laser remote sensing and polarimetry. The Group has been involved in many collaborations and programs or campaigns at national and international level (among them, HAPEX-Mobilhy 86, HAPEX-Sahel 91, EFEDA 91-and follow-on EC programs, MODIS/NASA and LSPIM/ESA) and has been responsible or partner in many contracts from public institutions as well as industries: CNRS, CNES, UE, ESA-ERS1 (ATSR data), Canada Center for Remote Sensing, MATRA-Cap-Systems, The expertise of the TRIO/LSIIT group is well recognised by the international remote sensing scientific communities through its strong publications in the international refereed journals as well as the role it plays in the international remote sensing scientific communities.

  • Barrax
    • FIELD - CAMPAIGN IN BARRAX, Spain (July - 2004): During the period 14thJuly to 21thJuly, three EAGLE partners' carried out field measurements according to the timetable, namely, GCU from the University of Valencia (Spain), Alterra from Netherlands and the University of Louis Pasteur from Strasbourgh (France). The field campaign was carried out in Barrax test site, situated in the Spanish plateau. During many years, this place has been used as a test area for agricultural research. This site is characterized by large and uniform land-use units. Field measurements of surface temperature, emissivity, reflectivity and fluxes were made in the experimental site. Angular measurements were made using a goniometric system joint with several TIR radiometers. To obtain the TIR emissivities, the TES ans box methods were used. The reflectivity measurements were made with spectroradiometers operating in the range 0.4-2.5 µm. Large aperture scintillometers were installed during the project phase. The campaign's goal is the validation of the different algorithms developed by the eagle partners. This campaign was carried out jointly with ESA SPectra bARrax Campaign (SPARC) and more than 50 researchers from Europe and United States took part in the campaign.

    FIELD-CAMPAIGN IN THE NETHERLANDS, The Netherlands (June-2006):

    During the period 11thJune to 17thJune, a new field campaign took place in The Netherlands; Two partners of EAGLE took part in this field campaign. Simultaneous measurements were carried out in Cabauw (grassland located in 51º58’00’’ N, 04º 54’00’’E, -0.7m a.m.s.l.), in Loobos (forest placed in 52º 10’02.8’’N, 05º44’38’’E, 52 m. a.m.s.l.) and Speulderbos (forest located in the following coordinates: 52º15’08.1’’N, 05º41’25.8’’E, 52m. a.m.s.l.). Three towers are located in these places, respectively. The mast in Cabauw was built to measure the relations between the state of the atmospheric boundary layer, land surface conditions and the general weather situation for all seasons; the mast situated in Loobos carries out continuous micrometeorological measurements and the tower sited in Speulderbos is not currently used for operational measurements.

     Over the fields, thermal infrared radiometric measurements using handheld radiometers described in before reports, surface energy budget measurements were carried out using a scintillometer and an eddy correlation system were installed in two towers, in Speulderbos, as well as a standard meteo-station, including a Kipp and Zoonen CNR1 radiometer and a goniometer system. Also, measurements of soil moisture were carried out. The measurements in the field were carried out at the same time that overpasses of the sensors; the sensors used were Airborne Hyperspectral System (AHS) by INTA, E-SAR system over DLR airplane and MIRAMAP L-band Microwave radiometer. The CHRIS-PROBA, MERIS, MODIS and AATSR imagery corresponding with the measurements will be acquired.

  • Land-atmosphere exchanges of water, energy and carbon dioxide in space and time over the heterogeneous Barrax site during SPARC 2004 and SEN2FLEX 2005
    In order to advance our understanding of land-atmosphere exchanges of water, energy and CO2
    in space and time over heterogeneous land surfaces, two intensive field campaigns were carried out at the Barrax agricultural test site in Spain in the period 12-21 July 2004 (SPARC 2004) and 8-14 July 2005
    (SEN2FLEX) involving multiple field, satellite and airborne instruments for characterizing the state of the
    atmosphere, the vegetation and the soil from visible to microwave range of the spectrum. Part of the
    experimental area is a core site of a 25 km2 area within which numerous crops are grown - on both irrigated and dry land - alongside fields of bare soil. The campaigns were carried out in the framework of the Earth Observation Envelope Programme of the European Space Agency (ESA) with the aim to support geophysical algorithm development, calibration/validation and the simulation of future spaceborne Earth Observation missions. Both campaigns were also contributions to the EU 6FP EAGLE Project. Emphasis of this contribution is on the in-situ measurements of land-atmosphere exchanges of water, energy and CO2 as well as the thermal dynamic states of the atmosphere, the soil and the vegetation.
