For calibration purposes, surface temperatures and stomatal conductance of component vegetation types were also measured at ground level. Manual classification was compared with a range of automated classification methods to determine the most accurate method for the study area. The ?scale? for each cover type was characterized by analysing the frequency distribution of contiguous pixels of each cover type at 1.2 m. Temperatures of different surface components were estimated using different combinations of 1.2 m and 3.3 m data (using spectral angle mapper classification) as well as linear spectral unmixing and disaggregation approaches for extracting thermal information at sub?pixel resolution. The relative advantages of the different methods are discussed and a recommended strategy for integrating hyperspectral imagery at different scales to extract component surface temperatures in montado/dehesa?type systems is proposed.</style></abstract><notes><style face="normal" font="default" size="100%">doi: 10.1080/01431160500396485</style></notes><research-notes><style face="normal" font="default" size="100%">doi: 10.1080/01431160500396485</style></research-notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>3</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Jones, H G</style></author><author><style face="normal" font="default" size="100%">Archer, N</style></author><author><style face="normal" font="default" size="100%">Rotenberg, E</style></author></authors><secondary-authors><author><style face="normal" font="default" size="100%">Mencuccini, M and Grace, J and Moncrieff, J and McNaughton, K G</style></author></secondary-authors></contributors><titles><title><style face="normal" font="default" size="100%">Thermal radiation, canopy temperature and evaporation from forest canopies</style></title><secondary-title><style face="normal" font="default" size="100%">FORESTS AT THE LAND-ATMOSPHERE INTERFACE</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">canopy temperature</style></keyword><keyword><style  face="normal" font="default" size="100%">evaporation estimation</style></keyword><keyword><style  face="normal" font="default" size="100%">Portugal</style></keyword><keyword><style  face="normal" font="default" size="100%">Quercus ilex</style></keyword><keyword><style  face="normal" font="default" size="100%">Remote sensing</style></keyword><keyword><style  face="normal" font="default" size="100%">thermal radiation</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2004</style></year></dates><publisher><style face="normal" font="default" size="100%">CABI PUBLISHING</style></publisher><pub-location><style face="normal" font="default" size="100%">875 MASSACHUSETTS AVENUE, 7TH FLOOR, CAMBRIDGE, MA 02139 USA</style></pub-location><pages><style face="normal" font="default" size="100%">123-144</style></pages><isbn><style face="normal" font="default" size="100%">0-85199-677-9</style></isbn><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">We review the remote sensing of canopy temperature using thermal radiation and outline the main sources of error in the measurement of emitted thermal radiation and its use in canopy temperature estimation. The theory underlying different approaches to the use of these remote estimates of canopy temperature for the estimation of evaporation from forest and other canopies is discussed. The data requirements for the different approaches for remote estimation are compared. We illustrate the application of different approaches to local (branch-level) thermal remote sensing for the estimation of evaporation rate from Quercus rotundifolia trees in Portugal.</style></abstract></record></records></xml>
