Abstract | Objetivando coletar parâmetros biofísicos e espectrais para avaliar dois modelos de simulação de reflectância de dosséis agrícolas (Suits e SAIL), foi instalado um campo experimental de trigo (Triticum aestivum, L.) em Campinas (SP). Analisaram-se as relações entre os parâmetros biofísicos e espectrais (medidos e calculados pelos modelos Suits e SAIL) e o ajuste dos modelos aos fatores de reflectância bidirecional, para os comprimentos de onda compreendidos entre 400nm-900nm. Além disso, o desempenho dos modelos foi avaliado em 4 bandas simuladas do sensor Thematic Mapper (TM1-azul; TM2-verde; TM3-vermelho e TM4-infravermelho próximo). A banda TM4 obteve a melhor correlação com os parâmetros biofísicos (área foliar, peso seco de folhas, índice de area foliar e biomassa). A banda TM3 foi a que obteve melhor correlação linear dos modelos Suits e SAIL com os fatores de reflectância bidirecional medidos no campo e entre os modelos para ângulo zenital de visada a 0º e a 30º. Os modelos superestimaram sistematicamente os fatores de reflectância bidirecional medidos nas duas configurações de visada, indicando uma tendência. Os modelos Suits e SAIL, tiveram desempenho semelhante nos comprimentos de onda do visível ao longo do ciclo fenológico do trigo. Apenas na banda TM4, as discrepâncias entre os fatores de reflectância bidirecional medidos e calculados pelos modelos foi maior no modelo Suits. Os modelos podem representar o fator de reflectância bidirecional de um dossel desde que as características deste dossel sejam fielmente descritas. ABSTRACT: With the objective of collecting biophyisical and spectral parameters to evaluate two canopy reflectance models (Suits and SAIL), an experimental field of wheat (Triticum aestivum,L.) was planted in Campinas (SP). The relations among biophysical and spectral parameters (mesured and calculated by the Suits and SAIL models) were analysed and, the adjust of the models to the bidirectional reflectance factors in the wavelength between 400nm-900nm. Also the performance of the models was evaluated in four simulated spectral bands of the Thematic Mapper sensor (TM1-blue; TM2-green; TM3-red ans TM4-near infrared). The TM4 band reached the best correlation with the biophysical parameters (leaf area, dry leaf weight, leaf arca index and biomass). The TM3 band was the one that reached the best correlation of the models Suits and SAIL with the bidirectional reflectance factor measured at the field and between the models in the both view zenith angle (0º and 30º). The models sistematicaly overestimated the bidirectional reflectance factors in the both view angle configuration , indicating a trend. The models Suits and SAIL had similar performance in the visible wavelenghts during the phenological cycle of the wheat. Just in the TM4 band, the discrepancy between the bidirectional reflectance factor measured and calculated by the models was bigger in the Suits model. The Suits and SAIL models can represent the bidirectional refiectance factor of any canopy, since the canopy caracteristics has been reliable described. |
