    Retrieval and Evaluation of Global Surface Albedo Based on AVHRR GAC Data of the Last 40 Years by Shaopeng Li, Xiongxin Xiao, Christoph Neuhaus, Stefan Wunderle

    Published 2025-01-01
    “…In addition, GAC43, C3S, and CLARA-A3 estimate higher albedo values than MCD43C3 in low-vegetation regions, such as croplands, grasslands, savannas, and woody savannas. Besides the fact that the new GAC43 product shows the best stability covering the last 40 years, one has to consider the higher proportion of backup inversions before 2000. …”

    Uso do solo e Dinâmica dos Nutrientes nas Águas do Reservatório da Hidrelétrica de Manso no Estado de Mato Grosso, Brasil Central by Jeater Waldemar Maciel Correa Santos, Simoni Maria Loverde Oliveira, William Pietro de Souza

    Published 2013-07-01
    “…As a result it was found that in only 7 months the water lamina of reservoir had already covered more than 60% of the previewed area for filling leaving submerged almost the all original vegetation existing in the area, it was 62%covered with forests and savannas and 19% of grasses for grazing cattle. The decomposition of this organic biomass flooded has provided nutrients to the water, and has influenced in the time-spatial variation of concentrations of total nitrogen (NT) and total phosphorus (PT), especially during filling phase of the reservoir, where its contribution may have been more important than that resulting from the export of nitrogen and phosphorus for their sub-basins of contribution. …”
