STUDYING EVOLUTION OF HYDROTHERMAL ALTERATION MATERIALS IN THE TURRIALBA VOLCANO TROUGH MULTISPECTRAL AND HYPERSPECTRAL IMAGES

We wonder if the simulations of the CMIP6 models represent the multidecadal variability of precipitation associated with the position of the ITCZ? We analyzed the outputs of the CMIP6 models together with paleoclimatic records from reconstructed multiproxy data from South America. Our results show that the north-south shift of the ITCZ ​​maintains a relationship with the oceanic region with higher sea surface temperature (SST) in the tropical river basin of the South Atlantic.
