2010/10/11
Measurements of polar organic marker compounds were performed on aerosols that were collected at a pasture site in the Amazon basin (Rondônia, Brazil) using a high-volume dichotomous sampler (HV...
Complexity and predictability of daily precipitation in a semi-arid region:an application to Ceará,Brazil
Complexity predictability daily precipitation semi-arid region
2009/11/9
Complexity and predictability of daily precipitation in a tropical semi-arid region (Ceará State, Brazil) is assessed by applying entropy concepts. Precipitation regimes in that region depend on sever...
