This study aims to investigate a method to classify humidityregimes based on different “states” characterization of the TropicalAtmospheric Boundary Layer (TABL), above forest and savanna areas,according with Mahrt (1991) methodology. In these analyses, radiosondeand tower day-time data obtained during field experiments have beenused. For the forest (Caxiuana, Para state), “COBRA-PARA” experimentdata were used (spanning the period from 06 to 13/11 of 2006), while forthe savanna (Daly Waters), “KOORIN” experiment data were used(spanning the period from 15/07 to 13/08 of 1974, in Australia). Theresults obtained for the two experimental sites show important humidityregime differences among the sites.
