                         the nocturnal boundary layer (NBL) and the prevailing turbulent 
                         regime during the campaign DRY-to-WET, dry to wet season 
                         transition period (September-November) of RaCCI/LBA 2002. 
                         Measurements of radiosonde (RS), tethered balloon (TB), automatic 
                         weather station (AWS) and SODAR (remote sensing device) were made 
                         over the pasture site (Faz. Nossa Senhora Aparecida - 10 ° 45S, 62 
                         ° 21W, 290 m) in the region of Ouro Preto DOeste RO. The turbulent 
                         flow regime was determined using the Monin-Obukhov parameter. The 
                         NBL heights (RS, BC and SODAR), ranging from 156.3 ± 57.9 m at 
                         sunset up to 301.0 ± 124.5 m on the early morning of the next day, 
                         showed similarity with data already obtained during the dry season 
                         over the same region. However the characteristic of the 
                         atmospheric stability was similar to previous data collected 
                         during the wet season. In other words, during the transition 
                         period from dry to wet conditions, the atmosphere is not fully 
                         established, showing characteristics of both seasons: the height 
                         of the NBL is similar to the ones during dry period measurements 
                         while the atmospheric stability presents the same behavior as 
                         during the wet period.",
