abstract = "The Amazon biome contains more than half of the remaining tropical
forests of the planet and has a strong impact on aspects of
meteorology such as the planetary boundary layer (PBL). In this
context, the objective of this study was to conduct observational
evaluations of the daily cycle of the height of the PBL during its
stable (night) and convective (day) phases from data that were
measured and/or estimated using instruments such as a radiosonde,
sodar, ceilometer, wind profiler, lidar and microwave radiometer
installed in the central Amazon during 2014 (considered a typical
year) and 2015 during which an intense El NiņoSouthern Oscillation
(ENSO) event predominated during the GoAmazon experiment. The
results from the four intense observation periods (IOPs) show that
during the day and night periods, independent of dry or rainy
seasons, the ceilometer is the instrument that best describes the
depth of the PBL when compared with in situ radiosonde
measurements. Additionally, during the dry season in 2015, the
ENSO substantially influenced the growth phase of the PBL, with a
15 % increase in the rate compared to the same period in 2014.",
