Climatologia da altura da camada limite atmosférica na Amazônia Central.

The Planetary Boundary Layer (PBL) is the lower portion of the atmosphere and interacts directly with the surface. The height of the PBL is a key parameter for several áreas of knowledge, especially for Weather and climate forecasting, pollutant distribution and air quality. In this work, data from a ceilometer located at the ATTO experimental site (Amazon Tall Tower Observatory) were used to obtain the PBL height between the years 2014 to 2020. The results showed that in El Niño years the height of the PBL has greater amplitudes When compared to La Niña years. It was that the month with the greatest amplitude of the PBL height is September.
