A new automated small size lidar system (microlidar or MULID) has been developed and employed to perform aerosol measurements since March 2010 at Ny Ålesund (<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:msup><mml:mrow><mml:mn>78.9</mml:mn></mml:mrow><mml:mo>°</mml:mo></mml:msup><mml:mtext>N</mml:mtext></mml:mrow></mml:math>,<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:msup><mml:mrow><mml:mn>11.9</mml:mn></mml:mrow><mml:mo>°</mml:mo></mml:msup><mml:mtext>E</mml:mtext></mml:mrow></mml:math>), Svalbard. The observations have used estimate the PBL height by using gradient method based on abrupt changes in vertical profile monitor its temporal evolution. scope of present study is compare several approaches height, observations, meteorological radio soundings, a zero-order one-dimensional model parameterization turbulent kinetic energy budget within mixing layer, under assumptions horizontal homogeneity, neglecting radiation latent heat effects. case presented here for convective PBL, observed June order verify whether Gradient Method can be applied Arctic region obtain height. results obtained are good agreement with estimated analysis thermodynamic from sounding model.
