The atmospheric boundary layer (ABL) defines the volume of air adjacent to the Earth's
surface for the dilution of heat, moisture, and trace substances. Quantitative knowledge on …

Built environment changes the radiative, thermal and hydrological properties of the land
surface creating higher temperature over urban regions known as the Urban Heat Island …

A realistic reproduction of planetary boundary layer (PBL) structure and its evolution is
critical to numerical simulation of regional meteorology and air quality. Conversely …

Observations of atmospheric conditions and processes in cities provide the cornerstone for
advances in the understanding of urban climates and are crucial to improving the …

Continuous lidar observations of the top height of the boundary layer (BL top) have been
performed at Leipzig (51.3° N, 12.4° E), Germany, since August 2005. The results of …

The determination of the depth of daytime and nighttime mixing layers must be known very
accurately to relate boundary-layer concentrations of gases or particles to upstream fluxes …

Abstract The Vaisala ceilometers CT25K and CL31 are eye-safe single lens lidar systems
reporting attenuated backscatter profiles; they often operate 24 ha day in fully automated …

The impact of the urban heat island (UHI) effect on environmental and regional climate has
been receiving wide attention in recent decades. Taiwan, especially Taipei (located in …

The height of the atmospheric boundary layer (ABLH) or the mixing layer height (MLH) is a
key parameter characterizing the planetary boundary layer, and the accurate estimation of …

A novel method for estimating the mixing height based on ceilometer measurements is
described and tested against commonly used methods for determining mixing height. In this …
