Atmospheric boundary layers with weak stratification are relatively well described by
similarity theory and numerical models for stationary horizontally homogeneous conditions …

The nitrate radical, NO3, is photochemically unstable but is one of the most chemically
important species in the nocturnal atmosphere. It is accompanied by the presence of …

The Amazon Basin plays key roles in the carbon and water cycles, climate change,
atmospheric chemistry, and biodiversity. It has already been changed significantly by human …

Over the last 100 years, boundary layer meteorology grew from the subject of mostly near-
surface observations to a field encompassing diverse atmospheric boundary layers (ABLs) …

Flow in a stably stratified environment is characterized by anisotropic and intermittent
turbulence and wavelike motions of varying amplitudes and periods. Understanding …

Due to the major role of the sun in heating the earth's surface, the atmospheric planetary
boundary layer over land is inherently marked by a diurnal cycle. The afternoon transition …

The collapse of turbulence in the nocturnal boundary layer is studied by means of a simple
bulk model that describes the basic physical interactions in the surface energy balance. It is …

The analysis of momentum and heat fluxes from the Cooperative Atmosphere-Surface
Exchange Study 1999 (CASES-99) field experiment is extended throughout the diurnal cycle …

Planetary boundary-layer (PBL) structure was investigated using observations from a
Doppler lidar and the 325-m Institute of Atmospheric Physics (IAP) meteorological tower in …

Physical processes represented by the Monin–Obukhov bulk formula for momentum are
investigated with field observations. We discuss important differences between turbulent …
