Boundary-Layer Meteorology publishes papers on the physical chemical and biological processes occurring in the lowest few kilometres of the Earth's atmosphere. During its existence Boundary-Layer Meteorology has become the primary medium for the publication of theoretical numerical and experimental studies of the atmospheric boundary layer over both land and sea surfaces. Subject areas covered in the journal include agriculture and forestry air pollution airñsea interaction hydrology micrometeorology the planetary boundary layer surface processes mesoscale meteorology numerical modelling of the lower atmosphere remote sensing and urban meteorology. Occasional special issues are published that cover a particular topic in great depth.
