Using a modified DNDC biogeochemical model to optimize field management of a multi-crop (cotton, wheat, and maize) system: a site-scale case study in northern China [PDF]

Biogeosciences, 2019
It is still a severe challenge to optimize the field management practices for a multi-crop system when simultaneously aiming at yield sustainability and minimum negative impacts on climate as well as atmosphere and water quality.

A case study of boundary layer ventilation by convection and coastal processes [PDF]

, 2007
It is often assumed that ventilation of the atmospheric boundary layer is weak in the absence of fronts, but is this always true? In this paper we investigate the processes responsible for ventilation of the atmospheric boundary layer during a nonfrontal

Physical Modeling of the Atmospheric Boundary Layer in the University of New Hampshire’s Flow Physics Facility [PDF]

, 2016
The atmospheric boundary layer is the lowest part of the atmosphere, and is defined by a region from the surface of the earth to approximately 500-1000m altitude in which air velocity changes from zero at the surface to the velocity of the wind at a ...

Overcoming the boundary layer turbulence at Dome C: ground-layer adaptive optics versus tower [PDF]

, 2009
The unique atmospheric conditions present at sites such as Dome C on the Antarctic plateau are very favorable for high spatial resolution astronomy. At Dome C, the majority of the optical turbulence is confined to a 30 to 40 m thick stable boundary layer
