ABSTRACT

Ground-based remote sensing profilers fill an important gap in current observing networks by providing continuous, unattended measurements of the planetary boundary layer. Such frequent observations are especially important during the night when thermodynamic and kinematic fields exhibit large spatiotemporal variabilities. In this talk, I will first describe the forecast value of profiling instruments for the specific problem of bore-driven nocturnal convection and then proceed with a critical discussion on some of the outstanding challenges in the assimilation of remotely sensed measurements. Special emphasis will be placed on the need to develop new data assimilation methods which can rigorously account for the non-Gaussian characteristics of moisture variables.
