A primary objective of the 1995 and 1996 Flatland boundary layer experiments, known as Flatland95 and Flatland96, was to measure and characterize entrainment at the top of the convective boundary layer. The experiments took place in the area near the

We spectrally analyzed high-resolution balloon measurements of vertical profiles of temperature and horizontal wind in the troposphere and lower stratosphere over very flat terrain in Illinois. This paper is principally concerned with spectra in the

The hypothesis that temporal averages of vertical motions over a single radar station are representative of weather systems large enough to be resolved by the radiosonde network is tested using data from the Flatland VHF radar, located in the very fl

An experimental field campaign to measure synoptic-scale vertical velocities was conducted from 5 to 11 January 1991 in the Urbana-Champaign, Illinois, region, which is in very flat terrain far from mountains. Both the Flatland and the Urbana wind-pr

The so-called adiabatic method for estimating vertical air motions under isentropic flow conditions can be used with wind and temperature data from a single station. With the advent of radio acoustic sounding systems, wind and temperature measurement

A knowledge of vertical air velocities associated with synoptic scale meteorological phenomena is important to practical weather prediction as well a:; to an understanding of these systems. At present, these vertical velocities a re inferred from a g

A new VHF clear-air Doppler radar has been constructed in very flat terrain near Urbana, Illinois. This radar, called the Flatland radar, as presently configured measures a profile of the vertical component of the wind velocity every 2.5 minutes. It

During the last decade, great progress has been made in the use of sensitive VHF and UHF Doppler radars (often called MST, ST, or wind profiler radars) to study the dynamics of the clear air in the troposphere and middle atmosphere. Currently used tw

Sensitive Doppler radars can measure the Doppler spectrum of echoes from refractive index irregularities in the clear air. In this paper horizontal winds estimated from the mean Doppler shift measured by the Sunset VHF Radar, near Boulder, CO, are co
