TL;DR: In this paper, a millimeter-wave cloud radar (MMCR) was designed to provide detailed, long-term observations of nonprecipitating and weakly precipitating clouds at Cloud and Radiation Testbed (CART) sites of the Department of Energy's Atmospheric Radiation Measurement (ARM) program.

TL;DR: In this paper, a 3.2-cm-wavelength Doppler radar was used to track the smoke plume for over 30 km, and the radar observed that the column consisted of a pair of counterrotating horizontal vortices with rising motion along the centerline and sinking along the edges.

TL;DR: In this paper, a new method was proposed to retrieve vertical profiles of the parameters of cirrus cloud microphysics that are important for the estimation of climatic feedback, such as particle characteristic size and ice mass content.

TL;DR: In this paper, three in-situ and five remote sensing techniques for measuring the height of the daytime convective boundary layer were compared, and good agreement between the different systems when the capping inversion was steep and well defined, and some variability when the stratification was not so sharply defined.

TL;DR: In this paper, a technique is presented to estimate ice cloud particle characteristic sizes and concentrations as well as the integrated ice water path from simultaneous ground-based radar and infrared radiometer measurements.
