Drop size distribution comparisons between Parsivel and 2-D video disdrometers

Mean Drop Size and Drop Size Distribution in a Hanson Mixer-Settler Extraction Column

Comparison of Raindrop Size Distribution Measurements by Collocated Disdrometers

An impact-type Joss–Waldvogel disdrometer (JWD), a two-dimensional video disdrometer (2DVD), and a laser optical OTT Particle Size and Velocity (PARSIVEL) disdrometer (PD) were used to measure the raindrop size distribution (DSD) over a 6-month period in Huntsville, Alabama. Comparisons indicate event rain totals for all three disdrometers that were in reasonable agreement with a reference rain...

P2.5 Observations of Snow Particle Size Distribution with 2-d Video Disdrometer and Polarimetric Radar

1. INTRODUCTION Across much of the United States, and in many parts of the world, winter precipitation can come in many forms. It can range from all-liquid rain, to partially frozen particles, and completely frozen particles such as ice pellets or snow. The results of winter precipitation, then, are highly dependent on what type of precipitation falls. If rain falls into subfreezing environment...

Rotary Atomizer Drop Size Distribution Database

Wind tunnel measurements of drop size distributions from Micronair AU4000 and AU5000 rotary atomizers were collected to develop a database for model use. The measurements varied tank mix, flow rate, air speed, and blade angle conditions, which were correlated by multiple regressions (average R2 = 0.995 for AU4000 and 0.988 for AU5000). This database replaces an outdated set of rotary atomizer d...

Erad 2014 - the Eighth European Conference on Radar in Meteorology and Hydrology

Drop size distribution (DSD) measurements using ground-based disdrometers (point measurements) have often been used to derive equations to relate radar observations to the integral rainfall parameters (Atlas et al. 1999, Bringi et al., 2003, Kozu et al., 2006, Tokay and Short, 1996, Ajayi and Owolabi, 1987, Battan, 1973). Disdrometers such as JWD, MRR and several others have a major limitation ...
