Typically, maritime air has a CCN of 100 nuclei per cubic cm of air (/cc), mainly salt particles, and continental air has a CCN closer to 400 /cc, primarily dust and other particulates. In the Juneau case, the aircraft measured droplet concentrations ranging from as low as 3 /cc upward to 80 /cc!

precipitation reaching the ground in areas with radar echoes. To view this imagery, ensure that base reflectivity is loaded and then select the button on the toolbar. The reflectivity imagery is colorize by four main p-types: 1. Liquid 2. Freezing Rain 3. Sleet 4. Snow To view the raw base reflectivity data again, deselect the button.

The dual-pol melting layer algorithm uses the reflectivity, ZDR, and CC products to make its height estimations, and thus is impacted by the availability of sufficient radar echoes. Uses: This product can supplement observed ROAB data and model data in helping determine the approximate freezing/melting height and the approximate web bult 0 ...

Oct 7, 2021 · Using CC, ZDR, etc, you can get a great idea of the melting layer. I think you have two main options, depending on why you want the freezing line. Keep in mind, the freezing "line" is actually a 3-D surface the often folds on itself. Radar's don't …

Nov 8, 2024 · Freezing Drizzle is one of the trickiest, yet most impactful meteorological hazards to forecast. The most common error from a forecast standpoint regarding freezing drizzle is utilizing simulated radar / ice accumulation forecasts to effectively predict impacts.

The melting layer itself is determined by the radar using three methods: Automated detection of the melting layer signature in CC and BR (when possible) Environmental model data (RAP). The freezing level is the top and the bottom is assumed to be 500 m below; Manual entry of the melting layer top and bottom

Mar 22, 2012 · GR uses its own algorithms to calculate expected hail size and any mesos/TVSs, which are plotted on the radar display. These can be turned on or off using the respective buttons on the toolbar (below) or the View -> Show Hail Icons and View -> …

Jan 1, 2009 · The proposed freezing drizzle detection algorithm identifies drizzle echoes by first computing radar echo feature parameters at all sample gates for every 1.5° radar scan performed in the clear-air mode.

Freezing drizzle (FZDZ) is similar to freezing rain, but differs in terms of droplet size and the formation processes. Drizzle droplets are much smaller than rain with a typical diameter of 0.1mm versus 1-4mm for rain droplets.
