  • Lots of particles between 0.1 to 0.3 are not good particles.
• What to do with two particles in the image.
• How to get size uncertain of particle to reflectivity.

• Select only large particle (>0.8), then make histogram of area ratio. Include particles < 0.1. Maybe use bin of 0.05 area ratio. Do histogram for whole hail time period.
• Get another meeting with Colorado setup.

• Andy Dewiler, James Klinman, David Delene

• Histrogram of area ratios. Looked at some plots. Looks like 0.4 area ratio to remove particles.

• James Klinman, David Delene, Andrew Dewiler

• David - Used James Code to display HVPS3 from lab droplet.
• James - Manual counting of Hail paper. Counted 10 seconds of data manually. Will have code to count them. Have been doing with HailSpec, but could work with HVPS3.
• David - Manual/program, get the best method and best spectrum. Get SODA to match by adjust parameters, which means doing a similar thing. Get the 1D data to match. Then process all the 1D data using this method Use that for Radar Comparison.

Use water processing, with like 5% and nothing to compare. kdp look at to get some water information. Kdp really really response to droplets in the air, maybe see water coming off the hail, kdp pick up large waterdrops.
