Next Meeting - June 14, 11 CT.

• Pat Kennedy, Andy Dewiler, James Klinman, Ivan Arias.

• ICCP 2024
  • James - Update.
  • David - Update.
  • James - Uncertainty is interesting. How close was the plane and radar observations? Matching up data/. Why Tmatix, dis-dipolar, why not use. We have Tmaxtix setu.
  • Andy - What were they doing with radar processing? Create particle size distribution.
  • Pat - Exactly what were they doing.
  • David - Find paper on their work and send to group.
  • Pat - Nothing major, expand on things.
  • Chandra - Comments.
• Pat - Next steps. Processing all data from STEPS project (2000).
• Pat - At T-28 level. Will use 10 second data, in good format to get scattering from radar.
• Ivan - Finds the closest distance in time.
• James - Aaron new file with individual pbp data. Works with HVPS3 data, still working. There is issue with displaying the pbp images correctly.
• Andy - There is a factor of 4/1 scaling that is not applied to the pbp display, currently.
• James - Set the NetCDF file to 2. Set to 2 to get image data.
• David - Add the NetCDF options to ADPAA, set to default of 2.
• Andy - How long, does it take to processing.
• Ivan - Takes a 2-3 minutes processing for spectrum. Adjusting only air and ice. Working on getting the water amount. Use LDR to match aspect ratio.
• Andy - Size distribution with uncertainty bars. Can you use uncertainty to get radar uncertainty. Something good.
• Ivan - Yes, something to do.
• Andy - Want we have is a range of valves.
• James - Updated aspect averaging code. Can generate table of aspect ratio.
• Ivan - Can you use size bin aspect ratio? Yes.
• David - Can you weight the aspect ratio.
• Andy - Use LDR and Reflectivity, use anything else?
• Ivan - Yes, only LDR and reflectivity.
• Andy - An afternoon, can do a flight to see if water on the
• David - Drop off early.

• James - Add NetCDF option to ADPAA SODA processing.
• James - Different file for defining streaker file.
• David - Send file format to use.
• Ivan - Do AMS abstract draft.

• Andy Dewiler, James Klinman, David Delene

• 2 or 3 pm meet next week, Thursday September 5.
• Area ratio < 0.3, manually classified as Not Looked at / good / bad
  • 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.
• Need to figure out how many of the < 0.4 are real data.
• Maybe work on code at 1 pm tomorrow.

• Andy Dewiler, James Klinman, David Delene

• James will start giving weekly update on writting.
• Andy - Look at 10 second segments of data for all the passes.
• James - Fixed pbp program so everything is working again.
• James - Talked about combining the two errors. Use the larger error, instead of add them.

• James Klinman, David Delene, Ivan Arias, P. Kennedy, Andrew Detwiler

• Group meeting
• Andrew - Get an idea of images. Get an idea of what is going. Is the 1D and 2D are close together. Will work on this.
• James - Using 0.3 area to filter out bad data.
• Ivan - Removed threshold. How to handle uncertainty.

• James Klinman, David Delene, Andrew Dewiler

• Software identification, on Hail Spec.
  • The PbP has several methods defined within the file.
  • SODA decides if there are more than one particle.
• Uncertainty.
  • Discussed uncertainty. Having larger

• James - Figure out blog finding methods, so we can example how it works.
• James - Find reference for the 1995 Hail Sizing method, x-extent.

• James Klinman, David Delene, Andrew Dewiler

• Aaron Email - No reply yet.
• Writing Update. Will send update, but doing some.
• Compare 1D and 2D Concentrations, All sizing methods.
• Compare concentration from Hail Spec with published spectrum.
• Andy - Share stuff from Pat. Been looking at area with not too much hail. Should at other area, should look at some place without lots of cloud water.

• Meeting next Tuesday at 3 pm.

• James Klinman, David Delene, Andrew Dewiler

• Andy - Sent some papers with image of hail.
• Andy - File has all period identified by Paul Field. Size distribution. So we can check with their 10 second time period for time distribution.
• James - Tried one time period 2000 June 22 flight.
• Andy - Sometime there high counts in 2.5-3.0 cm bin, Paul took out. Not sure why this happen.
• James - Looking on papers I left in mail box.
• Aaron talked with James
  • Talked about how SODA draw circles around particles. There is an option (Keep Largest Particle), to exclude satellite particle (small particle).
  • James - Talked about how you get 1-D data from 2-D images.
