Meeting next week, again Same time.

Attending: David Delene, Sankha Maitra, Andy Detwiler, Bruce Boe, Dan Gibert

* Sankha show plots shear/cape plots for 2017. * Has all the text files, need to put in program. * CAPE, BRN, 0-4 shear. * Be care of what to use.

• Sankha:
  • AMS Abstract.
  • Make environment plots that include Max Vil, average VIL.
  • Get plots for all 2017 cases.

Meeting next week, again Same time.

Attending: David Delene, Sankha Maitra, Andy Detwiler, Bruce Boe, Dan Gibert

• Sankha:
  • Need more plots - Use Area.

Meeting next week, again Same time.

Attending: David Delene, Sankha Maitra, Andy Detwiler, Bruce Boe, Dan Gibert.

• Calgary Issue - Reboot after meeting.
• Has two plots. Shear on X and Max VIL over Effective Seeding Period (20 Minute, till 20 minutes at end of seeding). Seed cases above 15.0 shear, Second plot - Average VIL for the Storm.
• 20 Days total for 2017.

• KE Flux - Look and see if good estimating hail.
• Again check out what Terry did for normalization. Do similar analysis, create plot.
• Use Area > 60 dbz. Plot this.

Meeting next week, again Same time.

Attending: David Delene, Sankha Maitra, Dan Gibert.

• Plot - Add labels.
• VIL Different between two values

• Different colors for each ASP with line.
• Remove points 20 minutes after the end of seeding effect.
• Add trend line after effect of seeding starts.
• Add axis and title labels.
• Normalized
  • Dan, normalize by middle point or points (2-3).
  • Normalize by max over all VIL.
  • Normalize by max before seeding effect.
  • Max VIL at largest 60 dbZ size.
• Averaging
  • Right now, just one point.
  • Run average of 2-6.
  • Difference before seeding effect and the points (1-6) after seeding effect
• Filter Data
  • Above 30 VIL,
  • Above 70 VIL,
  • All data. Indicate this filter different on plot title.

Will be in my Zoom Room after 2 pm on Friday.

Attending: David Delene, Sankha Maitra

• Plot Modifications

Meeting next week, again Same time.

  • Limit to 20 minutes after seeding for changes plots.

Meeting next week, again Same time.

Attending: David Delene, Sankha Maitra, Andy Detwiler, Bruce Boe (Not Attending), Dan Gibert

• Interesting Plot - Need to calculate things using program, first derivate. Calculate the average and total number of points.
• Second plot, fix labels.

• Sankha
  • Fix plots, I'll work with you.
  • Plot data with filter by wind shear.

Meeting next week, again Same time.

Attending: David Delene, Sankha Maitra, Andy Detwiler, Bruce Boe (Not Attending), Dan Gibert

• 15 Case example. Some interesting.
• Fixed things in code.

• Sankha - Do calculations for metrics.

Programming tomorrow and/or Friday.

Meeting next week, again same time.

Attending: David Delene, Sankha Maitra, Andy Detwiler, Bruce Boe (Not Attending), Dan Gibert

• Discussed the plots. Need to keep making more plots.
• Need committee meeting this semester.

Meeting next week, again same time.

Attending: David Delene, Sankha Maitra, Andy Detwiler, Bruce Boe, Dan Gibert

• Look at some plots that have ratios.

Attending: David Delene, Sankha Maitra, Andy Detwiler

* Talked about Kyle using Titan on Calgary. * Has put USB drive in computer. * Calculated average. * Discussed more stuff.

* Discussed topic proposal.

David and Sankha meet next week.

Attending: David Delene, Sankha Maitra, Andy Detwiler, Dan Gilbert

• Discussed plots of VIL_70
• Talked about doing running average.
• Need to talk about topic proposal and writing up.
• Talk about slide.

• Work on getting stuff on Wiki page.
• Work on code for the 60 dbz area.

Attending: David Delene, Sankha Maitra, Andy Detwiler, Dan Gilbert

• Used all point outside 100 km.

Attending: David Delene, Sankha Maitra, Andy Detwiler, Bruce Boe (No), Dan Gibert

* Got some code working for area derivative, but not easy to understand. Hence, talk about it next week.

Meet Next week at 4 pm.

Attending: David Delene, Sankha Maitra, Andy Detwiler, Bruce Boe (No), Dan Gibert

* Talked about ASCE committee. * Go Over Plots. Some plots have different ranges.

• Values great >60.
• Title should be the case.
• What are the zero values mean?
• The Zeros should be missing vlaue codes
• Auto scale x Axis
• Don't use yellow
• Use both color and symbols.

• All seed but CAPE > 500. Only two cases so include all.
• Try things out.
• Even which average > 60 dbz exclude zeros. Check the difference.

Meet Wednesday - January 6, 2020 4 pm.

Attending: David Delene, Sankha Maitra, Andy Detwiler (via phone), Bruce Boe, Dan Gibert

• Bruce, commented again to have dates as titles. Please work on easy stuff and get that done, and don't keep working on things that are hard or not working.
• Use ratio in term, better to use math formulas.
• Define the formula first before showing plots.

• After discussion, talked about importance of missing value code.

Meet same time next week.

Attending: David Delene, Sankha Maitra, Andy Detwiler (via phone), Bruce Boe, Dan Gibert

• Setup meeting to discuss your thesis project with Kyle Pederson, Gretchen Mullendore, Andy Detwiler, David, Marwa Majdi, Sankha. Kyle/Gretchen really interested in knowing about your project since Kyle is doing something similar. Setup an online poll and have everyone complete, maybe Wednesday at 3 pm. Check my calendar.

Same time next week.

Attending: David Delene, Sankha Maitra, Andy Detwiler, Bruce Boe (no), Dan Gibert

• Look at overall ratio data.

Meet next week.

Attending: David Delene, Sankha Maitra, Andy Detwiler (yes), Bruce Boe (yes), Dan Gibert (yes)

• COVID vac. were schedule today.
• Maxvil Swath for C40S52 example, get ride of smoke trails, just trakes. Zoom out. Don't use BSP, ESP, and PSP, Use words, before seeding, seeding, post seeding.
• Where is the 60 dbZ maximum, around 3.8 to 5.0. Looked at three storms, Bruce think of high reflectivity at 6-8 km.
• Question about interpretation of metrics.
• Include final piece of including interpretation.

Attending: David Delene, Sankha Maitra, Andy Detwiler (yes), Bruce Boe (yes), Dan Gibert (yes)

• Zoom out on the figure.
• Go with C40S52, leave the aircraft tracks but not the smoke trails.
• Need to finish report.

Attending: David Delene, Sankha Maitra, Andy Detwiler (no), Bruce Boe (yes), Dan Gibert (yes)

* Went over edits. Make new version.

Attending: David Delene, Sankha Maitra, Andy Detwiler, Bruce Boe, Dan Gibert.

* Bruce - Has everything you need. * Send - Me Thesis stuff.

Meeting - No more with Dan and Bruce. Meet when we can.

David and Sankha - Meet next week.

Attending: David Delene, Sankha Maitra, Andy Detwiler, Kyle Pederson

* Discussed Alberta Project In General. * Sankha gave overview of the project via existing slides.

• Need to fix Map of the Project Area.
• Shouldn't use 'studied', it is Analysis.
• Should define ASP using dBZ and not just within the 100 km ring.
• Need slide to illustrate what “review” has done using titan display of radar data and flight tracks.
