Sankha show three plots.
Maybe use area under curve fit to VIL.
Maybe average the rate of change VIL.
Dan says Terry normalizes. Should try Terry method.

Discussion
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.
Tasks
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.

Tasks to Adjust Plots
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

Discussion
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.
Meet same time next week.

Discussion
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.
dBZ reflectivity is different. Not an exact indicator.
Work on report.

Discussion
* 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.
