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.
