===== August 25, 2020 =====
Attending: David Delene, Andy Detwiler, Christian Nairy.

==== Discussion ====
  * Commit to ADPAA repository. Either checked out read only version (binary version). Look at using Develop method (source code). Look at $ADPAA_DIR/src/install file.  Developer Version Source Code Download of Package (Read/Write Access)

  mkdir ${HOME}/ADPAA && cd ${HOME}/ADPAA
  svn checkout svn+ssh://name@svn.code.sf.net/p/adpaa/code/trunk/src
  Where 'name' is your developer's username on SourceForge.

  * You have Electric Field having in process_all_capeex19 (Field project processing script).

  * On July 25, we have three classification files (Fritz Waitz, Shawn Wagner, Christian Nairy). Will compare results.

  * Andy talk about August 3, first flight. Shows presentation file. 15:03 segment Ex small < 0.3 kV. When close to core, get increase above 1 kV upto 4 kV (15:34 to 15:36). Not much electric field far from echo cores.

  * PHIPS Images Discussion on July 25, 2019
  Emma Had The Following Comments
  images 2-6,9-10 Frozen Droplet -> Droplet (these are liquid droplets that have broken in the inlet)
  images 7-8,14 Empty -> Not Classified (out of focus liquid drops), out of focus particles don’t have to be classified
  images 11-12,18,21,28,30,34 Irregular -> droplet (shattered water droplet)
After image 42 shattered water droplets were not anymore classified, which is fine.
  image 137,139,142-145,148,149,151,152,156 Not classified -> shatteringimage 138,140,141,146,147,153-155 Not classified -> irregular
  image 150 Not classified -> plate, aggregate

  Here on I checked only classified particles
  image 169,178 Irregular -> Shattering
  image 326 Irregular, aggregate -> column, sublimating (this is subjective)
  image 383 Sectored plate -> Side plane
  image 410 -> this plate is not rimed but has pockets. Therefore, I would not label it as pristine too
  image 478 Irregular, pristine -> Like plate stacked with column… difficult but not pristine
  image 479 also not pristine
  image 543 Irregular -> Plate

===== October 2, 2024 =====
Attending: David Delene, Christian Nairy.

==== Discussion ====
 * NASA proposal was submitted. Christian forward, my email from Monday to John/Joe.  Talked about the proposal ideas.  
 * Christian has AMS talk approved. Cloud physics.
   * GRL paper - Letter is shorter paper, we are observing chain-aggs in Winter storms.
 * Current, CapeEx19 paper, have not hear from Jerry, last heard since year. Pre-print of paper. Data Collection is getting done, Meta data is revised.  Will call John Wold to see about storage, 27 GB.
    * Preprint - arXiv, Arxiv.org. Use https://arxiv.org/list/physics.ao-ph/recent
    * Check with Journal to make sure pre-print is not an issue.
  * Andy - Copy of paper, Working on aerodynamic and electric forces on clouds. Orientation would change fast, count lightning. Calculate when aggregation is strong enough, paper in 1980. Two items, how cold can and still have sufficient aggregation. At warmer temperature, change would move easier, colder temperature can't move so faster. Orientation of ice crystal detected by polarmetric radar, from Colorado radar Chandra@colostate.edu. 
  * Getting progress in lab setup.  Christian connected high voltage supply to plates and it worked to charge. Need to make a measurement. Need something to move one plate so you can get different field strength. 
    * Look for rubber mat and rubber covers.  Look for something to move the plate.  Wood works will.  

  * Meet same time next week.

===== January 8, 2025 =====
Attending: David Delene, Christian Nairy.

==== Discussion ====
  * AMS presentation.
  * Make recording and send Andy. Do a talk on Monday later day with David at AMS.

===== January 29, 2025 =====
  Attending: David Delene, Christian Nairy.

==== Discussion ====
  * GRL paper, keep short, look for formal to convert to printed pagers.
  * Talk about motivation for GRL paper. Need some type of good modification paper at the start.
  * Add in your 4-5 figures.
  * AMS Review
    * Christian talk, person to talk about count mono-crystals.

===== June 11, 2025 =====
  Attending: David Delene, Christian Nairy, Andrew Detwiler.
  
==== Discussion ====
  * GRL Paper. Review of images, methodology details. 
  * Navy paper, need to ask Brain could we submit without Jerry and Paul, would it help.
  * Come out of freezer. 
  * Add Neural Network.

===== July 15, 2025 =====
  Attending: David Delene, Christian Nairy, Andrew Detwiler.
  
==== Discussion ====
  * Talked about the UK Meeting.  Talked about Navy project and paper.
  * XGBoots - When going to another flight, go away down.  Random sample generation. Had to make more images up, parameters up. Need a range values. The generated data was not help, it was hurting.  No doing too well to get chain-ag, good as non-chain. Data in balance is an issue. Overlaps.
  * Only have 1,050 chains.  Can do things to the images to create more images.
  * Talk about CNN. Works well on Unseen Data. Look at false positives.  Some single crystal.
  * Get 256 feature parameters.  Like stuff that goes into XGBoots, Get lots of different parameters. The 256 does pretty well.
  * Get large dataset to got XGBoots. ConvXGB. Get much better.
  * The idea is to have the same number of different types of particles.
  * Composition time.
  * Suggest - See what for area of chains identified.

  * JGL - Paper, Talk about electric field separating charges.

==== Items ====
  * What is the overall lesson? What does this mean for all crystals?  What about the science?
  * Science, we want to identify area of lot of chain-ags.
