  * AMS poster.
  * Working on NASA proposal, due next Friday.
+===== 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.
