 Purpose of changes (include the issue number and title text for each relevant GitHub issue):
 
-Resolves #1034 - Problematic hybrid coefficients in L99
+	The L93 hybrid coefficients had a discontinuous kink, or offset, creating an anomalously thin layer
+	in the 300 hPa - 100 hPa altitude range. This region overlaps with the L58 grid, but for some reason
+	the L58 grid didn't get contaminated like it was in L93. We aren't sure how this happened.
+	More here: https://github.com/ESCOMP/CAM/issues/1034
 
-. The fix is to correct the hybrid coefficients and make a new run
+	fixes #1034 - Problematic hybrid coefficients in L99
