     Notes on tags used in MITgcmUV
     ==============================
+o thermodynamics sea-ice (thsice) is now tested with testreport.
+o test exp. advect_cs: use the standard cs32 grid ; update output.
 
+checkpoint52l_post
+o new land formulation:
+  a) use ground enthalpy as prognostic variable to ensure exact
+     energy conservation.
+  b) account for water temperature and for latent heat of freezing
+     in all processes (rain, run-off, ground storage)
+  c) compute surface and ground temperature implicitly.
+o aim_v23 modification for new land model:
+  a) Treat separately land / ocean / sea-ice surface fluxes
+     to allow implicit computation of land & sea-ice surface temp.
+  b) add snow precipitation.

 o fix problem (when 1 tile is empty) in min/max monitor.
