Changelog3 1 0

This is the changelog for Snowpack release 3.1.0

• code cleanup, debugging

  • renaming indices
  • more meaningful names for Alpine3D flags
  • re-indenting
  • small improvements for padding purposes
  • constification, aliases
  • effective c++ recommendations
  • define three albedos: parametrized, measured and current albedo
  • extra, advanced warnings enabled when compiling Snowpack in debug mode
  • implement a few << class operators, convenient for debugging
  • better debug/error messages

• elements merging, joining and suppression

  • fixed possible merging of snow and soil elements
  • fixed issues with elements merging and sums of mass contents
  • revise/improve joining/merging of elements, renaming suppression, merging, joining
  • the properties of two snow layers that are merged are computed by a weighted average on the ice mass
  • fixed numerous small bug when merging specific elements (very small element, large or small ice content, etc)

• mass and energy balance

  • redefinition of the implicit soil heat flux when soil and snow are present
  • the melt/freeze part of the internal energy change is now computed and written out in met file
  • mass balance checking script for postprocessing met files
  • energy balance checking script for postprocessing met files
  • change order of soil/snow heat flux and surface fluxes in order to achieve a better energy balance
  • PhaseChange is now called twice: after the temperature equation and again after waterTransport (if infiltrating water would need to refreeze). A call to initialize() and to finalize() must be done
  • better branching between implicit and semi-implicit boundary conditions strongly reducing oscillations in soil
  • improve energy balance by treating boundary heat fluxes explicitly in melt conditions
  • better handling of maximum allowed number of iterations for the temperature equation (depending on the number of elements)
  • more tests on masses in debug mode (using asserts)

• water transport

  • excess rain water that can not be stored in the snow is added to snowpack runoff
  • the water that can not be stored in a snow element is forwarded to the elements below through some kind of preferetial flow path
  • MS_RUNOFF has been changed in MS_SNOWPACK_RUNOFF and only contains runoff from a snowpack
  • fixed an index bug in WaterTransport::compSurfaceSublimation()
  • discard MS_TOTALMASS from output to sn_gui
  • better runoff "classification" for various cases

• compilation and tests

  • add automated tests
  • CMakeLists cleanup
  • better possibilities to find inishell and meteoio (including when check outs have been made alongside one another)
  • FindLibsnowpack cmake script has been fixed

• Miscellaneous

  • fixed invalid flags for using with Alpine3D, reduce log output
  • reuse more atmosphere/radiation classes from MeteoIO
  • properly print exceptions on all platforms
  • radiation on the East and West slopes was swapped...
  • improve the documentation by adding new graphics and a new page
  • new key: output hardness in newton instead of index
  • new key: CLASSIFY_PROFILE (set to false by default) in order to chose if the profile classification should take place (and unless otherwise specified, it won't take place anymore)
  • less insertions of out of range numbers into the database
