SUMMA v3.2.0

SUMMA Version 3.2.0

Major changes

• Addition to compute wall clock time for each HRU and time step
• Fixes a bug that incorrectly writes scalarTotalET and scalarNetRadiation to output in cases where canopy calculations are skipped
• Added case_study folder and Reynolds Mountain East albedo decay experiment
• Fixes a bug where restart files are not read correctly in cases with the parallelization argument -g for setups that have >1 HRU per GRU

Minor changes

• Fixes a bug where solar angle incorrectly gets set to 0 during polar days
• Canopy ice content check in check_icond.f90 now generates a warning if ice > 0 for T > 0 instead of a graceful exit. Graceful exit still exists if ice > 1E-3.
• Add deflate (compression level) option to outputControl file -- default level is 4 if not specified
• Fixes an unnecessary rounding error on SAI and LAI values in PHENOLOGY routine
• Fixes a bug where the SUMMA version is incorrectly reported by "summa.exe -v"
• Fixes a bug that incorrectly writes scalarRainPlusMelt to output in cases where snow layers do not exist
• Changed part "(a,1x,i0)" to "(a,1x,i0,a,f5.3,a,f5.3)" in check_icond.f90 line 277 to print out error correctly.
• Adds scalarSnowDrainage variable when melting of the snow without a layer
• Changes the logic for creating the first snow layer: instead of creating the layer when snow-without-a-layer exceeds the maximum depth of the 1st layer, the first layer is now created if snow-without-a-layer exceeds the average of specified 1st layer minimum and maximum depth (zminLayer1 and zmaxLayer1_lower in localParamInfo.txt)
• Added documentation of lookup table provenance

v3.1.0

Version 3.1.0

• Initial addition of the "What's new" page
• Added pull request template
• Adds HRU/GRU info to error messages
• Fixes a segfault of mysterious origin when using JRDN snow layering
• Fixes a water balance error w.r.t transpiration
• Fixes the output message to report the correct solution type
• Adds tolerance to balance check in updatState.f90
• Changes all float data types to rkind, for "real kind", which is intended to make it easier to switch from double to single precision.

v3.0.3

This release changes state files so that they include the basin variables required to be used as initial conditions. It also implements changes so that if basin variables are not in the initial conditions they are automatically populated with defaults. There is also a new option (optional) in the file manager which allows for specifying the location of the initial conditions file.

SUMMA 3.0.2

This includes a couple of minor bugfixes/enhancements:

• Record soil and veg type tables in the global attributes of output files
• A fix for very small stability values
• Improved error message on reading forcing data
