2020a Release

Version 2020a (Released on 14 May 2020)

In a future release, we will ONLY deliver SUEWS along with
SuPy as a command line tool
suews-run: release of standalone SUEWS binaries will be stopped
to ease our maintenance load and to facilitate rapid developments. Users
will need to have Python 3.6+ to install SuPy:

python3 -m pip install -U supy

However, as the source code of SUEWS are public, users can feel free to
compile standalone binaries for platforms of their own interests.
:::

• Improvement

  1. A ponding water scheme is added in the automatic irrigation
     calculation; useful when a certain depth of ponding water to
     maintain in irrigation (e.g., flooding irrigation in rice
     crop-field).
  2. Irrigation fraction can be specified for all surfaces
     (previously only available for vegetated surfaces)
  3. A U-shape approach for calculating HDD/CDD is introduced to
     account for a wide comfort zone between heating and cooling
     critical temperatures.

• Changes

  1. A new [RoughLenHeatMethod]{.title-ref} option `5`: adaptively
     choose option [1]{.title-ref} for fully pervious surface or
     [2]{.title-ref} otherwise (if any impervious surface exists).
  2. A new column [H_maintain]{.title-ref} is added in
     [SUEWS_Irrigation.txt]{.title-ref} to set ponding water depth.
  3. New columns to specify irrigation fractions for non-vegetated
     surfaces in [SUEWS_SiteSelect.txt]{.title-ref}.
  4. A new scheme option
     [BaseTMethod]{.title-ref} in [RunControl.nml]{.title-ref} to set
     calculation scheme for HDD/CDD.

• Fix

  NONE.

• Known issues

  1. Wind direction is not currently downscaled so non -999 values
     will cause an error.
