Update urban LCZ parameter table with more reasonable values (#1969)
Browse files Browse the repository at this point in the history 
TYPE: enhancement

KEYWORDS: urban, parameter

SOURCE: Reported by Benjamin Fersch (Karlsruhe Institute of Technology, Germany), fixed by Alberto Martilli (CIEMAT, Spain)

DESCRIPTION OF CHANGES:
Problem:
Current urban LCZ parameter table includes some unreasonable values for urban morphology (e.g., too large road width) and thermal properties (e.g., CAPR, CAPB, CAPG, AKSR, AKPB, AKPG). The LCZ classification is mainly a classification based on morphology, rather than thermal properties, so it should use the same thermal properties for different LCZs unless users have specific information from other local data sources.

Solution:
Use morphological parameters correspond to mid-range values of Stewart and Oke 2012, and all the LCZ classes have the same thermal properties.

ISSUE: [For use when this PR closes an issue.](#1954)

LIST OF MODIFIED FILES: 
URBPARM_LCZ.TBL

TESTS CONDUCTED: 
1. The mods fix the problem.
2. It passed regression tests.

RELEASE NOTE: Update urban LCZ parameter table (URBPARM_LCZ.TBL) with more reasonable values.
