From 6156b78dfd350e0514d2455badcd7eab9b7d2d31 Mon Sep 17 00:00:00 2001 From: Cenlin_He Date: Tue, 23 Jan 2024 11:32:59 -0700 Subject: [PATCH] Update urban LCZ parameter table with more reasonable values (#1969) 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.](https://github.com/wrf-model/WRF/issues/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. --- run/URBPARM_LCZ.TBL | 96 +++++++++++++++++++++++---------------------- 1 file changed, 49 insertions(+), 47 deletions(-) diff --git a/run/URBPARM_LCZ.TBL b/run/URBPARM_LCZ.TBL index 80e6809c17..450d765f9d 100644 --- a/run/URBPARM_LCZ.TBL +++ b/run/URBPARM_LCZ.TBL @@ -32,21 +32,21 @@ SIGMA_ZED: 4.0, 3.0, 1.0, 1., 1., 1., 1., 1., 1., 1., 1. # ROOF_WIDTH: Roof (i.e., building) width [ m ] # (sf_urban_physics=1) -ROOF_WIDTH: 31.7, 25.7, 17.6, 17.6, 17.6, 17.6, 17.6, 17.6, 17.6, 17.6, 10. +ROOF_WIDTH: 22.2, 22., 9.6, 42.86, 26.25, 13., 25., 28.9, 43.33, 23.8, 5. # # ROAD_WIDTH: road width [ m ] # (sf_urban_physics=1) # -ROAD_WIDTH: 98.9, 39.2, 108.0, 108.0, 108.0, 108.0, 108.0, 108.0, 108.0, 108.0, 108.0 +ROAD_WIDTH: 20., 14., 5.2, 50.0, 35.0, 13.0, 3.33, 32.5, 43.3, 28.6, 100.0 # # AH: Anthropogenic heat [ W m{-2} ] # (sf_urban_physics=1) # -AH: 100.0, 35.0, 30.0, 30.0, 15.0, 10.0, 30.0, 40.0, 5.0, 300.0, 0 +AH: 175.0, 37.5, 37.5, 25.0, 12.5, 12.5, 17.5, 25.0, 5.0, 350.0, 350.0 # @@ -54,7 +54,7 @@ AH: 100.0, 35.0, 30.0, 30.0, 15.0, 10.0, 30.0, 40.0, 5.0, 300.0, 0 # (sf_urban_physics=1) # -ALH: 20.0, 25.0, 40.0, 20.0, 25.0, 40.0, 20.0, 25.0, 40.0, 20.0, 0 +ALH: 20.0, 25.0, 40.0,20.0, 25.0, 40.0,20.0, 25.0, 40.0,20.0, 25.0 # # AKANDA_URBAN: Coefficient modifying the Kanda approach to computing @@ -232,90 +232,92 @@ DZGR: 0.05 0.10 0.15 0.20 # (sf_urban_physics=1,2,3) # -FRC_URB: 1.00, 0.99, 1.00, 0.65, 0.7, 0.65, 0.3, 0.85, 0.3, 0.55, 1.00 +FRC_URB: 0.95, 0.9,0.85, 0.65, 0.7, 0.6, 0.85, 0.85, 0.3, 0.55, 1.00 + # # CAPR: Heat capacity of roof [ J m{-3} K{-1} ] # (sf_urban_physics=1,2,3) # -CAPR: 1.8E6, 1.8E6, 1.44E6, 1.8E6, 1.8E6, 1.44E6, 2.0E6, 1.8E6, 1.44E6, 2.0E6, 1.8E6 +CAPR: 1.32E6,1.32E6,1.32E6, 1.32E6, 1.32E6, 1.32E6, 1.32E6, 1.32E6, 1.32E6, 1.32E6, 1.32E6 # # CAPB: Heat capacity of building wall [ J m{-3} K{-1} ] # (sf_urban_physics=1,2,3) # -CAPB: 1.8E6, 2.67E6, 2.05E6, 2.0E6, 2.0E6, 2.05E6, 0.72E6, 1.8E6, 2.56E6, 1.69E6, 1.8E6 +CAPB: 1.54E6,1.54E6,1.54E6, 1.54E6, 1.54E6, 1.54E6, 1.54E6, 1.54E6, 1.54E6, 1.54E6, 1.54E6 # # CAPG: Heat capacity of ground (road) [ J m{-3} K{-1} ] # (sf_urban_physics=1,2,3) # -CAPG: 1.75E6, 1.68E6, 1.63E6, 1.54E6, 1.50E6, 1.47E6, 1.67E6, 1.38E6, 1.37E6, 1.49E6, 1.38E6 +CAPG: 1.74E6,1.74E6,1.74E6, 1.74E6, 1.74E6, 1.74E6, 1.74E6, 1.74E6, 1.74E6, 1.74E6, 1.74E6 # # AKSR: Thermal conductivity of roof [ J m{-1} s{-1} K{-1} ] # (sf_urban_physics=1,2,3) # -AKSR: 1.25, 1.25, 1.00, 1.25, 1.25, 1.00, 2.0, 1.25, 1.00, 2.00, 1.25 +AKSR: 1.54,1.54,1.54, 1.54, 1.54, 1.54, 1.54, 1.54, 1.54, 1.54, 1.54 # # AKSB: Thermal conductivity of building wall [ J m{-1} s{-1} K{-1} ] # (sf_urban_physics=1,2,3) # -AKSB: 1.09, 1.5, 1.25, 1.45, 1.45, 1.25, 0.5, 1.25, 1.00, 1.33, 1.25 +AKSB: 1.51,1.51,1.51, 1.51, 1.51, 1.51,1.51,1.51,1.51, 1.51, 1.51 # # AKSG: Thermal conductivity of ground (road) [ J m{-1} s{-1} K{-1} ] # (sf_urban_physics=1,2,3) # -AKSG: 0.77, 0.73, 0.69, 0.64, 0.62, 0.60, 0.72, 0.51, 0.55, 0.61, 0.51 +AKSG: 0.82, 0.82, 0.82, 0.82, 0.82, 0.82, 0.82, 0.82, 0.82, 0.82, 0.82 # # ALBR: Surface albedo of roof [ fraction ] # (sf_urban_physics=1,2,3) # -ALBR: 0.13, 0.18, 0.15, 0.13, 0.13, 0.13, 0.15, 0.18, 0.13, 0.10, 0.13 +ALBR: 0.30, 0.30 0.30, 0.30, 0.30, 0.30, 0.30, 0.30, 0.30, 0.30, 0.30 + # # ALBB: Surface albedo of building wall [ fraction ] # (sf_urban_physics=1,2,3) # -ALBB: 0.25, 0.20, 0.20, 0.25, 0.25, 0.25, 0.20, 0.25, 0.25, 0.20, 0.20 +ALBB: 0.3, 0.3, 0.3, 0.3, 0.3, 0.3, 0.3, 0.3, 0.3, 0.3, 0.3 # # ALBG: Surface albedo of ground (road) [ fraction ] # (sf_urban_physics=1,2,3) # -ALBG: 0.14, 0.14, 0.14, 0.14, 0.14, 0.14, 0.18, 0.14, 0.14, 0.14, 0.14 +ALBG: 0.08, 0.08, 0.08, 0.08, 0.08, 0.08, 0.08, 0.08, 0.08, 0.08, 0.08 # # EPSR: Surface emissivity of roof [ -
