15. Notation¶

λF: Frontal area index
ΔQS: Storage heat flux
BLUEWS: Boundary Layer part of SUEWS

Fig. 15.1 Relation between BLUEWS and SUEWS¶
CDD: Cooling degree days
GDD: Growing degree days
HDD: Heating degree days
Bldgs: Building surface
CBL: Convective boundary layer
DEM: Digital Elevation Model
DSM: Digital surface model
DTM: Digital Terrain Model
DecTr: Deciduous trees and shrubs
EveTr: Evergreen trees and shrubs
ESTM: Element Surface Temperature Method (Offerle et al.,2005 [OGF2005])
Grass: Grass surface
BSoil: Unmanaged land and/or bare soil
Runoff: The water that drains freely off the impervious surface
SoilStore: The water stored in the underlying soil that infiltrates from the pervious surface
L↓: Incoming longwave radiation
LAI: Leaf area index
LUMPS: Local-scale Urban Meteorological Parameterization Scheme (Loridan et al. 2011 [L2011])
MU: Parameters which must be supplied and must be specific for the site/grid being run.
MD: Parameters which must be supplied and must be specific for the site/grid being run (but default values may be ok if these values are not known specifically for the site).
O: Parameters that are optional, depending on the model settings in RunControl.nml. Set any parameters that are not used/not known to ‘-999’.
L: Codes that are used to link between the input files. These codes are required but their values are completely arbitrary, providing that they link the input files in the correct way. The user should choose these codes, bearing in mind that the codes they match up with in column 1 of the corresponding input file must be unique within that file. Codes must be integers. Note that the codes must match up with column 1 of the corresponding input file, even if those parameters are not used (in which case set all columns except column 1 to ‘-999’ in the corresponding input file), otherwise the model run will fail.
NARP: Net All-wave Radiation Parameterization (Offerle et al. 2003 [O2003], Loridan et al. 2011 [L2011])
OHM: Objective Hysteresis Model (Grimmond et al. 1991 [G91OHM], Grimmond & Oke 1999a [GO99QS], 2002 [GO2002])
Paved: Paved surface
Q^*: Net all-wave radiation
QE: Latent heat flux
QF: Anthropogenic heat flux
QH: Sensible heat flux
SOLWEIG: The solar and longwave environmental irradiance geometry model (Lindberg et al. 2008 [FL2008], Lindberg and Grimmond 2011 [FL2011])
SVF: Sky view factor
θ: Potential temperature
tt: Time step of data
