Detailed Description

[RADIATIVE_FLUXES] parameters (heat plan §2.2, phase H3).

Defaults are RHEComponent's (rhemodel.cpp:43-47) except where noted. GLOBAL scope only in H3; per-element ranges are RHE's [RADIATIVE_FLUXES] semantics and refuse until a later phase. H6a keeps GLOBAL scope deliberately — plan §7 records why (the per-step solar position is computed once, not per element).

Member Data Documentation

albedo

double openswmm::RadiativeConfig::albedo = 0.0

Rs, reference default.

atm_emiss_coeff

double openswmm::RadiativeConfig::atm_emiss_coeff = 0.5

Brunt Aa.

emiss_landcover

double openswmm::RadiativeConfig::emiss_landcover = 0.97

εlc

emiss_water

double openswmm::RadiativeConfig::emiss_water = 0.97

εw

landcover_temp

double openswmm::RadiativeConfig::landcover_temp = std::numeric_limits<double>::quiet_NaN()

Land-cover radiating temperature, °C. NaN ⇒ use air temperature.

PE2. RadiativeExchange computed the land-cover longwave term from AIR temperature and its own header recorded that as a departure from the reference, which carries a per-element landCoverTemperature. The consequence is a daytime understatement: a sunlit canopy or a concrete wall runs well above air temperature and radiates accordingly.

The NaN sentinel — not a plausible number — is what keeps every pre-PE model bit-identical and makes "the deck set this" distinguishable from "the deck did not", the configured_source[] distinction one struct over. A default of, say, 20.0 would be indistinguishable from a deliberate 20 °C and would change every existing answer.

lw_reflection

double openswmm::RadiativeConfig::lw_reflection = 0.03

RL.

shade_factor

double openswmm::RadiativeConfig::shade_factor = 0.0

fs, 0 = unshaded

shortwave_wm2

double openswmm::RadiativeConfig::shortwave_wm2 = 0.0

Incoming solar Jin, W/m² (0 = night)

sky_view

double openswmm::RadiativeConfig::sky_view = 1.0

fsky, 1 = open sky

sw_mode

ShortwaveMode openswmm::RadiativeConfig::sw_mode = ShortwaveMode::CONSTANT

H6a. CONSTANT keeps shortwave_wm2 load-bearing and is the default, so an H3-era deck is unaffected.

sw_ts_index

int openswmm::RadiativeConfig::sw_ts_index = -1

Index into ctx.tables under TIMESERIES; -1 otherwise.
