CHALEUR ANTHROPIQUE, ESTIMATION : CAS De LOKLAHOMA CITY DIAGRAMME de L APPROCHE TOP-DOWN DISTRIBUTION TEMPORELLE STATISTIQUES RÉSULTATS, 17 heures ( maximum de jour) CONCLUSION Et FUTURE WORK
Sources Of Heat Releases Estimation Of Daily Total Energy Hourly Energy Releases Spatial disaggregating Grid Model Hourly Fluxes Data Representing The Heats Source At City/State Level At Year/Month/Day Diurnal Temporal Profile Population Vehicular Traffic City - Daily Industry State - Monthly/Annual
ANTHROPOGENIC HEAT: FORMULA HOURLY VALUES E : Daily Energy In a Defined Surface S ( Joules) E i : Energy at Hour I ( Joules) Q i : Flux at Hour I in S ( Watt/m 2 ) QC : Sum of 24 Hourly Fluxes ( Watt/m 2 ) QC =1
ANTHROPOGENIC HEAT: STATISTICS for OKC comparison of our estimates with Sailors DAILY VALUES (by Heat Source) DAILY CUMULATIVE HEAT FLUX (QC)
ANTHROPOGENIC HEAT in dense population areas OKLAHOMA CITY MAP, BLOCK GROUP LEVEL Census tract # Density: Persons/Square mile BG 3: BG 2: BG 6: BG 7: 4632 Daily Heat Flux: Watt/m 2 BG 3: 1032 BG 2: BG 6: 671 BG 7: In densely populated area « 3 » daily heat flux = 1032 W/m*2 (VS OKC average: 65)

ANTHROPOGENIC HEAT: Results for 17h CDT (on 250x250m model grid) Summer, OKC Surrogate: Population Total Heat Flux at 17h CDT * Daily QC ranges on any point from 0 to 573 [Wm -2 ]
ANTHROPOGENIC HEAT: Results Summer, OKC Surrogate : Population + Industrial Land Total Heat Flux at h = 17:00 QC From 0 to 1278 [Wm-2]
ANTHROPOGENIC HEAT: Results Summer, OKC Surrogate : Pop-Road + Industrial Land Total Heat Flux at h = 17:00 QC From 0 to 1858 [Wm-2]
CHALEUR ANTHROPIQUE, ESTIMATION : CAS De LOKLAHOMA CITY CONCLUSION distribuer de la chaleur anthropique par (Population + Road + Industrial Land ). Génération dune Base de donnée à haute résolution (200m) Pour des résolutions plus lâches que 200m: agrégation en utilisant avec Gengeo. Prochaines étapes Génération Des Flux sur la grille du modèle à 2.5 km et 1 km de résolution. obtention des données requises pour générer les flux pour Montréal et Vancouver (à voir)
