Climate models have too coarse a spatial resolution to properly represent cities at the relevant scale, and downscaled products often fail to account for urban effects. We propose here a methodological framework for producing high-resolution urban databases that are used to drive the SURFEX-TEB land surface and urban canopy models. A historical simulation is carried out over the period 1991–2020, based on a reanalysis of the city of Philadelphia (Pennsylvania, USA). The simulation is compared with observations outside and inside the city, as well as with a field campaign. The results show good agreement between the model and observations, with average summer biases of only −1 °C and + 0.8 °C for daily minimum and maximum temperatures outside the city, and almost none inside. The simulation is used to calculate the maximum daily heat index (HIX) and to study emergency heat alerts. The HIX is slightly overestimated and, consequently, the model simulates too many heat events if not bias corrected. Overall, HIX conditions at Philadelphia International Airport are found to be suitable proxies for city-wide summer conditions, and therefore are appropriate to use for emergency heat declarations.</div></div></div></div><div style="box-sizing:border-box;margin:0px;padding:0px;" id="reading-assistant-main-body-section"> </div><ul class="issue-navigation u-margin-s-bottom u-bg-grey1" style="background-color:rgb(245, 245, 245) !important;box-sizing:border-box;font-size:16px;line-height:24px;list-style:none;margin-bottom:16px !important;margin-left:0px;margin-right:0px;margin-top:0px;overflow:hidden;padding:0px;" id="issue-navigation"><li class="previous move-left u-padding-s-ver u-padding-s-left" style="box-sizing:border-box;float:left;left:0px;margin:0px;padding:16px !important 0px 16px;"><a class="button-alternative button-alternative-tertiary u-display-flex button-alternative-icon-left" style="--sd-ui-button-alt-border-bottom-colour-hover:#eb6500;--sd-ui-button-alt-border-bottom-colour:transparent;--sd-ui-button-alt-border-bottom-width:2px;--sd-ui-button-alt-colour-focus:#eb6500;--sd-ui-button-alt-colour:#1f1f1f;--sd-ui-button-alt-cursor:pointer;--sd-ui-button-alt-font-size:1em;--sd-ui-button-alt-gap:calc(0.5em - 2px);--sd-ui-button-alt-icon-background-colour-hover:transparent;--sd-ui-button-alt-icon-background-colour:transparent;--sd-ui-button-alt-icon-border-colour-hover:#eb6500;--sd-ui-button-alt-icon-border-colour:#1f1f1f;--sd-ui-button-alt-icon-external-link-size:0.625rem;--sd-ui-button-alt-icon-fill-hover:#1f1f1f;--sd-ui-button-alt-icon-fill:#1f1f1f;--sd-ui-button-alt-icon-padding:0.5rem;--sd-ui-button-alt-icon-size:2.5rem;--sd-ui-button-alt-min-width:5.5rem;-webkit-box-align:baseline;align-items:baseline;background-color:rgba(0, 0, 0, 0);border-style:none;box-sizing:border-box;color:var(--sd-ui-button-alt-colour);cursor:var(--sd-ui-button-alt-cursor);display:flex !important;font-family:inherit;font-size:var(--sd-ui-button-alt-font-size);gap:var(--sd-ui-button-alt-gap);line-height:var(--sd-ui-line-height);margin:0px;min-width:var(--sd-ui-button-alt-min-width);padding:0px;text-decoration:none;user-select:text;word-break:break-word;" href="https://www.sciencedirect.com/science/article/pii/S2212095524003079"><svg class="icon icon-navigate-left" style="-webkit-text-stroke-width:0px;color:rgb(31, 31, 31);font-family:ElsevierSans, Arial, Helvetica, Roboto, "Lucida Sans Unicode", "Microsoft Sans Serif", "Segoe UI Symbol", STIXGeneral, "Cambria Math", "Arial Unicode MS", sans-serif;font-size:16px;font-style:normal;font-variant-caps:normal;font-variant-ligatures:normal;font-weight:400;letter-spacing:normal;orphans:2;text-align:left;text-decoration-color:initial;text-decoration-style:initial;text-decoration-thickness:initial;text-indent:0px;text-transform:none;white-space:normal;widows:2;word-spacing:0px;" focusable="false" viewbox="0 0 54 128" height="20"><path d="M1 61l45-45 7 7-38 38 38 38-7 7z"></path></svg></a><br> </li></ul>
