<DIV STYLE="text-align:Left;"><P STYLE="font-size:16ptmargin:0 0 11 0;"><SPAN>The FFRA_Index was developed for a 30-county area at 1×1 km resolution to balance computational efficiency and clarity of intent; designed to identify areas warranting outdoor warning sirens, not to site sirens directly.</SPAN></P><P STYLE="font-size:16ptmargin:0 0 11 0;"><SPAN>The FFRA_Index is provided for the 30-county area at a spatial resolution of 1-kilometer by 1-kilometer for better computational efficiency as well as to align with input data with the coarsest resolution among those that were used in this study. In addition, the selection of the 1-kilometer by 1-kilometer grid for processing FFRA can avoid confusion about the intent of the product – a finer resolution may give a false impression about the precision or intent of this study. This study is not intended to site sirens as part of outdoor warning siren systems but to identify flash flood-prone areas that warrant sirens. FFRA with a resolution of 1x1 kilometer can adequately serve as foundational information for identifying flash flood-prone areas that warrant sirens given the audible radius for outdoor warning sirens typically ranging from approximately 1 to 2 miles.</SPAN></P></DIV> |
