This dialog box allows you to define climatology conditions, including: temperature; the evaporation that can occur for standing water on subcatchment surfaces, for subsurface water in groundwater aquifers, and from water held in storage units; wind speed data; snow melt; and areal depletion.

The dialog is divided into tabbed pages, where each page provides a separate editor for the following data categories (listed at the bottom of this page).

Access this dialog box by selecting Components > SWMM Extensions > Climatology.

The data shown in this dialog box is linked to the active Rainfall-Runoff Alternative, so differently climatology data can be used in different Scenarios.
