The rainfall data can be either a user-defined time series or come from an external file. Several different popular rainfall file formats currently in use are supported, as well as a standard user-defined format. The principal input properties of rain gages include: rainfall data type (e.g., intensity, volume, or cumulative volume)

The standard way of measuring rainfall or snowfall is the standard rain gauge, which can be found in 10 cm (3.9 in) plastic and 20 cm (7.9 in) metal varieties. [83] The inner cylinder is filled by 2.5 cm (0.98 in) of rain, with overflow flowing into the outer cylinder.
Here are rainfall amounts, in inches, from the last 24 hours (unless otherwise noted) by locality, according to National Weather Service St. Louis: Illinois locations Belleville: 6.23, 6.33
Find the depth of rainfall from a storm of duration 6 hours and return period 10 years on a catchment of 5 km 2 in Sheffield. From the FSR maps, the M5-60 minutes rainfall is 20.5mm, and "r" = 0.4. Divide 20.5mm by 0.4 to get 51.3mm, which is the M5-2 days rainfall depth. Factor Z1 = 0.64, so multiply 51.3mm by 0.64 to get 32.8mm.
Rainfall forecasts can be verified a number of ways. Rain gauge observations can be gridded into areal averages, which are then compared to the grids for the forecast models. Weather radar estimates can be used outright, or corrected for rain gauge observations. [4] Several statistical scores can be based on the observed and forecast fields.
