The sub-daily precipitation data table is used to store the sub-daily precipitation for an
individual rain gage. This table is required if the raingage option is chosen for rainfall in
the weather data dialog box. There will be one precipitation data table for every location
listed in the rain gage location table.
The name of the precipitation data table is "name.txt" where name is the character
string entered for NAME in the rain gage location table.
This table must be formatted as an ASCII text (.txt) table.
Note: The interval between precipitation measurements must be equal throughout the
entire period of record. For example, all precipitation measurements must represent
hourly totals. A maximum of 878,400 sub-daily records per station are allowed.
