National Weather Service Honolulu Forecast Office

The Max/Min Temperature Unit records 24 hour Maximum/Minimum temperatures in degrees Fahrenheit. The Standard Rain gauge records 24 hour rainfall in hundreds of an inch.

The data is measured manually by MLO personnel and and relayed to the Honolulu Forecast office by telephone through the ROSA system.

• A 20-cm rain gauge is recorded 5 times per week at MLO.
• A 20-cm rain gauge is recorded 1 time per week at Kulani Mauka.
• A rain gauge and tipping bucket are measured continuously at MLO.

The temperature and rainfall data are transmitted daily via telephone to the Honolulu Forecast office through a network called PRONET which is entered in the AWIPS computer bank to be used as a forecasting aid.

The data are used by the Forecast Office as a guide in updating their forecast. The data are mainly used as “real time” data.

Same as above.
