National Weather Service Hilo, National Climatic Data Center

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 recorded on standard government forms and the equipment is reset for the next 24 hour reading or observation.

• 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.

Our cooperative program is a volunteer program involving the daily measurements of rainfall and temperature. The recorded data are sent to the National Climatic Data Center where they are archived as official government documents and produced as monthly publications.

The National Climatic Data Center in Asheville, N. C. archives the data and as one of its missions, does research on long-term climatic changes which involve climatic trends.

Same as above.

The true worth and importance of this program lies in its long historical and practical values. The cooperative program has proven its worth and can attest to a taxpayer savings of millions of dollars annually.
