What does this program measure?

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.


How does this program work?

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.


Why is this research important?

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.


Are there any trends in the data?

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.

What is it's role in global climate change?
