Melting Height Config

The Melting Height Config setting allows users to configure the estimated melting layer height for each month of the year. The melting layer, also known as the bright band, is a critical feature in radar meteorology used to enhance the accuracy of precipitation classification and quantitative precipitation estimation (QPE). By providing monthly values, the radar can adjust its algorithms to seasonal variations in the atmosphere.

Accessing Melting Height Config

To configure the melting height:

  1. Navigate to the Radar Control panel.
  2. Select Configure Settings from the dropdown menu.
  3. Choose Melting Height Config from the available options.

Configuration Interface

Upon selection, a configuration panel will appear containing:

Monthly Fields

There are individual input fields for each month of the year, from January to December.

  • Unit: Meters (m)
  • Requirement: Enter the estimated melting layer height in meters for each month.
  • Example:
  • January: 1050
  • February: 1000
  • March: 1500
  • April: 2000
  • May: 2500
  • June: 3000
  • July: 3500
  • August: 3500
  • September: 3000
  • October: 2500
  • November: 1500
  • December: 1000

Upload Button

Once all fields are completed, click the Upload button to save and apply the settings.

Note: Ensure all 12 fields are filled with valid numeric values before uploading.

Best Practices

  • Data Source: Use climatological data, model estimates, or local observations to determine appropriate melting heights.
  • Review Annually: It is recommended to review and update the melting height configuration at least once per year to reflect any climatological changes.
  • Impact on Radar Products: Adjusting melting height can improve the accuracy of precipitation type detection and QPE, especially during transitional seasons.

Troubleshooting

  • Invalid Input: Ensure all fields contain numeric values in meters. The system will prompt an error if any field is empty or contains invalid data.
  • Configuration Not Applied: After clicking the Upload button, confirm that the system indicates a successful upload. If not, re-check the fields and try again.
