Technical Meeting on a Radar Composite Map for Thailand
Tokyo, Japan, 25 – 28 November 2014

The ESCAP/WMO Typhoon Committee (TC) promotes the development of a regional radar network covering Southeast Asia. To support this goal, JMA held a radar composite map technical meeting at its headquarters from 25 to 28 November 2014 with two invited experts from the Thai Meteorological Department (TMD).

During the meeting, JMA experts gave a series of presentations covering information necessary for the creation of a high-quality radar composite map, such as methodical quality management and statistical quality control. As a result of the practical training in quality control provided at this meeting, TMD experts were able to improve radar data quality in their nationwide composite map.

Presentations on quantitative precipitation estimation (QPE) focused on a two-dimensional calibration method applied to radar monitoring based on rain gauge observations. Typical cases of quality deterioration in QPE were also highlighted.
  The attendees further discussed the implementation of quality management in TMD radar operation and ideas for QPE development in TMD.
