2nd International GPM Ground Validation Workshop
[27 - 29 September 2005; Taipei, Taiwan]
In 2005 the 2nd International GPM Ground Validation Meeting was hosted by the National Taiwan University at Central Weather Bureau (CWB) in Taipei, Taiwan. The meeting also included a visit to CWB Observation Station in Hualien. The workshop was a great success thanks to the hosts and those who participated.
