The project has proved successful since the first experiment in 1969. In 1971, the Government established the Artificial Rainmaking Research and Development Project within the Ministry of Agriculture and Cooperatives. Since demand for artificial rain has increased over the years, the Artificial Rainmaking Research and Development Project has been continuously upgraded and developed.
In 1999, HM King Bhumibol discovered a new technique to gain more cloud density to increase the amount and extent of rainfall. He named the new cloud-seeding technique "Super Sandwich". More new techniques are being discovered and introduced to the people involved. His Majesty's ingenuity for inventing the rainmaking technology has been widely recognized and has made Thailand the centre of tropical rainmaking activities in this region.
