• Title: Thailand Applied Atmospheric Research Program - Final Report - Volume I
• Prepared For: US Agency for International Development
• Date: 3/1/1994
• Country: Thailand
• Weather Modification - Doc Type: Report

As a result of critical delays in the implementation ofthe project, Amendment 6 to the PASA
was executed in December 1989, by which the Project Implementation Plan and Project Goal
were changed. The new goal of the project became:

"The goal of the program is to provide the Royal Thai Govemment with the
capability to conduct a scientifically sound demonstration project to quantify
the water augmentation potential of rainmaking in Thailand. The program
involves the development of a design and operations plan for the rainmaking
demonstration project and the provision of equipment and training to permit
its subsequent execution by Thai personneL"

On October 23, 1991, the AARRP PASA was suspended in accordance with the suspension
of U.S. economic assistance to Thailand until a democratically elected govemment was
restored to Thailand. The PASA was reinstated on November 1, 1992, by PASA Amendment
8, which made further changes to the Project Implementation Plan and Project Goal. The
new and final goal of the project was:

"The goal of the program is to provide the Royal Thai Govemment with the
capability to conduct a scientifically-sound demonstration project to quantify
the water augmentation potential of rainmaking in Thailand. The program
involves the conduct of field research and studies leading to the development
of a design and operations plan for the rainmaking demonstration project, and
the provision of equipment and training to plan and carry out the
demonstration project."

Therefore, the AARRP focused on theoretical studies and randomized exploratory experiments
to determine which of the physically plausible warm and cold cloud seeding concepts warrant
further testing, and the design of a follow-on project (AARRP Phase 2) to demonstrate their
feasibility. The goal of AARRP Phase 2 is to quantify the water augmentation potential of
promising rainmaking techniques identified under the AARRP (Phase 1) through proof-of-
concept experiments in a demonstration project.

It is important to note that, although PASA Amendment 8 further relaxed the Project Goal,
the PASA succeeded in accomplishing the design and operations plan for a warm and cold
cloud seeding demonstration project as called for in P ASA Amendment 6. This
accomplishment was made possible by the dedicated, diligent, and cooperative efforts of
AARRP scientists from Thailand, and from Reclamation and its contractor, Woodley Weather
Consultants.

This final report under the PASA consists of three volumes. Volume 1 includes a summary
of the AARRP structure, the contributions to the AARRP by the U.S. and the Royal Thai
Govemments, and the institutional development, technology transfer, technical, and scientific
accomplishments. Volume 1 concludes with a summary of problems encountered, lessons
leamed, and recommendations for the future. Volume 2 presents a detailed account of the
scientific studies and their findings, and provides the design of the demonstration project
(also known as AARRP Phase 2). Volume 3 presents the operations plan for the
demonstration project.
