Royal Raining making was initiated by King Bhumibol in year 1955. Since most Thai famers have to wait for seasonal rain to grow crops, they are at times faced with difficulties from drought, so there might not be enough rainfall for crop growing. His Majesty the King invented artificial rainmaking techniques by applying the new technology with the capacity of raining. The following data are the amount of rainfall (ml2) as a result of the project for the months or March and April 1956. The records are as following:

20 65 18 50 26 42 34 19 59 27 52 35 36 64 55 45 28 20 24 28 39 63 60 33 35 18 26 34 42 50 58 57 65 25 33 25 45 38
