### Method for Working out the Cost Estimates of Data

#### 1.    Cost of Daily Surface Data for 10 Stations for 3 Years

 No. of Records for 1 station per year =1095 (3 x 365) Recs x Stns x Yrs = Total Records. = 1095 x 10 x 3 = 32, 850 Recs. =Rs. 172463/- ( Rs 8623/- = 172463 x 5%, in case of Research Students/Academic Institutes etc.) = Rs. 10466/- (32900 x 0.29 + 925 as per Instruction manual) =Rs. 60/- =Rs. 1,82,989/- =Rs. 26,533/- = Rs. 2,09,522/-

#### 2.    Cost of Monthly Mean Surface Data for 10 Stations for 5 Years

No. of records for 1 station per year =3 x 12 = 36 Records. RecsxStns.xYrs. =36x10x 5 = 1800 Recs. =Rs. 47,250/- (47,250/- x 5% = Rs 2363/- For Research Purpose) = Rs.1,447/- (1800 x 0.29 + 925) =Rs. 60/- =Rs. 48,757/- =Rs. 7,070/- = Rs. 55,827/-

#### 3.     Cost of Daily Rainfall Data for 10 Stations for 20 Years

 Recs x stns x Yrs. = (24 x 20 x 10) = 4800 Records = Rs. 1,14,000/- (Rs. 1,14,000 x 5% = Rs 7200/- for Research Purpose) = Rs. 2,317/- (4800 x 0.29 + 925) = Rs. 60/- = Rs. 1,46,377/- = Rs. 21,225/- = Rs. 1,67,602/-
Ā

#### 4.     Cost of Monthly Rainfall Data for 15 Stations for 30 Years

No. of records for 1 station per year = 2 Recs xStns x Yrs. = 2 x 15 x 30) = 900 = Rs 54,000/- (54000 x 5% = Rs 2700/- for Research purpose) = Rs. 1,186/- = Rs . 60/- = Rs. 55,246/- = Rs. 8,011/- = Rs.63,257/-
