Web-based RainyDay (Basic)
This basic version will generate 10 realizations of 500-Year rainfall scenarios.
1. Define the duration of rainfall accumulation period in hours.
2. Define the SST Domain and Catchment

4. Run RainyDay simulation.

1. Define Simulation Mode (we recommend starting with a diagnostic run).

Diagnostic Run
2. Define rainfall input dataset.

3-1. Define the duration of rainfall accumulation period in hours.
3-2. Define how many storms to include in the process (we recommend at least 5 times the length of the input dataset in years).
3-3. Define the maximum return period you want computed (example: 500).
3-4. Define how many years of long sequences to be generated.
3-5. Define the minimum separation time in hours between two storms in the storm catalog (We recommend at least 24 hours).
3-6. Define the minimum return period for which a spacetime rainfall scenario will be written.
3-7. Return Levels.Specify certain return periods for which you want to produce output scenarios and frequency analyses.
Default - (Return Period: 1, 2, 5, 10, 20, 50, 100,1000)
All years
4. Print Diagnostic Plots? ( Create diagnostic plots in JPG format. )
YES
NO
5-1. Define months (1-2 digit numeric) to be excluded from the storm catalog creation.
(Months must be comma separated.)
5-2. Define start and end year.
5-3. Which storms, if any, to exclude. To exclude certain storms that are part of the storm catalog but which you do not
wish to include in subsequent frequency analysis or spacetime rainfall scenarios.
This is useful if a diagnostic run has revealed that there are unrealistic radar artifacts in certain storms.
6-1. Define how the spatial transposition should be done.
UNIFORM
NONUNIFORM
6-2. Define the method used for generating the number of storms to be transposed for each synthetic "year".
POISSON
EMPIRICAL
7. Define the boundaries of the Transposition Domain.

9. Rainfall Intensity Sensitivity Analysis.
YES
For example, an input of 5.0 means that the intensity of rainfall will be increased by 5%.
NO
10. Rainfall Frequency Sensitivity Analysis. If "YES", Field 6-2 must be set to "POISSON".
YES
For example, an input of -15.0 means that the rate of storm occurrences will be reduced by 15%.
NO
