| RAIN_M | end-time, m | An array of values, each pair indicating until what time that period of rain will last and how much rain will fall in that period. |
How to manually adjust the RAIN_M attribute:
- In the Water Overlay select Keys.
- Click on "Edit" next to where it says "Weather:".
- Select Attributes.
- Add or remove values from the RAIN_M array.
Single rain value to Rain Array
When only one value is provided, it will be internally converted to a rain array. The single value then represents the amount of rain, and the default rain duration is 7200 seconds (2 hours).
For example: when a weather has a rain attribute defined with a value of 0.040 (m), it is converted to the array: 7200 0.040. This means that a total of 0.04 m (40 mm) of rain will fall, evenly spread over 7200 seconds (2 hours).
When you want the rain to fall in a shorter time period, for example the first hour, you would have to write: 3600 0.04 Also note that you can delay the rain , with for example 1200 0 3600 0.04, where the first 20 minutes no rain will fall and in the 40 minutes after it, 40 mm will fall.
