 Many models require time dependent data such as temperature, release rates and precipitation.

-  * **Interpolation-Extrapolation** – Values between the specified time-points are linearly interpolated. Values before the first time point and after the last time-point will be extrapolated. +  * **Linear** – Values between the specified time-points are linearly interpolated. 
-  * **Interpolation-Use end values** – Values between the specified time-points are linearly interpolated. The value for the first time point will be used when time is less than the first time point. The value for the last time point will be used when time is larger than the last time point. +  * **None** – Time-points will not be presented in a form of a step function.
-  * **Use input nearest** – For each simulation time point the value for the nearest specified time is used. +
-  * **Use input below** – For each simulation time point the value for the nearest of the lower specified time points is used. If none of the specified time points is lower, then the nearest of all specified time points is used. +

-**Cyclic** - When selected the time series will be “looped” and all values repeated. This feature is useful for periodic data, for instance one year dayly data of precipitation.

 For small data sets, the easiest way is to enter the data directly in the table. For large data set, the easiest way is typically to import it (see [[import|below]]). For small data sets, the easiest way is to enter the data directly in the table.

Line 45: Line 53:
 When you enter data for a multidimensional time series, such as a release rate of contaminants, there is a column for each index (contaminant). If you wish to assign the same data for several contaminants, you can put it in the default column. A value set in the default column will be used for all indices, but can be overridden by entering values in the subsequent columns. When you enter data for a multidimensional time series, such as a release rate of contaminants, there is a column for each index (contaminant).
