- | ==== Information | + | ==== Data ==== |
- | The information section details specifics about the time series. The description box can give you information about the data to enter, and the unit box tells you which unit is expected for the data. | + | The **Data** field in the **Values** tab is used to assign values to time-dependent |

- | **Interpolation** - The interpolation field will determine how values before, between and after the time-points are interpolated/ | + | ==== Options ==== |
- | * **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. | ||
- | * **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. | ||
- | * **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. | ||
- | * **Use input above** – For each simulation time point the value for the nearest of the higher specified time points is used. If none of the specified time points is higher, 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. Note that for cyclic lookup tables the final value(s) must be the same as the first value(s). | ||

- | Note that time series typically begin at 0. This means, that for year 1, you enter 0. For year 2 you enter 1, etc. | + | The data table is organized with the time points in the first column and data in the subsequent column(s). For scalar data, such as temperature or precipitation, data is put in the //default// column. The chart below the table will display the data as you enter it. |
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.
