Save Data

This selection allows the user to save the viewed scenario as an ASCII data file. Save data may only be chosen after the scenario field has been viewed using View Map. The user will be asked to define a root name (maximum eight characters) for the ASCII data files which will be created. The user will then be able to choose which variables to save. Only those variables for which data exist for *all* the current selection of GCMs will be displayed for saving. A separate default filename extension will be created for each requested variable.

It is also possible to save data for only part of the viewed image. Move the mouse on the map to the top left corner of the segment to be saved and drag the cursor down to the bottom left corner. The selected area will then be highlighted on the map. When Save Data is implemented, then only values for this chosen region are written to file.

All months, seasons and the annual values are saved irrespective of which month/season is displayed by SCENGEN on screen. The data files will contain some header lines of information about the scenario and then one line of data for each pixel (5 deg or 0.5 deg) in the field. The data are saved to the first decimal place ( e.g. 10.4 ). Missing values (i.e., actual values over ocean areas) are written as -999.0 (this is because the baseline climatologies only cover land areas). Saving this information may take up to 60 seconds.

The created files will appear in the /output sub-directory under the main /scengen directory.
