A DSS Grid Record Validator utility was added to help modelers identify issues within their gridded boundary conditions (e.g. precipitation, temperature, SWE, etc) that would prevent a simulation from successfully completing. 

Requirements for gridded datasets include:

  • number of rows and number of columns remain constant throughout the simulation,
  • lower left corner coordinates remain constant throughout the simulation,
  • projection (e.g. SHG) remains constant throughout the simulation, and
  • grid cell size remains constant throughout the simulation.

Additionally the grid record validator validates each grid record based on the grid type specified. Record requirements are specified in Grid Data and include:

  • valid data type (e.g. PER-CUM, INST-VAL),
  • valid C-Part,
  • valid units, and
  • valid start and end times.

This utility can be launched from the Grid Data Manager or by right clicking the Gridset of interest and selecting Validate, as shown in the following image.

Validating a Precipitation Gridset

The utility will loop over all records contained within the referenced DSS file and check for issues like those noted above.  If any issues are encountered, error messages will be shown informing the user, as shown in the following image.
