Describe the New Feature

The Stable Equitable Error in Probability Space (SEEPS) score is described in Rodwell et al. (2010) and was devised for evaluating quantitative precipitation forecasts against SYNOP gauge data at (but not limited to) station locations. It uses a climatology to account for local variations in rainfall which enables aggregation over otherwise heterogenous locations.

This issue will detail the work required to implement this capability within MET and to act as an umbrella issue to log progress as it is likely that implementing this will require division into further sub-issues.

Changes will be required to Point-Stat in order to compute the score.
Support for a point-based climatology will be required. MET #1941 has been opened for the work required for this capability.

This issue will supersede the SEEPS portion of MET #563.

This still needs more definition on how to implement.

The tasks for this work include:

• Enhance Point-Stat to compute SEEPS.
• Enhance Stat-Analysis to compute SEEPS from the matched pair (MPR) input lines.

There is no way to mathematically aggregate SEEPS over multiple runs. Instead we just compute the mean of the SEEPS over multiple runs.

We do still need to define the columns that should be included in a new SEEPS line type.

Acceptance Testing

List input data types and sources.
Input data expected to be either ASCII text or NetCDF files.
Original IDL code can be provided to compare scores. Example C code is provided in the google drive link at #563 (comment)
