RUC Collaboration

To Do List

This document contains the current To Do List for the NCAR/FSL RUC collaboration.

Current To Do List
Status Priority Assigned To Description
In progress High Nancy Put together a system to retrieve the experimental RUC grids from the FSL FTP site.

rucRetrieveExp has been written and is installed on storm to do the file retrieval. This is currently running hourly on storm, even though the experimental grids seem to be generated on 3-hour intervals. The raw RUC files were added to the daily backup and scrubbing scripts on storm.

Still need to add a rucIngest process to storm so that the data will be available for display. I need to talk to Dan about how we should restructure storm so that we can more easily add things to the system.

In progress Medium Nancy Write rucHybrid2Pressure so that we can run our systems using just the hybrid grids.

I've started working on this as a lower priority task. The basic conversion code has been converted from FORTRAN to C++, but hasn't been tested.

Medium Write a program that will compute a gridded field from the radar mosaic that represents what we are trying to predict with the RUC forecasts. This program will look at the radar mosaic data distribution within a 40 or 80 km box (parameter) and calculate fields like:
  • number of grid points over a given threshold
  • mean (probably not that useful)
  • highest data value
  • lowest data value
  • 75th (parameter) percentile data value
  • spread
  • standard deviation
There are two possibilities for this processing:
  • Define an output grid in the parameter file (probably matching the RUC grid or something like that) and do the calculations within each output grid square
  • Pass a template (square or circular) over each grid point in the input grid and do the calculations at the resolution of the input grid. X and Y step values could be added in this case to give you something like the above option, but allowing overlap at the edges of the calculations.
