Describe the New Use Case

Compute and plot space-time cross-spectra for S2S forecasts

Use Case Name and Category

UserScript_fcstS2S_obsERAI_CrossSpectra.conf
category: s2s

Input Data

Input files are netcdf format for precipitation and zonal wind at 850hPa and 200hPa:
35M prate_avg_ufs_p5_2014040100.nc - UFS prototype 5 6-hourly average precipitation rate
35M prate_avg_ufs_p7_2014040100.nc - UFS prototype 7 6-hourly average precipitation rate
546M precip.erai.sfc.1p0.2x.2014-2016.nc - ERA Interim 6-hourly average precipitation rate
36M u200_ufs_p5_2014040100.nc - UFS prototype 5 6-hourly zonal wind at 200hPa
36M u200_ufs_p7_2014040100.nc - UFS prototype 7 6-hourly zonal wind at 200hPa
36M u850_ufs_p5_2014040100.nc - UFS prototype 5 6-hourly zonal wind at 850hPa
36M u850_ufs_p7_2014040100.nc - UFS prototype 7 6-hourly zonal wind at 850hPa
total input size: 760MB

Acceptance Testing

Describe tests required for new functionality.
As use case develops, provide a run time here
Run without error and output spectra netcdf files and plots

Time Estimate
