Subject: NSA/MWRRET/C1 - Sonde input processing issue
Affected Datastreams: nsamwrret1liljclouC1.c1
Description There was a data processing issue with the nsasondewnpnC1.b1 datastream during these periods. As a result, the nsamwrret1liljclouC1.c1 files were sometimes processed without any sonde data available as an input to the VAP. The physical retrievals, phys_lwp and phys_pwv, require sounding data and were not calculated for these files. This also means that the be_lwp and be_pwv from these files only contain values from stat2_lwp and stat2_pwv.
Measurements
  • phys_pwv (Precipitable water vapor retrieved using a physical/iterative approach)
  • phys_pwv_uncertainty (1-sigma uncertainty in precipitable water vapor retrieved using a physical/iterative approach)
  • phys_lwp_uncertainty (1-sigma uncertainty in cloud liquid water path retrieved using a physical/iterative approach)
  • phys_converge (Convergence value for the physical retrieval)
  • phys_rms (Root mean square difference between the computed and observed brightness temperatures for the last iteration)
  • phys_niter (Number of iterations needed by the physical retrieval for convergence)
  • phys_lwp (Cloud liquid water path retrieved using a physical/iterative approach)

Subject: NSA/MWRRET/C1 - Reprocess: Updated to use static offsets for consistency
Affected Datastreams: nsamwrret1liljclouC1.c2
Description A slight change in values of offset (vbias_31) results in small changes in retrieval variables. Updated data values to use static offsets that were created based on the entire for consistency.
