Impact Of a Single Observation from IASI


This test is a part of the H-8 AHI trial. As the weighting functions of IASI channels peak sharply the analysis increments can be better understood.

Experimental Set-up

Following set of configurations were used for this test,

  • 3DVAR
  • non-hybrid
  • Resolution of PFM is N216 - same resolution as screen 3DVAR
  • no VarBC

Note 1. The initial hybrid 4DVAR for AHI single-obs test was run at N108 PFM resolution. That needs to be done with N216 res.

Experiment was done using suite ID u-am568 (copy of u-aj730/trunk@40220),

  • ensemble and hybrid VAR are switched off
