Meaning of hofx0, hofx1, hofx2 after MPAS-JEDI bias correction

JEDI
1

After I ran the satellite bias correction, the output file obsout_3denvar_bc_amsua_n19.nc4contains hofx0, hofx1, hofx2in hofx, and EffectiveQC0, EffectiveQC1, EffectiveQC2in EffectiveQC.

  1. I would like to confirm my understanding: do the values 0, 1, and 2 represent the results at each iteration? In that case, should ObsValue - hofx0correspond to ombg, and ObsValue - hofx2correspond to oman?

  2. How can I find the specific value of the bias correction, i.e., [y - hx - B(β)]? I want to see the situation before and after the correction.

  3. What is the role of the ObsBias group? Is it related to the bias correction?

Thanks!
