Deterministic models assimilating RO
- Global model:
- T574
- 64 vertical levels
- 4 cycles per day
Data assimilation method
- Global model:
- Hybrid 3dvar, 3hr assimilation window
- Regional model (NAM):
RO quantity assimilated
- Bending angle
- 1D operator
- Tangent point drift included
- No vertical thinning
- No bias correction
Observation error characteristics
- These are tuned taking into account the representativeness error associated to our model
