Rainfall Over Ocean
Utilize both emission and scattering signatures of rainfall
- Emission: 19-37 GHz/Scattering: 85+ GHz
Rain identification:
- Emission:
- CLW (Q) cloud/rain threshold (0.2-0.3 mm)
- Function of freezing level, cloud base, etc.
- Operational algorithm for SSM/I and AMSU use static threshold (for now)
- AMSU-Limb Affects
- Scattering:
- Scattering “Index” (ice phase/falling snow)
- Remove sea-ice signature
