TPW over ocean

• “Grandfather” of MW products

  • Most accurate MW product: RMS ~10%
  • Generated since 1970’s (research)

• TPW “signal” comes from 22 GHz region

  • SSM/I near center (22.235 GHz)
    • saturation at high TPW’s
  • AMSU off center (23.8)
    • no saturation, but limb affects

• Utilize other channels to remove Q effects

  • SSM/I: 19 and/or 37 GHz
  • AMSU: 31.4 and/or 50.3 GHz
