Science Requirements

The goal of PATH is to answer several scientific questions related to hurricanes, storms, and climate. However, because PATH is still in the formulation stage, it's science goals are still evolving. Below is a list of preliminary science questions that the PATH mission is intending to answer.


How can we improve hurricane intensity observations?
  • Continuous monitoring
  • Measure warm core anomaly
  • Measure rain rate, convective intensity
  • Infer all-weather wind vector profiles

How can we improve understanding of storm dynamics?
  • GeoSTAR will mimic precipitation/cloud radar
  • Use to diagnose/fix model deficiencies
  • Initialize with current, complete state variables
  • Re-initialize with current observations

How can we improve understanding of continental storms?
  • Diurnal cycle fully resolved
  • Convection/rain measured in RT
  • Atmospheric stability measured concurrently

How can we improve understanding of hydrology cycle?
  • Diurnal cycle fully resolved
  • Convection/rain measured in RT
  • Moisture and clouds measured concurrently

How can weather forecast duration and reliability be improved?
  • Use observations to diagnose and fix model problems
  • Initialize with current, complete state variables
  • Re-initialize with current observations
  • Nudging and phase-correction/4DVAR
