Overview

Climate and weather predictions could be improved by microwave science data from instruments like GeoSTAR. Currently, our understanding of cloud formation, convection, and precipitation is not completely understood. In prediction models, "microphysics" are often deficient. Additionally, diurnal-cycle variations and storm life cycles are not well modeled. Below is a list of science questions that researchers are currently considering to help them discover what gaps there are in our data collections and how new instruments could measure them.

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

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

Science question: 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

Can use continuous observations of "process measures" in stormy areas: rain, clouds, stability? These observations could be provided by GeoSTAR
