MLS Research

Observations Needed To Improve Models

Contact Hui Su

Numerical models are the primary tools for weather forecast and climate change predictions. Accurate representation of processes involving water vapor, clouds and atmospheric composition has been a challenging problem in models for years.

Improvements of weather forecast and climate change predictions require extensive evaluation of model simulations by comparison with global satellite observations. The Aura MLS measurements of water vapor, clouds and other tracer gases provide a unique opportunity to evaluate model performance in the upper troposphere (~8-15km altitude) and to improve model parameterizations of key processes such as convection.
