Impact of Satellite Observations on NWP
Introduction:
This lesson covers how satellite observations inform numerical weather prediction models. It begins with a basic overview of what satellite data types are assimilated and how, and ends with an overview of how data from new instrument’s may make it into a model.This lesson is a part of the NWS Satellite Foundational Course for GOES-R.More in-depth discussions and a quiz on the impacts of satellite observations on NWP can be found in the COMET lesson, How Satellite Observations Impact NWP.
Objectives:
- Describe the impact of satellite observations on NWP model analyses and forecasts
- Identify the primary types of environmental satellites that provide observations to data assimilation (DA) systems and NWP models
- Describe how observations from new satellite instruments are vetted for use in DA systems
- Describe the process of assimilating satellite observations and retrievals once they have been accepted for use in DA systems.
