This module introduces forecasters to the use of microwave image products for observing and analyzing tropical cyclones. Microwave data from polar-orbiting satellites is crucial to today’s operational forecasters, and particularly for those with maritime forecasting responsibilities where in situ observations are sparse. This module includes information on storm structure and techniques for improved storm positioning using the 37 and 85-91 GHz channels from several satellite sensors. Information on current sensors and on the product availability in the NPOESS era is also presented.
Explain how single channel and multispectral microwave imagery can be used to locate centers of circulation and other features within tropical cyclones
Explain how parallax error affects imagery from different microwave channels
Identify satellites that carry microwave imagers and sounders
Contrast active and passive microwave remote sensing strategies
Contrast conical and cross-track scanning strategies
Explain how clouds, precipitation, and the ocean surface interact with microwave
energy at different frequencies
Associate storm characteristics with features observed in microwave imagery
