Multispectral Weather Satellite Channels

Modern weather satellites image the same scene simultaneously across many wavelength bands, and each band reveals different physics. This simulator generates one rotating storm system and lets you switch the imaging channel: Visible shows only cloud shape and brightness; Infrared recolors the identical clouds by cloud-top temperature, separating dangerous cold high storm tops from harmless warm low cloud that looks the same in Visible; Water Vapor reveals a moisture field invisible in both other channels, including over clear sky. Click any point on the globe to compare all three readings side by side.
