The Portable Remote Imaging Spectrometer (PRISM) is an airborne push-broom spectrometer developed at Jet Propulsion Laboratory (JPL). PRISM was designed to provide the necessary spectral, spatial, and temporal resolution to characterize events in coastal zones that satellite observations cannot offer. 

The spectrometer within PRISM operates in the near-ultraviolet to near-infrared range (350-1050 nm) to capture imagery over coastal ocean regions. PRISM also includes a two-channel radiometer operating in the shortwave infrared (1240 and 1640 nm) wavelengths to deliver accurate ocean color measurements. It features a high temporal resolution (167 Hz) and can fly below cloud cover at various altitudes, enabling it to resolve spatial features down to 30 cm.
