JPL SAW
JPL Surface Acoustic Wave Hygrometer

The JPL Surface Acoustic Wave (SAW) Hygrometer is an in situ airborne microhygrometer developed by the Jet Propulsion Laboratory (JPL). It uses a SAW device to detect condensation for dewpoint or frostpoint temperature measurements. The JPL SAW hygrometer is two orders of magnitude more sensitive to condensation compared to chilled-mirror hygrometers, allowing for a faster response to humidity changes. JPL SAW Hygrometer has a temporal resolution of up to 0.1 seconds.
