Active Temperature Ozone and Moisture Microwave Spectrometer (ATOMMS)
STATUS
Research Prototype
AVAILABILITY
We are presently building the prototype ATOMMS instrumentation for a series of WB57F high altitude aircraft to aircraft occultation demonstrations in 2010. As of October 2009, we are performing ground tests of the instrument performance. This effort is funded by an NSF Major Research Instrumentation (MRI) grant. NASA is providing the aircraft time.

ATOMMS is a cm and mm wavelength occultation system representing a natural evolutionary step following GPS radio occultations (GPSRO). ATOMMS is essentially a cross between GPSRO and the Microwave Limb Sounder (MLS). For ATOMMS, we probe the atmosphere via satellite to satellite occultations at wavelengths chosen near absorption lines of water (22 and 183 GHz), ozone (184 and 195 GHz) and other species. Its advantages over GPSRO are (1) by simultaneously measuring both bending and absorption it simultaneously provides separate temperature and water vapor profiles directly without any additional constraints, (2) it provides the dynamic range to profile water vapor from near the surface to the mesopause providing water to a few % accuracy and sub-kelvin accuracy with ~200 m vertical resolution in clear and cloudy air (3) its short wavelengths reduce sensitivity to the ionosphere by four orders of magnitude which allow water and temperature profiles to extend to the mesopause. ATOMMS capabilities are particularly well suited to addressing the many questions about the UTLS. ATOMMS can also profile water isotopes and turbulence.
