Active Temperature, Ozone and Moisture Microwave Spectrometer (ATOMMS)

Development and testing of the Active Temperature, Ozone and Moisture Microwave Spectrometer (ATOMMS) cm and mm wavelength occultation instrument

We present initial results from testing a new remote sensing system called the Active Temperature, Ozone and Moisture Microwave Spectrometer (ATOMMS). ATOMMS is designed as a satellite-to-satellite occultation system for monitoring climate. We are developing the prototype instrument for an aircraft to aircraft occultation demonstration. Here we focus on field testing of the ATOMMS instrument, i...

The Active Temperature, Ozone and Moisture Microwave Spectrometer, A New Global Climate Sensor

Deriving atmospheric water vapor and ozone profiles from active microwave occultation measurements

The GPS/MET experiment was the first active atmospheric microwave occultation experiment using the existing GPS L1 and L2 frequencies to measure the atmospheric refractive index. One major limitation to this technique is that the presence of water vapor in amounts typically found in the lower troposphere (below 5-7 km) causes an ambiguity between the contributions of dry air and moisture to the...

An Active Microwave Limb Sounder for Profiling Water Vapor, Ozone, Temperature, Geopotential of Pressure Surfaces and Clouds

We present and characterize the performance of a new remote sensing concept extrapolated from the GPS occultation concept in which we choose the signal frequencies to determine profiles of atmospheric water, ozone, temperature, geopotential of atmospheric pressure surfaces and clouds.

Four-dimensional variational assimilation of ozone profiles from the Microwave Limb Sounder on the Aura satellite

[1] Ozone profiles from the Microwave Limb Sounder (MLS) onboard the Aura satellite of the NASA’s Earth Observing System (EOS) were experimentally added to the European Centre for Medium-range Weather Forecasts (ECMWF) four-dimensional variational (4D-var) data assimilation system of version CY30R1, in which total ozone columns from Scanning Imaging Absorption Spectrometer for Atmospheric CHart...
