Estimation of Moist Atmospheric Profiles from Refraction and Attenuation Measurements by Using Centimeter and Millimeter Wave Links between LEO Satellites

چکیده
Microwave occultation using centimeter and millimeter wave links between low Earth orbit (LEO) satellites provide a potential way to estimate the moist atmospheric profiles based on refraction attenuation measurements, which is called LEO-LEO microwave (LMO) technique. It has not yet been implemented in orbit. In this paper, we analyzed properties at different heights of waves simulations. The observing capabilities with frequency combinations X, K, M bands were analyzed. results show that LMO may improve retrieval accuracy bending angles above 35 km. By several appropriate frequencies X+K+M band, water vapor from near-surface lower stratosphere (~24 km) can be obtained. When M-band added, temperature does change obviously, but significantly 15 km, especially about 17–24 RMS errors decrease over 20% less 10%. For promoting mission real world, combination X+K band proposed, observe 2.5–50 km 2.5–15 accurately under clear cloudy conditions. This study demonstrates greatly extend radio technique our ability measure globally.

Atmospheric aerosol measurements from satellites
Satellite instruments are commonly used for measurements of aerosol optical properties in the atmosphere. In this work we use such measurements for ultra-high energy cosmic ray studies. We introduce a method of preparation of aerosol maps for the location of the Pierre Auger Observatory. For these maps the data from the Ozone Monitoring Instrument (OMI) of the Aura satellite were analyzed for t...
