In a novel application of space - based atmospheric measurements, Atmospheric and Environmental Research (AER), in collaboration with GeoOptics Inc., is investigating the use of
radio occultation measurements to improve severe weather forecasting.
Space - based GNSS
radio occultation measurements onboard satellites such as CHAMP, GRACE, and Formosat3 / COSMIC are well suited to detect such ionization enhancements in the bottomside ionosphere.
To evaluate the reliability of
radio occultation measurements and to study precipitation processes in more detail, coordinated EISCAT measurements would be useful.
Due to the high value of
radio occultation measurements for monitoring the current tropospheric weather conditions, a follow on mission of COSMIC / Formosat is planned which will provide a huge database for ionosphere sounding.
Using
radio occultation measurement to reconstruct the electron density profiles in the E region, Mayer & Jakowski (2009) have collected cases when the maximum density of the E region exceeds that of the F2 - layer.
