RO Team1 pan lev6 by SysSonProject published on 2012/03/01 09:39:05 +0000 We provide two radio occultation (RO) data sets. The RO method is a remote sensing technique making use of GPS signals to retrieve atmospheric parameters (refractivity, pressure, geopotential height, temperature) in the upper troposphere-lower stratosphere (UTLS), which we define as region between around 5km and 35km height. Temperature and refractivity data are provided. Refractivity can be thought of as atmospheric density and is approximately indirectly proportional to temperature. The data are provided from the Wegener Center for Climate and Global Change, University of Graz. The sonification shall allow hearing the QBO (Quasi biennial oscillation), a stratospheric pattern of changing temperatures (wind directions), best pronounced in the tropics (10°N–10°S). An extra-tropical QBO signal can be probably found at higher latitudes with a different phase.
