| Zusammenfassung |
Atmospheric sounding using the Global Navigation Satellite Systems (GNSS) is
a well-established research field in Europe. At present, GNSS data from 1800
stations are available for model validation and assimilation in
state-of-the-art models used for operational numerical weather prediction
centres in Europe. Advances in GNSS data processing make it possible also to
use the GNSS data for climatic trend analysis, an emerging new application.
In Bulgaria and southeastern Europe, the use of GNSS for atmospheric sounding
is currently under development.
As a first step, the Sofia University Atmospheric Data Archive (SUADA) is
developed. SUADA is a user-friendly database, and includes GNSS tropospheric
products like zenith total delay (ZTD) and derivatives like vertically
integrated water vapour (IWV), as well as observations from radiosonde (RS)
and surface atmospheric data. Archived in SUADA are (1) GNSS tropospheric
products (over 12 000 000 individual observations) and derivatives (over
55 000) from five GNSS processing strategies and 37 stations for the period
1997–2013, with temporal resolutions from 5 min to 6 h, and (2) radiosonde
IWV data (over 6000 observations) for station Sofia (1999–2012).
Presented are two applications of the SUADA data for the study of long- and
short-term variations of IWV over Bulgaria during the 2007 heatwave and
intense precipitation events in 2012. |
