SUADA: Sofia University Atmospheric Data Archive

The Sofia University Atmospheric Data Archive (SUADA, http://suada.phys.uni-sofia.bg/) has been developed to provide a framework for archiving Bulgarian atmospheric data on an ongoing basis. Currently, SUADA includes water vapour, derived from tropspheric path delay, at 31 ground based stations of Global Navigation Satellite Systems (GNSS) network in Bulgaria as well as IGS repro1, repro2 and radiosonde data for station Sofia. The envisaged applications of the SUADA include: (1) cross-validation of ground-based and satellite observations and derivation of systematic biases; (2) study of the 2D water vapour distribution in Bulgaria/Southeast Europe; (3) study convective storms development in Bulgaria/Southeast Europe; (4) detection of long term water vapour trends in Bulgaria/Southeast Europe and links to heat waves, droughts and changes in the pathway of the Atlantic Cyclones.
