Abstract
The high-performance PostgreSQL database (GOP-TropDB) capable to deal with billions of data records has been developed at the Geodetic Observatory Pecný (GOP) for monitoring tropospheric parameters from various sources – space geodetic techniques (GNSS, VLBI, DORIS), observations (radio sounding, water vapour radiometers, in-situ measurements) and meteorological products from numerical weather models. This paper describes initial motivations and functionalities, basic database structure supporting various data sources and optimization for huge data sets. Initial database exploitations and outputs are demonstrated together with discussion on foreseen developments. Recently, we targeted implementations in support of a routine intra-technique tropospheric product evaluation and monitoring within the Tropospheric working group of the International GNSS Service (IGS). The inter-technique comparisons with tropospheric products available from the International DORIS Service and the International VLBI Service for Geodesy and Astrometry of the International Association of Geodesy were implemented too.
