3. 12th EMS Annual Meeting & 9th European Conference on Applied Climatology (ECAC) | 10 – 14 September 2012 | Łódź, Poland  The main idea behind the CARPATCLIM (Climate of the Carpathian Region) Project is to conduct a detailed analysis of the temporal and spatial structure of the climate of the Carpathian region, using unified methods.  The main goal of the project is to construct the gridded climatological database for the region in a daily temporal resolution for the period 1961-2010 by using 0.1° spatial resolution for a number of meteorological variables.  Considering the long period of time and the need to organize and visualize data for various climate variables and indicators it was necessary to design an efficient infrastructure and tools for proficient management of vast amount of climate data. 3 All these requirements can be accomplished by introducing a WebGIS based solution

10. 12th EMS Annual Meeting & 9th European Conference on Applied Climatology (ECAC) | 10 – 14 September 2012 | Łódź, Poland 10 1.Search filter 2.Search results Another important product of the CARPATCLIM project is the Metadata Catalog which is designed as a tool for searching of climate metadata by various parameters (i.e. period, variable, region etc.)The user can search through metadata by using a intuitive filter form. After that the user can further examine detailed metadata for each station in the results list.

11. 12th EMS Annual Meeting & 9th European Conference on Applied Climatology (ECAC) | 10 – 14 September 2012 | Łódź, Poland  Combined, the Digital Climate Atlas and the Metadata Catalog make a powerful online utility which offers a free, fast and easy access to Carpath Climate data.  The Digital Atlas is a WebGIS based solution which relies on the HTML5 technology. As a result the Digital Atlas has rich graphic capabilities and runs on all modern Web browser without the need for any kind of installation  The user interface of the Digital Atlas WebGIS application is designed to be highly intuitive thus making it accesible and usable not only by experts but common users as well. 11
