9th SEMINAR FOR HOMOGENIZATION AND
QUALITY CONTROL IN CLIMATOLOGICAL DATABASES
AND
4th CONFERENCE ON SPATIAL INTERPOLATION TECHNIQUES IN CLIMATOLOGY AND METEOROLOGY
BUDAPEST, HUNGARY
3 – 7 April 2017
Organized by the Hungarian Meteorological Service (OMSZ)
Supported by OMSZ and WMO
Background
The first eight Seminars for Homogenization and Quality Control in Climatological Databases as well as the first three Conferences on Spatial Interpolation Techniques in Climatology and Meteorology were held in Budapest and hosted by the Hungarian Meteorological Service.
The 7th Seminar in 2011 was organized together with the final meeting of the COST Action ES0601: Advances, in Homogenization Methods of Climate Series: an integrated approach (HOME), while the first Conference on Spatial Interpolation was organized in 2004 in the frame of the COST Action 719: The Use of Geographic Information Systems in Climatology and Meteorology. Both series were supported by WMO.
In 2014 the 8th Homogenization Seminar and the 3rd Interpolation Conference were organized together considering certain theoretical and practical aspects. Theoretically there is a strong connection between these topics since the homogenization and quality control procedures need spatial statistics and interpolation techniques for spatial comparison of data.
On the other hand the spatial interpolation procedures (e.g. gridding) require homogeneous, high quality data series to obtain good results, as it was performed in the Climate of Carpathian Region project and in the Climate of Danube Region project as well, which were led by OMSZ and supported by JRC. The main purpose of the CarpatClim project was to produce a gridded database for the Carpathian region based on homogenized data series. The DanubeClim is the spatial extension of the CarpatClim The aim of the project is to extend the data series for the whole catchment area of the Danube. In the DanubeClim the same methods are applied for homogenization, harmonization and interpolation as were in CarpatClim. The first phase of the project has been finished in 2016.
The WMO CCl set up team to support quality control and homogenization activities at NMHSs. The main task of the Task Team on Homogenisation (TT HOM) to provide guidance to Members on methodologies, standards and software required for quality control and homogenization of long term climate time-series. The results of the homogenization sessions can improve the content of the guidance is under preparation.
In the “Climate monitoring products for Europe based on Surface in-situ Observations high-resolution gridded information products is generated in Copernicus Climate Change Service (C3S) Climate Data Store (CDS)” project a consistent set of high-resolution gridded information products is generated building upon ECA&D and E-OBS and covering all of Europe. The service will provide access to additional gridded datasets based on in-situ observations available for a number of multi-national (but sub-European) regions in Alpine region, Fennoscandia and the Carpathian region. Access to all data products, meta-data, user guidance, and documentation will be provided via the Climate Data Store (CDS). Homogenization and interpolation methods are in the focus of this activity. The discussions will provide a good opportunity to appoint the methodological questions are addressed.
