Background

Seminar for Homogenization and Quality Control in Climatological Databases in 2019 will be the tenth jubilee meeting. From 2014 the Interpolation Conference were organized together with the Seminars considering certain theoretical and practical aspects, as there is a strong connection between these topics since the homogenization and quality control procedures requires spatial statistics and interpolation techniques for spatial comparison of data. The serial of Homogenization Seminars and Interpolation Conferences have been hosted by the Hungarian Meteorological Service. The proceedings of the Conference were published on the WMO/WCP/WCDMP website.

The homogeneous data series with high quality and the spatial interpolation are indispensable for the climatological and meteorological examinations. The primary goal of this meeting is to promote the discussion about the methodological and theoretical aspects.

The main topics of homogenization and quality control are intended to be the following:

• Methods for homogenization and quality control of monthly data series
• Spatial comparison of series, inhomogeneity detection, correction of series
• Methods for homogenization and quality control of daily data series, examination of parallel measurements
• Relation of monthly and daily homogenization, mathematical formulation of homogenization for climate data series generally
• Theoretical evaluation and benchmark for methods, validation statistics
• Applications of different homogenization and quality control methods, experiences with different meteorological variables
• Climate monitoring products

 The main topics of spatial interpolation are the following:

• Temporal scales: from synoptic situations to climatological mean values
• Interpolation formulas and loss functions depending on the spatial probability distribution of climate variables
• Estimation and modelling of statistical parameters (e.g.: spatial trend, covariance or variogram) for interpolation formulas
  using spatiotemporal sample and auxiliary model variables (topography)
• Use of auxiliary co-variables, background information (e.g.: dynamical model results, satellite, radar data) for
  spatial interpolation (data assimilation, reanalysis)
• Applications of different interpolation methods for the meteorological and climatological fields
• Gridded databases, gridded climate monitoring products, digital climate atlases, climate normals

Publication of the papers in a proceedings in the serial WMO/WCP/WCDMP is foreseen after the meeting.
