FIRST ANNOUNCEMENT

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 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.

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.

Highlights and Call for Papers

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

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, digital climate atlases, results of the DanubeClim project
