This study explores a domain-filling trajectory approach to generate a global ozone climatology from relatively sparse ozonesonde data. Global ozone soundings comprising 51 898 profiles at 116 stations over 44 yr (1965–2008) are used, from which forward and backward trajectories are calculated from meteorological reanalysis data to map ozone measurements to other locations and so fill in the sp...

In this experience report we consider some issues in the development of a data warehouse for meteorological and climatology data at MeteoSwiss. The paper describes the meteorological and climatology data process, the data warehouse architecture developed to support this process while integrating legacy systems and some of the modelling issues encountered.

Solar surface irradiance is an important variable in many different fields, e.g., climate monitoring and solar energy. Remote sensing data are nowadays well established and the only observational data source in many regions of the world. Aerosols significantly affect the clear sky radiation and hence also the all sky radiation. In order to achieve the optimal accuracy for surface radiation, inf...

Highlights of the 6th International GEWEX Science Conference and Joint GEWEX/iLEAPS Sessions Melbourne, Australia, 24–28 August 2009 See page 11 Global Precipitation Climatology Project (GPCP) Version 2.1 precipitation climatology, 1979–2008, in mm/day. This combination of satellite estimates based on infrared, microwave, and sounding data, together with gauge analyses, yields a global average ...

The inter-comparison of different soil moisture (SM) products over the Tibetan Plateau (TP) reveals the inconsistency among different SM products, when compared to in situ measurement. It highlights the need to constrain the model simulated SM with the in situ measured data climatology. In this study, the in situ soil moisture networks, combined with the classification of climate zones over the...

This paper discusses the state of European research in historical climatology. This field of science and an overview of its development are described in detail. Special attention is given to the documentary evidence used for data sources, including its drawbacks and advantages. Further, methods and significant results of historical-climatological research, mainly achieved since 1990, are presen...

Representation error arises from the inability of the forecast model to accurately simulate the climatology of the truth. We present a rigorous framework for understanding this kind of error of representation. This framework shows that the lack of an inverse in the relationship between the true climatology (true attractor) and the forecast climatology (forecast attractor) leads to the error of ...
