Estimating daily climatologies for climate indices derived from climate model data and observations

Climate indices help to describe the past, present, and the future climate. They are usually closer related to possible impacts and are therefore more illustrative to users than simple climate means. Indices are often based on daily data series and thresholds. It is shown that the percentile-based thresholds are sensitive to the method of computation, and so are the climatological daily mean an...

Hemispheric ozone variability indices derived from satellite observations and comparison to a coupled chemistry-climate model

Total column ozone is used to trace the dynamics of the lower and middle stratosphere which is governed by planetary waves. In order to analyse the planetary wave activity a Harmonic Analysis is applied to global multi-year total ozone observations from the Total Ozone Monitoring Spectrometer (TOMS). As diagnostic variables we introduce the hemispheric ozone variability indices one and two. The...

Oceantea: Exploring Ocean-derived Climate Data Oceantea: Exploring Ocean-derived Climate Data Using Microservices

Ocean observation systems gather an increasing amount of climate-relevant time series data. To interactively explore and analyze such high-dimensional datasets, we developed the software OceanTEA. Our open-source tool leverages modern web technology to support interactive data visualization, spatial analysis of current patterns, and temporal pattern discovery via machine learning methods. The m...

Global changes in seasonal means and extremes of precipitation from daily climate model data

[1] We investigate simulated changes of seasonal precipitation maxima and means in a future, warmer climate. We use data from the ESSENCE project, in which a 17-member ensemble of climate change simulations in response to the SRES A1b scenario has been carried out using the ECHAM5/MPI-OM climate model. The large size of the data set gives the opportunity to detect the changes of climate extreme...
