My research work can be accessed in three ways. 1) A list with various scientific themes, with pdf-articles and often color examples and program codes (below are the main themes). 2) There is a chronological list of articles. 3) On my blog variable variability you can find more general or preliminary ideas.

Adaptive parameterisations

Adaptive parameterisation schemes enable more physical parameterisations by splitting the computation in a more physical calculation and an adaptive (statistical) generalisation.

Surrogate clouds

Surrogate cloud fields have certain (statistical) properties of real cloud fields. These can be measured properties or theoretical ones.

Homogenisation of climate records

A benchmark dataset to test homogenisation algorithms.

Radar scattering due to cloud structures

Bragg scatter due to cloud water structures in stead of humidity structures.

Distribution list on homogenization

January 2012. As another prodige of the Cost Action HOME, we have started a email distribution list on homogenisation.

Benchmarking homogenization algorithms

January 2012. The article on benchmarking of homogenization algorithms for monthly temperature and precipitation data has been published by Climate of the Past. See also my blog post.

Adaptive surface module

November 2011. A project using the adaptive parameterisation approach for the soil module of a climate model will start in december. The project is part of the MiKlip program on seamless decadal climate prediction.

Adaptive radiative transfer scheme

July 2011. A Manuscript on a adaptive radiative transfer scheme and its application in the COSMO NWP model has been accepted by the Quarterly Journal.

Predictors for downscaling

May 2011. Our article on natural 3D predictor domains for precipiation downscaling by Tobias Sauter and me has been accepted for publication in the Journal of Climate.

Homogenisation and daily data

November 2010. Our DFG project on better inhomogeneity detection methods for climate records based on daily data has started.

 

Homogenisation e-mail list

An e-mail distribution list on homogenisation of climate data.

Cloud research e-mail list

Adaptive parameterisations and Transregio 32

I am currently working on a DWD-project on adaptive parameterisations and in the Transregio 32 on structure and exchange processes between the ground, vegetation and atmosphere.

Surrogate clouds

My last DFG project on generating structured clouds to study 3D radiative transfer.
