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 five main themes).
2) There is a chronological list of articles.
3) Short informal texts of a more general nature or with preliminary ideas are in the section: Essays on science.
- 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.

- Downscaling 3D clouds for radiative transfer
- November 2009. The article
(pdf |
doc) describing a new algorithm for the downscaling of 3-dimensional cloud fields has been accepted by the Quarterly Journal. The algorithm is applied to clouds from large eddy simulations and scales the clouds down to scales needed for radiative transfer calculations.
- Article adaptive parameterisations
- June 2009. There is now also an article on two adaptive radiative transfer parameterisations for the Unified Model of the UK Met Office by Manners et al.
- Testing homogenisation algorithms
- June 2009. The final version of the benchmark dataset for testing homogenisation algorithms is finished and available for download. This dataset contains cross-correlated multivariate surrogate data with known artificial inhomogeneities.

- Cloud research e-mail list
- An e-mail distribution list on cloud research and climate.
- Surrogate clouds and Transregio 32
- I am currently working on a DFG-project on surrogate clouds and in the Transregio 32 on structure and exchange processes between the ground, vegetation and atmosphere.
- 4D-clouds project
- My last project on cloud structure and radiation.
