Peckham, S. Also interesting is the works on rinormalization group and turbulences of which this is a google synthesis. Huge and overwhelming indeed, it was the starting point of this my own post.

Sunday, December 29, Snowflakes is Christmas time after all, and I live in a boreal place. Christmas time remembered me to give a look to snow crystal formation literature and models.

To my surprise, a definitive thermodynamic theory of their formation does not exist. This is what can be deduced form the review paper by the K.

For a classification of snow crystal, Magono paper, would be fine. I am looking forward to read them all starting from the Libbrecht review and his two most recent papers, which seem to add something and complete this post more appropriately eventually. For the moment, be happy with the bibliography. Fu et al. In that case, I was looking for literature in the area of fractal surfaces.

Something else should be available. In particular, I was looking for a papers by J. In any case, growth of this type of forms is pretty general and ubiquitous as shown in many papers, and in particular, in Ben Jacob 's ones.

I also indulged in adding some papers about snow crystal methamorphism. This is not the topic of the post, but for the moment I keep trace of them in here.

Other papers were just added for getting some general reference to crystal growth e.Model description paper 03 Dec Annales Geophysicae. Atmospheric Measurement Techniques.

A simple method to record heave and subsidence of the land surface at specific field locations is described.This new model is specified on a 1x1 degree grid and incorporates an updated version of our global sediment thickness.

ETOPO1 is a 1-arc minute model of Earth's global relief, including surface topography and seafloor bathymetry. In ice-covered regions, "ice surface" and "bedrock" are given. In both these models, the crustal types were also used to assign ice, sediment and crustal thickness.

But the crustal types are now aligned with the crustal age map of Artemieva and Mooney. Additional crustal types mark specific tectonic settings, such as orogens, continental rifts, continental shelves and oceanic plateaus. Each of the 1x1-degree cells will have a unique 8-layer crustal profile where the layers are.

Seismic tomography has been extensively used in various forms to determine the three-dimensional velocity structure of the Earth's mantle. The data used in these studies are surface wave waveforms and dispersion measurements and free oscillation frequency shift data as well as body wave travel times arrival times from catalogues such as the ISC catalog and specially hand-picked long-period arrivals.

For the majority of these studies, the crust has a significant impact on the observed seismic data but, at the same time, is too thin to be resolved by them.

Most authors handle this by applying an assumed "crustal correction" to the data before an inversion for mantle structure. Since the inversion techniques can erroneously map crustal structure down to great depth at least kmaccurate crustal corrections to the data sets are extremely important. Another aspect is the seismic monitoring of nuclear explosions. Key elements of the monitoring effort are location and size estimation.

The location accuracy strongly depends on the chosen velocity model i. Monitoring on regional scale includes the modelling of short-period surface waves and the propagation of Lg waves which are very sensitive to variations of crustal structure.

Obviously, an accurate image of the Earth's crust would tremendously improve the understanding of wave propagation of such phases. With the volume of datasets and the demand on resolving small-scale structures increasing, we found that the 2x2 degree model CRUST2.Monday, December 30, Turbulence.

GEOtop Endrizzi et al, and references therein is a distributed model of the mass and energy balance of the hydrological cycle. GEOtop is applicable to simulations in continuum in small or relatively large montain catchments. GEOtop deals with the effects of topography on the interaction between energy balance and hydrological cycle water, glacier and snow with peculiar solutions.

The source code of GEOtop 2. GEOtop executable will be created in the subdirectory "bin".

For a "geotopOptim" within the R environment, see the package documentation. The package contains an R script whick you can get by typing 'system. This scripts calibrates soil parameters for soil moisture modeling with GEOtop hydrological model. THe calibration algorithm is based on Particle Swarm Optimization. To run the script, see the usage and the options which can be omitted and replaced by the related enviroment variables:.

The function "geotopPSO" calibrates 1D simulation profile mastering the soil property profile file, often referred as "soil In this case a decrease of hydraulic conductivity or soil porosity can be modeled. So the reported values refer to a range for so many soil parameter of the same type how many the soil layers are. The keyword "SoilInitPres" refers to the initial soil water pressure head.

The keyword "PsiGamma" refers to the soil water pressure gradient along the terrain-normal downward direction and is applied to calculate initial soil water pressure head in the above layers assuming a continuous profile.

Currently December there are several development branches in this repostory. Most used branches are the followings:. However, this branch is not fully stable when the model is used with full 3D water and energy budget settings.

It is the most stable GEOtop version and the current benchmark for the development versions. The 3. It performs exactly as the se27xx, but it has some improvements in terms of:. However, it still lacks of the integration with the MeteoIO library and other features implemented in the current 2.

In the next months we plan to move toward stable 3.

We as developer would like to have some feedbacks from you! Bugs and suggestions can be addressed in the google groups or using pull requests. Further test cases to validate the model are also welcome. During the years, several scripts and external softwares have been developed for preprocess GEOtop inputs, postprocess and visualize results.
