Tutorials

I've written few tutorials and examples for linux basic commands, netcdf files manipulation, nco and the ferret visualization software.
This can be useful for PhD / master students starting basic analysis. The files are in pdf format.

If we come back to the stoneage, can malaria occur over Europe?

Malaria simulations have been achieved using the Liverpool Malaria Model (LMM) over Europe for the period 1990 to 2006. Different sources of climate data have been used to drive LMM: NCEP and ERAINTERIM reanalysis, and the ECA (Eobs) dataset at 25km resolution (only the mediteranean basin).

The malaria incidence is weak during winter (DJF) and spring (MAM), due to unsuitable cold temperatures conditions.
During summer (JJA) and fall (SON), there is a climate risk of malaria occurence over Italy, soutwestern France (the Bordeaux region) and the Balkans (Slovakia, Hungary, Romania, Ukraine). There is also a risk over the western tip of Portugal. Most of these features are relatively consistent accross the different climate datasets used to drive LMM.

Note that these features are relatively consistent with the ones raised in the Reiter's paper
