Finally, after years of waiting, and again thanks to Dr. Ramón (and the infrastructure that provides iEcoLab ), I have material to hang up "heavy" permanently. So, taking advantage of this situation, I have uploaded for free download the variables I used to calibrate predictive models of distribution of the final chapters of my thesis .
To be more precise, what I posted are 309 raster maps in ARCINFO ESRI ASCII format and coordinate system 23030 EPSG (ED50 UTM zone 30) covering the mainland of Andalusia at a resolution 40 meter horizontal. The maps have a 7500 x 13000 cells, leaving them at around 54.7 million cells (rounded). Are compressed. Zip, with sizes discharge ranging between 128 and 1.5 MB.
To access the downloads you can go to the page thesis in paragraph Predictors. Within the directory there are two folders:
- climate: climatic maps containing the average annual precipitation and mean maximum and minimum temperatures in summer and winter for the period 2000-2100 in 10 years for combination of the IPCC scenarios A2 and B2 with global circulation models and CGCM2 ECHAM4. These maps have been derived from information made publicly available by the AEMET . More information in the README file .
- other : contains a miscellany of variables ranging from distance to entities of interest, frequency of these entities, Landsat bands, NDVI, and a good set of topographic variables. More information and a complete list of maps, on the other README file.
These variables are ideal for calibrating models of distribution and project into the future with the aim of evaluating the potential impact of climate change on species distribution, or simply to meet the environmental conditions different populations (no matter whether lettuce or bugs) along the territory.
If you're going to use them, I'd appreciate that you had in mind two things:
- Please, if you're going to publish a work in which you use this data, citalopram as Benito, BM (2009) Applied to the Conservation Ecoinformatics : Simulation of Effects of Global Change on the Distribution of the Flora of Andalusia. Doctoral Thesis, Department of Botany, University of Granada (URL: http://ide.ugr.es/blasbenito/tesis/) .
- Our server has a limited bandwidth. We are very grateful to not abuse downloading everything at once, and, if possible (which it is!), programming your massive downloads to run at night so as not to hinder daily access to data from other users.
If you have problems or suggestions regarding this dataset, do not hesitate to contact me.
That's all folks!
