The Global High Frequency Radar Network

High Frequency (HF) radar is an integral component of many ocean-observing systems. Thirty-four countries currently operate HF radar stations for oceanographic measurements. A global effort has been underway for the past two years to standardize the HF radar data products and develop emerging uses for the information.

Applying Geospatial Semantic Array Programming for a Reproducible Set of Bioclimatic Indices in Europe

Bioclimate-driven regression analysis is a widely used approach for modelling ecological niches and zonation. Although the bioclimatic complexity of the European continent is high, a particular combination of 12 climatic and topographic covariates was recently found able to reliably reproduce the ecological zoning of the Food and Agriculture Organization of the United Nations (FAO) for forest resources assessment at pan-European scale, generating the first fuzzy similarity map of FAO ecozones in Europe.
