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.

NASA’s CYGNSS Constellation of Hurricane Remote Sensing Satellites

A new NASA satellite mission, CYGNSS (Cyclone Global Navigation Satellite System), combines the all-weather performance of GNSS bistatic ocean surface scatterometry with the sampling properties of a constellation of satellites. This will result in spatial and temporal sampling properties which are markedly different from conventional imagers.

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.

Predicting Future Forest Ranges Using Array-based Geospatial Semantic Modelling

Studying the impacts of climate change requires looking at ranges of variables that transect a broad range of sectors. Geospatial Semantic Array Programming (GeoSemAP) offers the potential to help create a cross-discipline vocabulary for discussing data and processes used in geospatial studies. Within this field, the PESETA II project offers an example of how GeoSemAPs can be used to address the ecological challenges associated with a shifting climate.

Drones Are Taking Pictures That Could Demystify A Malaria Surge

Four hundred feet above a Malaysian forest, a three-foot eBee drone hovers and takes pictures with a 16-megapixel camera every 10 to 20 seconds. But it's not gathering images of the mosquitoes that transmit malaria. Even today's best drones aren't capable of such a photographic marvel. Rather, the drone is looking at a changing landscape that holds clues to the disease's spread.
