Bosnia-Herzegovina rains cause floods "worse than war": A strong system of storms delivered a large amount of rain to Bosnia-Herzegovina in mid-May 2014. Floods, landslides, and even the threat of uncovered bombs and shells from the Balkan War made this a markedly dangerous event. Over a million residents of the country were affected.
Research Highlight: Researchers generally use Giovanni to visualize various Earth remote sensing and model data sets, and to perform basic analytical operations on the data available in the system. A novel use of Giovanni was found in the paper by Přemysl Štych, Lucie Malíková, Jan Kříž, and Lukáš Holman, entitled "Multi-temporal analysis of vegetation reflectance using MERIS data in the Czech Republic", published in Miscellanea Geographica. For their study, the researchers used aerosol optical depth (AOD) data from Giovanni to atmospherically correct data from the Medium Resolution Imaging Spectrometer (MERIS), which orbited Earth on Envisat, a European Space Agency satellite. The researchers could see distinct changes in vegetation reflectance dependent on the primary growth periods for different agricultural crops and forest types of the Czech Republic.
Giovanni 4.8 Release: Giovanni 4.8 is a great step forward, with a multitude of new analytical services, and an ever-increasing amount of analyzable data. Be sure to try out the quasi-climatology and seasonal time-series services!
