One of the major carriers of diseases are mosquitos and the diseases they have carried have resulted in epidemics with widespread impact. They are vectors for Malaria, Zika, West Nile and Dengue. An estimated 700 million people worldwide are affected by these diseases. In 2015 there was a Dengue fever outbreak in Brazil. During this outbreak, about 1.5 million cases and 1032 dengue deaths were reported. Since Dengue is carried by the Aedes Aegypti mosquito, I have focused my research on the environmental conditions that existed during 2014-2015 in southeast Brazil, specifically in Rio de Janeiro and San Paulo. The data focused on soil moisture, precipitation rates, soil temperature, and land water storage. The measurements were obtained from the data collected by remote sensing Earth orbiting systems. The Giovanni tool developed by NASA Goddard Earth Sciences (GES) Data and Information Services Center (DISC) and the GLOBE Mosquito Habitat Mapper Data were used to georeference observations of mosquito habitats and larvae reported by GLOBE students and citizen scientists, and to collect and organize the raw land cover data and draw correlations and conclusions from it.
