An updated tally of journal publications in which the NASA Giovanni data system was utilized yielded 35 new publications since April 2011. Since the first incarnations of Giovanni were available in 2004, the Goddard Earth Sciences Data and Information Services Center (GES DISC) has now counted 371 peer-reviewed publications that have utilized the system. The current publication rate is on pace to equal or exceed the 115 publications that appeared in 2010.
Giovanni provides remotely-sensed data from several NASA Earth observing satellites, notably instruments on the EOS triad of Terra, Aqua, and Aura, and also instruments on satellites in the A-Train orbital constellation. In addition, precipitation data products from the Tropical Rainfall Measuring Mission (TRMM) and related projects are available in Giovanni. The system also features output from data assimilation models, with the Modern Era Retrospective-analysis for Research and Applications (MERRA) and the North American and Global Land Data Assimilation Systems (NLDAS and GLDAS) the most widely used.
A few examples of these recent publications demonstrate the diversity of research topics to which Giovanni has contributed significantly:
- Giovanni was used in two different studies about solar energy. Vicente Lara-Fanego and colleagues in the Solar Radiation and Atmosphere Modeling Group at the University of Jaén in Andalusia, Spain evaluated solar irradiance forecasts for southern Spain in the journal Solar Energy; and Dev Millstein and Surabi Menon of the Lawrence Berkeley National Laboratory examined the effect of "cool roofs" and photovoltaic arrays on regional climate in Environmental Research Letters.
- The effect of population growth in India on aspects of the regional climate was the subject of two publications. Pavel Kishcha, Boris Starobinets, and Pinhas Alpert of Tel Aviv University, along with Olga Kalashnikova of the NASA Jet Propulsion Laboratory, looked at the effect of population growth on atmospheric aerosols over the subcontinent of India (International Journal of Remote Sensing). The temperature of India, particularly the temperature of its megacities, was the subject of Chinmay Mallik and Sayim Lal's paper in the journal Current Science.
- In the Andes of Peru, Marco Otto and colleagues at the Technische Universität Berlin used Giovanni in a study of the hydrology of high altitude wetlands. One of Giovanni's flagship data sets, data from the Atmospheric Infrared Sounder (AIRS) on the Aqua satellite, was used to examine forecasts of cloud parameters in research by Louis Garand, Ovidiu Pancrati, and Sylvain Heilliette of Environment Canada, published in Atmosphere-Ocean.
- The ocean yielded several interesting studies of phytoplankton. In a study updating a Science Focus! article on the GES DISC Web site (linked here), Thomas Ohde and Volker Mohrholz from the Leibniz Institute for Baltic Sea Research characterized the interannual variability of toxic sulphide eruptions from the seafloor off the coast of Namibia. Olaf Krüger and Hartmut Graßl examined the climatically-intriguing relationship between Southern Ocean phytoplankton, cloud albedo, and precipitation in a paper published in Geophysical Research Letters.
Finally, while doctoral dissertations are not included in the list of Giovanni publications (even though Giovanni has been used in numerous theses and dissertations), we had to mention the tantalizingly titled "Sex and symbionts: New discoveries in local and regional patterns of coral reproduction and ecology", written by doctoral candidate in Marine Ecotoxicology Micaela Hellström of the University of Stockholm. The use of Giovanni to examine the intricacies of coral reproduction – and perhaps to yield insight to aid their preservation – is yet another example of the wide world of research that NASA's Giovanni system enables.
