The count of peer-reviewed research publications that have utilized the GES DISC Giovanni system to analyze and visualize remote sensing data from NASA satellite missions has increased year after year. It was apparent this summer that the number of publications in which Giovanni was used was likely to exceed the noteworthy number of 100 —
and after our last survey of research publications, it did. The count now stands at 107. In total, there have been 286 publications (that we've found) which have used this remarkable system since it first became available.
Numbers like 100 publications in a year are very noteworthy, and noticeable. What this numerical achievement should do, however, is draw further attention to the breadth and depth of Giovanni use across multiple disciplines in earth system science. 100+ journal publications in a year is only a leading indicator; our survey of research contributions also finds many more conference proceedings, reports, dissertations and theses that utilize Giovanni.
This milestone is remarkable primarily because of what Giovanni does. Giovanni does not just deliver data; indeed, data from NASA Earth remote sensing missions appears in many, many more than 100 publications annually. But in most of those cases, researchers find the data, download the data, and then devise ways to analyze and display the data themselves to support their research endeavors. In the case of Giovanni, researchers don't have to do that; they can use Giovanni's suite of analytical capabilities and multiple visualization options, saving large amounts of time and considerable effort. Giovanni visualizations are used in research publications with very few changes (in fact, sometimes no changes at all are needed). The strongest achievement of Giovanni is that its output is accepted as scientifically valid, scientifically useful, and scientifically meaningful. There are very few other systems in the world that take data from an archive system, analyze it, display it (all using the World Wide Web) and then transfer almost immediately onto the pages of esteemed scientific journals. Giovanni has achieved this level of scientific integrity in many sub-disciplines of Earth science.
The remarkable reach of Giovanni can be ascertained by an examination of some the most recent "batch" of publications that have been listed in our 2010 compilation:
- Pinker et al. used Photosynthetically Active Radiation (PAR) to examine estimates of terrestrial net primary productivity. (International Journal of Remote Sensing)
- Dupouy et al. used Giovanni in an examination of ocean optical properties and chlorophyll concentrations around the reefs of New Caledonia. (Marine Pollution Bulletin)
- Saaed and Al-Dashti examined the dust storm that affected military operations during Operation Iraqi Freedom. (Theoretical and Applied Climatology)
- Mutekanga et al. employed the system to assess erosion risk and inform decision-makers for a watershed in Uganda. (Geoderma)
- Bulmer and Farquhar used the system to guide development of a geohazard monitoring system near Machu Picchu, Peru – the importance of which was illustrated when thousands of tourists were stranded in the region by heavy rains in January of this year. (Natural Hazards and Earth System Science)
- Kumar et al. observed ozone concentrations at Nainital, high in the central Himalayan mountains. (Journal of Geophysical Research)
- Lannuzel et al. used Giovanni in an assessment of dissolved iron concentrations (important for phytoplankton physiology) in Antarctic ice. (Journal of Geophysical Research)
Furthermore, Giovanni is now being written about in publications describing how to better deliver remote sensing data to users in the public sector, for applications such as fishery management and land-use monitoring.
So, while we celebrate reaching the century mark -- much as a skilled cricket batsman would do, we take a quick bow and immediately get right back into the swing of things: providing the best remote sensing data analysis and visualization system that our dedicated staff can devise. Seeing more than 100 Giovanni publications in 2010 challenges us to do better and to make Giovanni even more effective and useful for geoscience research and education.
