TRMM rain rate quasi-climatology for the state of New York in August. Variations in rainfall and sunlight in the summer are important for viniculture in the Finger Lakes region of New York.

The February  2014 issue of The Giovanni News is now online. This issue has three feature articles: 

Research Highlight:  Many areas of India are affected by high concentrations of atmospheric aerosols.  In this research paper, the authors, led by B.S. Murthy,  investigated the effect of these aerosols on evapo-transpiration; the rate at which water either evaporates from the Earth's surface or which is released by living plants.  High concentrations of atmospheric aerosols reduced incoming solar radiation, which led to reduction in evapo-transpiration rates and other related processes.

Update on the Data-enhanced Investigations for Climate Change Education (DICCE) Project:  The DICCE Project is currently planning how to adapt to the new capabilities offered by Giovanni-4.  Meanwhile, the current DICCE data interface was used for a classroom project investigating aerosols stemming from biomass burning over Scandinavia.  It was also used in a student classroom project working on the creation of a flash flood forecast system for California.

Giovanni-4 Development Update - Quasi-Climatologies:  In climate science, a climatology refers to a data record that is usually at least 30 years long.  Many satellite data records are not that long yet, so creating an average of several years of data is termed a quasi-climatology. Giovanni-4 now is readying the capability to make quasi-climatologies for many parameters, for both months and seasons.  As a demonstration, a 13-year quasi-climatology of precipitation for the state of New York was created, to investigate whether or not the Finger Lakes is really a good region for growing wine grapes. It appears that it is.
