SESDA 3 team contributes to release of April 2014 issue of The Giovanni News
May 22, 2014
The April edition of The Giovanni News includes several articles by SESDA 3 team members working at the Goddard Earth Sciences Data and Information Services Center (GES DISC):
Research Highlight: Summer-time lightning activity and its relation with precipitation: Diurnal variation over maritime, coastal and continental areas: The frequency of summertime lightning strikes was examined in terms of three factors: rainfall intensity, strike location (open ocean, coastal, or land), and time of day. The coastal and land locations exhibited larger variations in lightning strike frequency during heavy rainfall and the time of day of highest strike rate compared to the open ocean. Giovanni was used to obtain hourly precipitation rate estimates for this study.
The Hovmöller Diagram – Seeing Geographic Patterns in Earth Remote Sensing Data over Time: The Hovmöller diagram is an excellent way to visualize the change in an environmental variable over time either latitudinally or longitudinally, such as plotting the variability of sea surface temperature (SST) in the Pacific Ocean during El Niño and La Niña events. Giovanni has provided the ability to create Hovmöller diagrams since the system went into operation. This ability has been enhanced thanks to new software developed in-house by the GES DISC team at Goddard Space Flight Center.
Giovanni-4 Development Update – Image Download Capability: Giovanni-4 has added the capability to download images in TIFF format. Prior to this, Giovanni visualization output was available only in the form of PDF files. In the case of Giovanni-4 images, what you see on the screen is not always what you get in the full downloaded image, which can have considerably more information. The TIFF image files provide greater flexibility for using Giovanni output, and easily can be converted to JPG or PNG format.
