en-us News from the NASA GES DISC GIOVANNI http://disc.sci.gsfc.nasa.gov/techlab/giovanni/ A short article about the usefulness of Giovanni for environmental research in high school and undergraduate education, is featured at the NASA Web site for educators. http://disc.sci.gsfc.nasa.gov/news/giovanni_NASA_portal.shtml 2008-07-02 GES DISC Chief Scientist Steven Lloyd is demonstrating the use of Giovanni for education at the Earth Science System Educational Alliance (ESSEA) annual conference in Charleston, SC, June 16-19. (http://essea.strategies.org/) /news/detailed_story.html?ii=244 2008-06-17 Giovanni analyses of remotely-sensed chlorophyll concentrations were utilized in this historical study of discharge, nutrients, chlorophyll, and primary productivity in the Mississippi River plume. The study is published in a special issue of Continental Shelf Research. http://disc.gsfc.nasa.gov/news/mississippi_river_plume_study.shtml 2008-06-17 This release focuses on usability issues, as well as the following: new instance for TRMM data, new version 3 OMI products, new MapServer enhancements for gridded products, improved Web Mapping Service (WMS) functionality, enhancements to KML file outputs, and improved error handling. http://disc.gsfc.nasa.gov/techlab/giovanni/Giovanni3.0.6ReleaseNotes.shtml 2008-03-11 The GES DISC will participate in the AGU Fall 2007 Meeting in San Francisco, December 10-14, including 17 papers highlighting recent developments in the Hydrology, AIRS, Giovanni, and Hurricane portals, as well as the A-Train Data Depot, Atmospheric Composition DISC, and other projects. http://disc.sci.gsfc.nasa.gov/conferences/agu_2007.shtml 2007-11-13 New release of NEESPI Giovanni instance is now available. It includes following visualization functions: scatter plot, correlation and difference maps and time series. MODIS atmospheric parameters are updated to Version 5. http://disc1.sci.gsfc.nasa.gov/daac-bin/G3/gui.cgi?instance_id=neespi 2007-08-02 The GES DISC is pleased to announce Version 2 of the A-Train Data Depot, now expanded to further process, archive, allow access to, visualize, analyze and correlate distributed atmospheric measurements from A-Train instruments. http://disc.sci.gsfc.nasa.gov/news/062507_atraingiov.shtml 2007-06-25 A new instance of Giovanni featuring advanced Giovanni 3 (G3) technologies for MODIS daily aerosols is now available. This Giovanni has daily MODIS aerosol products from both Aqua and Terra and for collections 004 and 005 allowing for interesting inter-comparisons and analyese. New analyses functions will be added in the near future. http://disc1.sci.gsfc.nasa.gov/daac-bin/G3/gui.cgi?instance_id=MODIS_DAILY_L3 2007-06-01 The OMI Total and Tropspheric Column NO2 parameters from the level 2G OMNO2G data product are now available through Giovanni. http://acdisc.sci.gsfc.nasa.gov/Giovanni/omi/ 2007-05-24 A new Giovanni instance supporting A-Train with CloudSat and MODIS Aqua data along the CloudSat track is now operational using Giovanni v3. http://disc.sci.gsfc.nasa.gov/news/040507_atraingiov.shtml 2007-04-05 This is the first truly multi-sensor multi-disciplinary Giovanni instance. This NEESPI Giovanni instance is dedicated to the studies of the environment of the Northern Eurasia. This very convenient online exploration tool allows "sensing" the environment at a course resolution, until the next release, and to quickly assess changes in parameters over a selected temporal and spatial region. The tool assists users in finding interesting phenomena, come up with ideas, ask questions about what is displayed, access the actual data for a more elaborated research, and much more.##:####:##This first release of NEESPI Giovanni contains only 1 x 1 deg gridded monthly data: 7 atmospheric parameters from two MODIS instruments onboard Terra and Aqua, 3 MODIS-derived fire products processed by the UMd group and snow/ice products from NOAA.##:####:##In the following releases more data will be added with more parameters and better resolution. The NEESPI Giovanni is now available. /news/detailed_story.html?ii=140 2007-03-30 Three new ocean color radiometry products have been added to Ocean Color Giovanni: merged chlorophyll (from SeaWiFS and MODIS), colored dissolved and detrital matter absorption coefficient at 443 nanometers, and particulate backscatter coefficient at 443 nanometers. These monthly products are from the University of California -- Santa Barbara (Garver-Siegel-Maritorena), part of the Ocean Color Time Series Project REASoN CAN. http://reason.gsfc.nasa.gov/Giovanni/ 2007-03-28 The January 9 issue of the American Geophysical Union's (http://www.agu.org/) weekly newspaper, Eos, has a feature article on Giovanni. The article is entitled "Online Analysis Enhances Use of NASA Earth Science Data". /news/011207-gionews.shtml 2007-01-12 A comprehensive list of all current Giovanni parameters is now available. The list is organized around science keywords from the Global Change Master Directory (GCMD) to facilitate easy navigation. Each parameter is listed with a link to the relevant Giovanni instance. http://disc.gsfc.nasa.gov/techlab/giovanni/GiovanniParameters.shtml 2006-12-19 MODIS Terra and Aqua Collection 5 atmospheres parameters have been added to MOVAS Giovanni with the ability to intercompare Collection 4 with Collection 5. New TRMM V6 3A25 Monthly Rainfall data have been added to TOVAS Giovanni. And NASA Ocean Biogeochemical Model (NOBM) monthly simulated ocean color data have been added to the Ocean Color Time-Series Project Giovanni. http://disc.gsfc.nasa.gov/techlab/giovanni/index.shtml 2006-10-25 Six parameters have been added for Aqua and Terra MODIS daily aerosol product in MOVAS Giovanni. These parameters are: Cloud Effective Radius Combined Phase (Daytime), Cloud Effective Radius Ice Phase (Daytime), Cloud Effective Radius Water Phase (Daytime), Cloud Optical Thickness Combined Phase (Daytime), Cloud Optical Thickness Ice Phase (Daytime), and Cloud Optical Thickenss Water Phase (Daytime). In addition, we now have 15 months worth of daily data available. http://g0dup05u.ecs.nasa.gov/Giovanni/ 2006-05-24 We have added four months of MODIS daily products to MODIS Online Visualization and Analysis System (MOVAS) Giovanni to allow users to start experimenting with daily data. It is still Collection 4, but we are preparing for Collection 5. There is, as yet, no intercomparison option for daily products. For possible uses of daily data, refer to slides 42-63 of this PowerPoint presentation (7.3 MB). It demonstrates the use of daily products from MODIS Aqua, MODIS Terra, TRMM, and OMI to study Saharan dust transport. http://g0dup05u.ecs.nasa.gov/Giovanni/ 2006-05-09 The OMI level 2 Cloud Product (OMCLDRR) using the Rotational Raman scattering algorithm is now available to the public.
