Incorrect SPSNOW data occur during the following periods:##:##19790101-19840101##:##19890101-19931201##:##19980101-20011001##:####:##SPSNOW is the spurious snow source used to maintain stability and balance in the mass budget. In general, it should be a very small term and is included in the output to provide more accurate water budgets.##:####:##This error exists in in the MERRA archive data, but there are plans to correct the files. /news/detailed_story.html?ii=370 2009-10-05 While it has been a relatively quiet hurricane season in the Atlantic basin, typhoons have been very active in the western Pacific, perhaps augmented by El Niño. Typhoons Morakot, Ketsana, and Parma have caused considerable damage, and typhoon Melor is huge and dangerous. http://disc.sci.gsfc.nasa.gov/gesNews/super_typhoons 2009-10-05 GSFC's Hydrological Sciences Branch and Goddard Earth Sciences Data and Information Service Center (GES DISC) are pleased to announce the release of North America Land Data Assimilation System Phase 2 (NLDAS-2) data products in the Hydrology DISC. http://disc.sci.gsfc.nasa.gov/gesNews/nldas-data-available-from-the-hdisc 2009-09-28 An article on the NASA DAACs Web site describes how data from MODIS, MISR, and OMI were used to study air pollution and smoke in the city of Athens during an outbreak of fires in Greece in 2007. OMI data were used to distinguish aerosol types. http://disc.sci.gsfc.nasa.gov/gesNews/smoke_over_Athens 2009-09-18 A new service converting Level-3 TRMM_3B43 data in HDF4 format into netCDF format is now available through Mirador. netCDF is a data format commonly used by the meteorologic and climate science communities. http://disc.sci.gsfc.nasa.gov/gesNews/trmm_3B43_netCDF_conversion 2009-09-17 The version 3 OMI Level 2 Ozone Profile Product OMO3PR is now available to the public.

These date are available for the period 01/01/2000 to 12/31/2007. http://disc.sci.gsfc.nasa.gov/gesNews/gocart_data_V006 2009-08-28 This week, scientists from NASA GSFC, including GES DISC scientist and data manager Gregory Leptoukh, are participating in a seminar on satellite observations of atmospheric aerosol properties. http://disc.sci.gsfc.nasa.gov/gesNews/germany_aerosol_workshop 2009-08-19 It may be hot and humid right now, but an analysis of Atmospheric Infrared Sounder (AIRS) temperature data confirms that June and July were unusually cool for much of the Eastern Seaboard of the United States. http://disc.sci.gsfc.nasa.gov/gesNews/cool_June_July_US_northeast 2009-08-14 Mirador, the GES DISC Earth Science Search Tool, now offers another view of GES DISC data sets, using the new Science Areas tag. The new "drill-down" interface allows users to find data sets organized according to physical properties measured in the data. http://disc.sci.gsfc.nasa.gov/gesNews/mirador_discipline_search 2009-08-12 Typhoon Morakot began development as a tropical depression on August 03 at 18Z located southwest of Taiwan at approximately 21.2 N, 135.9 E. The storm hit Taiwan on August 7th and seemed to slightly stall over a two-day period, dumping over 80 inches of rain. On August 08, the highest amount of rainfall ever for Taiwan was recorded at 55 inches. These torrential rains have caused massive flooding and mudslides, one occurring overnight which could have a possible death toll of more than 600. A newly development storm, Etau, occurred over the weekend (August 08-09) but seems to have trouble gaining strength heading towards Japan. ##:####:##Typhoon Morakot animation and Taiwan image were created using the TRMM 3B42RT data of the Accumulated Rainfall parameter using the GES DISC TRMM Online Visualization and Analysis System (TOVAS)(http://disc2.nascom.nasa.gov/Giovanni/tovas/), which contains TRMM rainfall products, near-real-time 3-hourly, Multi-Satellite Precipitation Analysis, and rainfall ground observation data. An infrared images was created using the Merged IR data, which is a globally-merged (60N-60S) pixel-resolution IR brightness temperature data set(equivalent blackbody temps), merged from all available geostationary satellites (GOES-8/10, METEOSAT-7/5 & GMS). The data is available by ftp from the GES DISC (http://disc.sci.gsfc.nasa.gov/data/datapool/TRMM/01_Data_Products/06_Ancillary/01_Global_MERG_IR/index.html). The RGB image is from MODIS Terra on August 07 as the typhoon was over Taiwan. /news/detailed_story.html?ii=357 2009-08-10 Release Notes are currently available for Release 3.0.8.1 of Giovanni. Implementation and testing of the operational system is continuing. Giovanni users may experience anomalous behavior or errors, which can be reported; see 'Read More'. http://disc.sci.gsfc.nasa.gov/gesNews/giovanni_3.0.8.1_release_notes 2009-07-31
