VIEWS News
09.22.2009 - VIEWS 2.0 is launched in a first-stage release.
A new version of the VIEWS website makes its debut. This first-stage release includes a number of hardware, software, organizational, functional, and content-related updates that will serve as a new foundation for the continued evolution of the site. In the months to come, this first release will be followed by additional updates that will introduce new tools and features that build upon the new framework. The redesigned system emphasizes interoperability and Service Oriented Architecture (SOA) that will better facilitate data and metadata exchange between VIEWS and other systems. More info...
07.12.2009 - New production database and web servers
The VIEWS web and database servers were replaced with new machines. The previous machines were several years old, and in spite of continued good performance the VIEWS team decided it was time to upgrade these critical systems. The new machines both have dual quad-core processors, 8 Gigabytes of RAM, and new Intel chipsets. The database server has approximately 4.5 Terabytes of storage space in a RAID array, and the web server has about 1.5 Terabytes on Western Digital Velociraptor hard drives.
05.02.2009 - VIEWS team to collaborate with the Naval Research Laboratory to add NAAPS results to VIEWS
In late 2007, the VIEWS team colloborated with the Naval Research Laboratory (NRL) to submit a winning proposal in response to the 2008 NASA Research Opportunities in Space and Earth Science (ROSES) solicitation. The submission was titled "NASA and NAAPS Products for Air Quality Decision-making", and proposes to add aerosol analyses and forecasts of international aerosol plumes from the Navy Aerosol Analysis and Prediction System (NAAPS) to VIEWS. Work on the project is expected to begin in the latter part of 2009.
03.15.2009 - 2008 VIEWS web traffic statistics have been summarized
At present, VIEWS has over 1500 registered users from over 100 different countries and 500 different organizations, including scientists, students, researchers, planners, and stakeholders. In 2008, the VIEWS website averaged around 1200 unique visitors per day and had a yearly total of 2,343,012 individual page views from around 85,000 unique IP addresses, a volume of traffic that has been steadily increasing every year since the first launch of the system in late 2002. While the majority of visits come from users in the United States, an increasing number are coming from other countries, and we've received several inquiries about the possibility of adding international air quality data to VIEWS.
