The Department of Atmospheric and Environmental Sciences computing facilities are made up of a diverse blend of Sun, Linux, Windows, and Mac computers along with associated printers, networking, storage, and display facilities. User home directories, research disks, scientific software, and real-time and archived geoscience data are hosted on disks served by a NetApp Network Attached Storage (NAS) system. The NAS provides for seamless access from any networked computer, typically via UNIX Network File System (NFS) or Windows Common Internet File System (CIFS). This NAS provides 21 days of backup access. The NAS sits in the University’s Data Center, which opened in 2015. The NAS is also backed up regularly to a facility located at Hudson Valley Community College in Troy, NY. Most PI’s own one or two Dell Precision workstations that are also housed at the Data Center. These workstations have anywhere from 16 to 40 cores with 16 to 128 GB of RAM. Internal disks on these workstations are intended for system and scratch space. Additionally, all user home directories are backed up nightly to a 14 TB capacity Sun tape library in the building which houses department offices. There are still several legacy computing servers that run on Oracle (formerly Sun) hardware and use the Solaris operating system. A Sun Enterprise 280 serves as the department’s web server machine. PI’s and their graduate systems typically have a desktop and/or laptop computer that can perform lower-end computing tasks as well as allow access to computing servers and NAS housed in the Data Center.
The department also partners with UAlbany’s Research IT (RIT) group. This partnership provides access to a DAES-funded Linux computing cluster with 32 Infiniband-connected nodes and 1024 cores. Each cluster node has 256 GB RAM and access to over 75 TB of connected storage; this cluster is also housed in the Data Center. Each PI also has access to 5TB of RIT-provided storage. Most PI’s have a printer (color or mono) in their office, and graduate students can access several public printers.
Real-time meteorological data (point, satellite and radar, and gridded NWP) are pulled from upstream (NCEP and other sources) servers via Unidata’s Local Data Manager (LDM) software. Data is served via the traditional NFS and CIFS means, and also via OpenDAP servers which run THREDDS and/or RAMADDA. Increasingly, faculty and students are using OpenDAP clients such as NCL, GrADS, IDV, and Python to access data stored either on DAES or remote OpenDAP servers.
The NAS is connected directly to the University 10Gb/s fibre backbone. Other servers in the data center are connected to the backbone at 1 Gb/s via switched hubs. There is a 10Gb/s fibre connecting the DAES building to the data center. In the DAES, desktop workstations are connected at either 1Gb/s or 100 Mb/s as needed. UAlbany is connected to the Internet with OC-3 commercial service, along with Internet2.
The department also has access to the supercomputing facilities of the National Center for Atmospheric Research (NCAR) in Boulder, Colorado for use in research projects of truly intense computational nature. The Department of Earth and Atmospheric Sciences computational facilities are maintained and supported by two full time systems administrators who both have backgrounds, and graduate degrees, in Atmospheric Sciences.
The department's state of the art Map Room provides convenient access to the data, and facilitates both formal and informal discussions. The department also has a computational server that is capable of running atmospheric simulations, programs and software for support of research and instruction. These facilites are available to both graduate and undergraduate students who are participating in either course work, research or forecasting.
In addition to excellent on-campus research laboratories and computer facilities, we operate several field stations. An atmospheric observatory (Mohawk Tower) is available on campus for use in research projects undertaken by ASRC scientists, DAES faculty and students. This observatory, which recently has been extensively refurbished, commands a 360 deg view of the surrounding area from the 23rd floor of Indian Quad dormitory.
Laboratory facilities include the Fluid Inclusion Laboratory, located in ES-350. It was established in 2001 with equipment acquired on long-term loan from the Department of Geology at the University of Vermont. The lab contains a Fluid Inc. heating/freezing stage, a Nikon Optiphot binocular transmitted light microscope, a Doric Trendicator 410A digital temperature readout, a Javelin JE3362 TV camera, and a Sony PVM-1390 color video monitor.
The Geochemistry Laboratory, located in ES-342, is used for both research and teaching. It was renovated in 1999 by faculty and students, with funds from an NSF CCLI grant which included matching funds from the Department and the University. It contains two fume hoods, glassware, drying ovens, balances, and other standard equipment.
The rock sample preparation laboratory, located in the ES-B09, contains various pieces of equipment for crushing, grinding, and pulverizing rock, soil, and sediment samples. The rock saw and thin section preparation laboratories (ES-B08) contain several rock saws of various sizes, as well as polishing equipment.
We have an extensive collection of rock and mineral samples, thin sections, and crystallographic models located in ES-237. This collection is used primarily for teaching.
