Weather Station Specifics
UST students from the Physical Geography (Geog112) course visit the weather station atop the John Roach Center, St. Paul campus.
Texas Weather Instruments WRL-32
This weather station is equipped with a wind sensor, indoor and outdoor temperature and humidity sensors with a pagoda, a solar sensor, a lightening sensor, a heated rain collector, and a barometric pressure sensor. The station data logger features 32K of memory and holds approximately 2000 lines of data. The logged data can be recalled on the display, downloaded into a computer, or be queried by an internet connection. Data are currently saved onto a computer (server) in the Geography Department GIS lab and served out via the Tommie Weather web page.
