2INTRODUCTION
The West Texas Mesonet project was initiated in
1999 to provide free real-time weather and
agricultural information for residents of the
South Plains region of western Texas. The
network has grown to include fifty-five surface
meteorological stations, one radar wind profiler,
one acoustic wind profiler, and one upper-air
sounding system. Our newest station was just
completed near St. Lawrence, Texas. Weather
information from each surface station is
transmitted every five minutes back to our base
station at Reese Center (12 miles west of
Lubbock). Agricultural data (including soil
temperature and moisture information) are
transmitted every fifteen minutes. All real-time
data collected from the surface stations are
available on our main web page at
www.mesonet.ttu.edu. 55 mesonet stations..in
37 counties..in two states..in two time
zonesand looking to expand!

8Instrumentation
- The following data are collected at each mesonet
station every 5 minutes - 10-meter wind speed and direction (average and
3-second peak wind speed) - 9-meter temperature (for heat flux study)
- 2-meter wind speed
- 2-meter temperature (for heat flux study)
- 1.5-meter temperature and relative humidity
(including dewpoint calculation) - barometric pressure (using digital barometer
calculations include station pressure and
altimeter) - rainfall (total for the 5-minute period and an
hourly summation product) - 2-meter solar radiation (Kipp and Zonen SP-Lite,
CM-3, and CM-21 Apogee PYR-P)
9Instrumentation
- The following data are collected at most mesonet
stations every 15 minutes - Soil Temperature at 5cm (2 inches) under
sod-covered ground - Soil Temperature at 10cm (4 inches) under
sod-covered ground - Soil Temperature at 20cm (8 inches) under
sod-covered ground - Soil Temperature at 5cm (2 inches) for bare
ground - Soil Temperature at 20cm (8 inches) for bare
ground - Soil Moisture at 5cm (2 inches) (all of
these are sod-covered ground) - Soil Moisture at 20cm (8 inches)
- Soil Moisture at 60cm (24 inches)
- Soil Moisture at 75cm (30 inches)
- Leaf Wetness

11Communications
- Radio We use an extended line of sight (ELOS)
radio system to transmit data packets from our
remote stations to our base station at Reese
Center. - Cell Phone Used in remote areas which are
generally east of Lubbock. - Landline Phone Partnership stations with NWS
Lubbock. - DSL/Cable modem Used at a few stations where
local city provides internet. - Wireless Internet Wireless internet at
stationall equipment contained at station. - Internet Spread spectrum radio transmissions
from mesonet station to wherever internet is
available (e.g., courthouse, school, private
residence). Our server is located at that
location for internet access.
12Power Requirements
- All stations use solar panels to charge external
batteries. There is no electricity at any
station. - Each radio station has one 100-watt radio for
communications. The power required to run each
radio varies significantly with each site. - Most sites use two 20-watt solar panels to charge
two deep-cycle gel type marine batteries. The
majority of newer stations use one 50-watt panel. - Several of our major radio repeater stations use
two 50-watt solar panels to charge three
batteries. - Each datalogger has a backup set of internal
batteries to save data in case of a major failure
in the marine batteries.

- Real-time Data Access Real-time mesonet
information (data and products) is free to anyone
on the web page at www.mesonet.ttu.edu . - Average web hits per day 41,000
- For the month of June 2008 2.1 million
hits71,000 hits/day38.8 GB bandwidth9400
unique visitors. - Peak one-day total 156,946 (as of 9/12/2008)
- Maintenance Each station is visited every two
months to complete routine maintenance. When an
instrument fails, we replace it as soon as
possible. If a station is not sending quality
data, it is not helping anyone. - Funding The funding to maintain the West Texas
Mesonet has almost exclusively been provided by
Texas Tech University, although we are pursuing
other opportunities to support maintenance and
continued expansion of the network.

23NWS Lubbock Partnership
- The West Texas Mesonet and the NWS Lubbock office
share a unique relationship. The West Texas
Mesonet provides high quality meteorological and
agricultural information to a region with
otherwise sparse data sources. The NWS Lubbock
relays WTM data to the media and surrounding
community through warnings, forecasts, local
storm statements, and other reports. - The NWS Lubbock, in conjunction with Southern
Region Headquarters, helps with the communication
costs at many stations in the WTM domain.
Currently, there are seven stations on phone
lines that would not be sending real-time data
without this help. - We look forward to a continuing partnership with
the National Weather Service as we expand the
West Texas Mesonet into other regions and
additional NWS County Warning Areas.
