About TexMesonet


Together with partners across the state, the Texas Water Development Board (TWDB) has developed TexMesonet — a statewide earth observation data collection network.

TexMesonet establishes a unifying architecture for networks across Texas, aggregating data into central location that includes stations maintained by the National Weather Service (NWS) and several other regional and local entities. And, TWDB continues to strategically add its own managed stations to improve statewide coverage.

TexMesonet utilizes MesoWest and SynopticLabs Mesonet API to access data from these stations as well as independent meteorological stations, including several buoy sites in the Gulf of Mexico. Many citizen-cooperator sites or special-purpose networks measure only one or two parameters. Collectively, these several hundred locations contribute meaningfully to the complete meteorological data presented by and available on TexMesonet.

Data Information

What data is displayed and graphed?

The TexMesonet Map Viewer shows the current conditions for all mesonet stations. Detailed information can be displayed for each station by either hovering over or clicking on the station. Clicking opens a pop-up where you can choose to view:

  • Current – This is the most recent data read at varying intervals (5 or 15 min. for TWDB stations). Date and time of the read is shown at the bottom, and data collected varies by station.
  • Forecast – The current forecast from the NWS for the station site.
  • Graphs – Shows data trends over the previous 1, 2, 3 days, or 1 to 2 weeks. Graphs will only display if data is available.

How is data collected and distributed?

  • Data is collected using Campbell Scientific Data Loggers (CR300 and CR1000). The data is currently logged at 5- or 15-minute intervals
  • LoggerNet retrieves the data from each of the stations every 5 minutes. Shortly afterwards the data is loaded into the database.
  • Our web services drive the near real time data distribution and display on https://www.texmesonet.org. See our Data Services page for more information.

What is the source for our weather radar?

TexMesonet displays the National Weather Service (NWS) Next-Generation Radar (NEXRAD) network of weather via services from Iowa State University of Science and Technology. For more information visit the Iowa Environmental Mesonet (IEM).

What are some uses of the data?

The data is broadly applicable. For example:

  • Support statewide flood monitoring and flood forecasting
  • Monitoring and response to drought and wildfires
  • May help with more efficient irrigation in both rural and urban contexts

New parameters and functional enhancements are added on an ongoing basis with the goal to help all Texans more easily monitor, interpret, and utilize the network’s data.
