What is a Turf Irrigation Water Management Program?

The TIMS Water Management Program is available to North Carolinians to calculate and track irrigation use. Using the NC Climate Office current weather data, TIMS can tell you in number of minutes how long to water your lawn.

Why Should You Use It?

Our hope is that after a few weeks of use, lawn owners will be able to save at least 25% of normal irrigation.

Why You Tell Others to Use it TOO

If 100,000 people use this program to schedule irrigation, North Carolina could save millions of gallons of water and maintain healthier lawns. Just answer a few simple questions about your lawn and start your water diary today!

TURF IRRIGATION MANAGEMENT SYSTEM

CENTERE for Turfgrass Environmental Research & Education

The success of the TIMS project is due to the partnership and hard work of the North Carolina State Climate Office, the Department of Crop Science and the NCSU Turf Workgroup. Funding for this project has been provided by the Center for Turfgrass Environmental Research and Education at NCSU.

NC SCO DATA

The precipitation estimates provided herein are derived from National Weather Service's WSR-88D Doppler Radar. Radar precipitation estimates can be grossly inaccurate, so radar-based precipitation values are calibrated with observations from routinely available hourly surface gauges.

The combined product provides the spatial resolution of radar with the increased accuracy of surface gauge networks. These gauge-calibrated radar estimates are known as Multi-sensor Precipitation Estimates, or MPE. The MPE grids used in this tool are routinely produced by the National Weather Service and National Centers for Environmental Prediction.

MPE is not perfect, and still has known errors. A study by the State Climate Office of North Carolina suggests that MPE compares well with an independent daily precipitation gauge network over the Carolinas, with an average daily error of approximately 0.25 inches.

Error tends to be lower in the winter and higher in the summer. While MPE is the best available operational estimate of rainfall for locations where gauges are not available, it can't consistently replicate the accuracy of onsite rain gauges.

TurfFiles is funded by the Center for Turfgrass Environmental Research & Education (CENTERE) through public and private grants.
