Meteorological Data for Erath andNorthern Hamilton Counties, Texas

The Texas Institute for Applied Environmental Research (TIAER) at Tarleton State University, Stephenville, Texas, has been conducting studies of environmental impacts on surface water quality, as a result of storm water runoff from dairy operations, since summer 1990. The studies have focused on the Upper North Bosque River (UNBR) watershed in Erath and northern Hamilton Counties, Texas (Figure 1), in which there are presently 60 - 65 dairies with a total of nearly 30,000 milking cows.

Figure 1 Upper North Bosque River watershed.

Additional studies initiated by TIAER since 1996 necessitated expansion of rainfall collection sites outside the upper North Bosque watershed. Figure 2 depicts the location of TIAER rainfall monitoring sites in the upper North Bosque watershed, and Figure 3 depicts all TIAER rainfall monitoring sites in the Lake Waco watershed.

The studies in the UNBR watershed have included: U.S. Environmental Protection Agency (EPA) Clean Water Act Section 319 projects directed by the Texas State Soil and Water Conservation Board (TSSWCB), a congressional initiative funded through the EPA, a U.S. Department of Agriculture NRCS PL-566 project directed through the TSSWCB, a grant from the Texas Air Control Board (now merged with the Texas Natural Resource Conservation Commission), and presently, the Lake Waco-Bosque River Initiative funded by the U.S. Department of Agriculture.

As studies progressed and expanded, the need for supporting meteorological data grew correspondingly. Gradual expansion of a meteorological monitoring network has occurred as project funds have allowed. Rainfall, which can vary dramatically throughout a watershed, is an essential variable in estimating runoff. Predictive watershed computer models require actual precipitation data. Elements of the surface water budget, such as evaporation, benefit from meteorological measurements of temperature, wind velocity, and relative humidity. Finally, studies of odors associated with dairies required meteorological data such as wind speed and direction, air temperature, and relative humidity. Although no odor studies are currently in

11

Meteorological Data for Erath and Northern Hamilton Counties, Texas

progress, these sites were maintained into the year 2000. Data from these sites were recorded in support of ongoing projects and in anticipation of future project needs.

This is the ninth in a series of meteorological data reports intended to document the installation and operation of meteorological data collection sites and to provide the meteorological data stored in digital format. This report provides meteorological data from 1 January through 31 December 2001. The database contains data from 15 January 1993 through 31 December 2001. Data users may range from scientists in the environmental and agricultural communities to amateur meteorologists.

Meteorological Station Installation and SitingSite names describe the station at which the monitoring equipment is located. Site names beginning with the designation Met are sites at which only meteorological data are collected. Sites with two alphabetic characters followed by three numbers, e.g., SP020, are associated with automated water quality monitoring stations and are given the same name as the surface water sampling location. The exceptions are NF035 and SF035. These sites were originally automated storm water sampling sites and have been relegated to rainfall monitoring only. Site prefixes, e.g., SF, NF, IC, and SP, refer to specific subwatersheds.

Latitude and longitude, determined by Trimble Navigation global positioning system (GPS) equipment, and installation and termination date of each site are listed in Table B-1. As studies are completed and new studies initiated, automated monitoring sites have been and will be abandoned or relocated. Although these changes have resulted in moving rain gauge locations, efforts have been and will continue to be made to maintain comprehensive rainfall data collection in the UNBR watershed.

Siting of the stations was determined by data requirements for TIAER water and air quality monitoring studies. The rain gauge sites were selected to achieve relatively uniform coverage of the UNBR watershed, when supplemented with five National Weather Service rainfall observation sites in the watershed or immediate area. All rain gauges were positioned to avoid interference from overhead obstructions. Meteorological towers were positioned to limit interference by obstructions, such as buildings or trees. As a precaution, towers were located at a distance equal to at least ten times the height of nearby obstructions.

On 1 January 2001, TIAER was operating a total of 17 meteorological data stations, all of which were rainfall only or rainfall associated with automated sampling stations. No meteorological towers were operating at the beginning of 2001. The operating history of rainfall collection sites is detailed in previous meteorological data reports, three of which (TR9411, WP9604, and WP9803) are currently available for download through the TIAER Web site at http://www.tiaer.tarleton.edu. Rainfall recording sites outside the UNBR in the lower Bosque River watershed operating in 2001 include:

• TC020, near Crawford, Texas in Coryell County

• Met25 near Fairy, Texas in Hamilton County

• Met30 in Moshiem, Texas in Bosque County

• Met23, near Iredell, Texas in Bosque County

Monitoring EquipmentRainfall at all sites is measured with Campbell Scientific, Inc. TE525 tipping bucket rain gauges. Meteorological data at all sites designated Met and at site NF035 are quantified and recorded in either a Campbell Scientific, Inc. CR10 datalogger (Met15 only) or a Global Water model RG780 rain logger. At Sites IC020, SP020, SF035, GB040, PH002, and TC020 rainfall data are recorded in the datalogger module of ISCO 3230 or 4230 bubbler flow meters.

Electrical power is provided by Campbell Scientific, Inc. MSX5 solar panels at Met15. At sites associated with automated water samplers, power is supplied by 12-volt deep-cycle marine batteries charged by MSX5 solar panels. An internal, replaceable 9-volt lithium battery powers the RG780. Manufacturers specifications for each instrument are listed in all preceding meteorological reports.

Scheduled maintenance is performed at least weekly at sites associated with ISCO samplers and biweekly at the Met sites and NF035 and SF035. All necessary adjustments are performed during the scheduled maintenance. Data are retrieved biweekly from all sites using laptop computers. All data are returned to TIAER and stored on a UNIX workstation network using SAS software for storage and analysis.

The continuity of data collection for each site is shown in Figure A–1. This report will be updated annually to reflect additional data collected through ongoing TIAER studies.

Data CollectionAccumulated rainfall intensity is recorded at 15-minute intervals at all sites. At appropriately instrumented sites, wind speed and direction, relative humidity, and temperature are recorded hourly.

Data collection began at the first site, Met16, on 15 January 1993. At the end of 2001, 13 UNBR sites and 4 ancillary sites were recording rainfall data. As expected, gaps occur in the data due to severe weather, bovine or wildlife interference, and equipment malfunctions. As problems have been identified, steps have been implemented to improve data collection. Biweekly equipment inspection and downloading has helped to reduce data loss. Electrical grounding of all equipment, moving or fencing around sites that are accessible to livestock, and adding guy wires for stabilization have resulted in more consistent data collection. The nine-volt lithium batteries used in the RG780 data loggers were touted to have an effective life of 12 months, however it was noted that, at times, failures began as early as nine months. To decrease data loss due to battery failure, routine replacement at six-month intervals was adopted in November 2001. Although equipment malfunctions and other unanticipated events still occur, their frequency and duration have diminished as a result of corrective and preventive measures.

In July 1994 additional steps were taken to increase quality assurance (QA) of the rainfall data. At this time, TIAER field personnel installed basic plastic rain gauges at

13

Meteorological Data for Erath and Northern Hamilton Counties, Texas

all sites. Since the installation of these gauges, rainfall data collected in these gauges are recorded each time the site is visited. At sites not associated with automatic stream monitoring (ISCO instrumentation), QA data are retrieved biweekly, which corresponds to the schedule for downloading data from the Campbell data loggers. Recognizing that some evaporation occurs between readings, these stationary gauges still provide information that allows a rough check of the accuracy of the electronically recorded rainfall. At sites where ISCO flow meters are used to log rain data, visitations occur at least weekly, corresponding to our general maintenance schedule for automated gauging stations. During rainfall events, QA gauges are checked and emptied daily coinciding with sample retrieval. Additional quality control measures, initiated in 1997, were to perform test tips each time the sites are downloaded and to maintain a record sheet that is updated following each test. QA measures continued through 2001.

Data Access and PresentationThe TIAER rainfall database contains a total of 113,417 nonzero records of data collected between 15 January 1993 and 31 December 2001. The TIAER meteorological database contains approximately 198,270 records of meteorological data other than rainfall, collected from five sites for that same period. The data presented in this report were collected from 1 January 2001 through 31 December 2001. Data prior to these dates are presented in the following reports published by TIAER, Tarleton State University:

• Meteorological Data for Erath and Northern Hamilton Counties, Texas, January 1993 through January 1994, TIAER Technical Report 9411 (Jones, 1994),

• Meteorological Data for Erath and Northern Hamilton Counties, Texas, January 1994 through December 1994, TIAER Technical Report, 9601 (Jones, 1996),

Data are available in digital format as a comma-delimited ASCII file for use with an IBM PC or compatible microcomputers running under MS-DOS. (These data are also accessible at the TIAER Web site at http:www.tiaer.tarleton.edu). Data are stored in one of two databases:

14

Meteorological Data for Erath and Northern Hamilton Counties, Texas

• TIAER.RAIN includes date and time, site code, and rainfall in inches.

• TIAER.MET includes date and time, site code and, for the three meter and nine meter levels, temperature, relative humidity, wind direction, wind speed, and standard deviation of wind direction and speed.

Table B-2 lists the order of occurrence of the variables that constitute one record of the TIAER.RAIN database. Table B-3 lists the order of occurrence of the variables that constitute one record of the TIAER.MET database. Table B-4 through B-15 list daily rainfall recorded at each site from 1 January, 2001 through 31 December, 2001.

For convenience, monthly isohyets are included to graphically illustrate the spatial distribution and variability of rainfall throughout the UNBR watershed (Figures A-2 through A-13). The isohyets were developed using not only monthly rainfall totals recorded at each TIAER rain gauge, but also from data recorded by National Weather Service (NWS) rainfall observers in and near the UNBR watershed. Monthly totals reflecting questionable or partial rainfall data are not represented on isohyets. Totals for these months are indicated as ND (no data). NWS observer data from October through December 2001 are provisional, that is, unvalidated. The isohyet maps were produced using an ArcView geographic information system (GIS).
