Station Location
This weather station is located at 39° 14' 22.272" (39.23983 North) North and 76° 42' 28.613" (-76.70740 West) West about 221ft. above sea level in the southwest Baltimore, Maryland area.
Station Equipment
The station is 
powered by a Lacrosse WS-2315 wireless weather station optimally located in the backyard of my home. The station comprises of an anemometer, rain gauge and a thermo-hydro transmitter situated in optimal positions for highest accuracy possible. It is transmitted to a wireless base station within the home and then connects via serial cable to my personal computor. The PC uses Weather Display software to capture all the live data.

The Temperature / Humidity Sensor assembly is mounted inside a homemade pogoda. It is wireless and transmits approximately 60 ft. into the
basement of my home. I have made a couple of wooden sheilds to shade direct sun exposure. The pogoda and the sheild minimize the effects of solar radiation, this results in more accurate temperature readings.

The Wind anemometer and rain gauge are mounted 6 feet above the ground on a small pole adjacent to the temperature/humidity sensor on the opposite side of my yard. In the future I hope to relocate
the anemometer to a more desirable location.

About Relay, Maryland
In 1830 the first railroad track had its debut from Baltimore to Ellicott Mills which
ran 13 miles. 
The first trains were horse-drawn wagons that ran on rails made of wood.
Since the distance between the two towns was considered too long for one team of horses,
a new team, known as a relay was secured at the halfway point of the trip. The town of Relay
was given its name at the spot where the first team of horses were exchanged. Even though Peter Cooper lost the race with the Tom Thumb he started the era of the
Iron Horse on August 28, 1830 in Relay.
Benjamin Latrobe designed the Thomas Viaduct and John McCartney, an
engineer from Ohio built the bridge. Construction of the "bridge that couldn't be
built" took three years. The bridge was named the Thomas Viaduct in honor of Phillip
Thomas who was the first president of the B&O Railroad. The bridge stretches 612 feet
from Baltimore County to Howard County and is still in use today. A monument stands today,
designating government and railroad officials connected to the project.
Samuel Morse's workshop for the telegraph was located at 5128 South Rolling Road. The first commercial telegraph service opened May 24, 1844. The telegraph pole was invented at this time because the stone base of the land was too difficult to dig the normal trench for placement of the telegraph wire.
The Eighth New York and Sixth Massachusetts regiments and Cook's Boston Battery occupied Relay during the Civil War on May 5, 1861. A Civil War fort was located on the property of Margaret Bennett, where her current home is still standing after being constructed in 1800 on Gundry's Lane. In August of 1862 the 138th Pennsylvania Volunteers came to Relay. Their commander was Colonel Sumwalt. The regiment had a total of 36 officers and 820 enlisted men. They made their headquarters at the Relay House and had come to the area to protect the railroad.
Construction began on the Relay Station (Viaduct Hotel) in 1872. The gothic structure was built of Patapsco granite and trimmed in red seneca stone. The two-story porch on the river side of the hotel gave visitors a magnificent view of the Patapsco Valley and the Thomas Viaduct. Due to the decline in train travel the Relay Station was closed in 1938 after 108 years of continuous service. The station was later torn down in the 1950's. In 1964 the Thomas Viaduct was declared a National Historical Landmark.
During World War II Relay was the sight of the first conscientious objector camp in the United States. The men worked in the nearby state park and nursery.

Data Accuracy
The positioning and calibration of the weather station sensors has been carefully considered to maximize accuracy
of the readings. We use CWOP to help make sure our data is accurate. 
CWOP checks weather stations' data against one another to compare quality. This quality checker was developed by Phillip Gladstone (CW0003). Relayweather.com is automatically notified via email if any irregularities are detected. You can view today's check for this station right here.
For those looking to setup their own stations, CWOP offers a guide on station setup and quality assurance. (PDF format)
