History of the GMF Weather Station
The official station name is Norfolk 2SW. The name comes from the fact that the station is two miles southwest of the U.S. Post Office in the center of Norfolk, CT. It is a National Weather Service (NWS) Cooperative Weather Observer Station, one of about 165 in Connecticut. There are currently about 11,700 cooperative stations in the United States. The station is located at the Childs family’s Coolwater estate on Windrow Road, and thus was often referred to as the Coolwater weather station. The NWS leased a small parcel of land for the station. The station’s elevation is approximately 1,340 feet. Great Mountain Forest staff currently operate and help maintain the station.
Until 2012 the station was technically classified by the NWS as being a Hydrological-type of station, one of only a few in the state. This means that in addition to temperature and precipitation, readings were also taken related to evaporation, such as wind movement, water temperature, wet bulb temperature and dry bulb temperature. These are factors used to determine evaporation rates, which are important in agriculture and forestry. After October 2011 the NWS made the decision to stop all evaporation readings (at least in CT). Norfolk 2SW was one of the last in the state to stop. Temperature and precipitation (rain and snow) observations continue to be made. When there is snow on the ground, measurements are routinely taken to determine the water content (water equivalent) of the snow. This information helps the NWS forecast the amount of runoff and potential flooding from snow melt during warm spells or the spring thaw. Every day of the year readings are taken at the station and submitted manually to the NWS. The readings are now submitted via the Internet. Prior to April 2003 the readings were submitted over the telephone. The weather observation data does not become “official” until it is reviewed and approved by the NWS.
Edward (“Ted”) Childs as a child discovered that he had an interest in the weather. It was an interest he received from his grandfather. In the early 1930’s Ted began recording weather data in Norfolk as part of his Master’s thesis for the Yale University School of Forestry. A number of stations were set up throughout his family owned forest to study the microclimatic influence of Hemlock trees. When the study was completed, Ted decided to keep-up the one station located at Coolwater and on January 1, 1932 Ted began regular daily observations at the Coolwater station. Daily observations have been made every day since January 1, 1932. In January 2021 the station will be starting its 90th continuous year of daily observations.
In 1964 the station became one of the first seven Reference Climatological Stations in the country. There were eventually twenty-one such stations located all across the country. This was the only one located on privately owned land. These special stations were used as benchmarks, meaning they were seen as places that were untouched by the ever-increasing development of the country and were seen as places that would stay that way. Unfortunately, sometime during the 1980’s the government stopped classifying these certain stations as Reference Climatological Stations and threw Norfolk 2SW into the mix with all other cooperative stations. There is still a sign on the station that classifies it as a Reference Climatological Station, a testament to the station’s historic past.
Norfolk 2SW is part of the Eastern North American Phenology Network. This program is run under the direction of the University of Wisconsin-Milwaukee. Phenology is the science of periodic biological events in the animal and plant world as influenced by the environment, especially weather and climate. Phenology has been identified as a critical contributor to global climate change research. Springtime characteristics of three Persian Lilacs planted near the weather station in 1965 have been recorded every year since 1968.
Even though it has always been a federal agency, the NWS relied heavily, as it does to this day, on voluntary Cooperative Weather Observers. Ted Childs and fellow long-time weather observer Darrell Russ received numerous awards from the NWS for their many years of service in weather observing. Among these awards, in 1992 the NWS awarded Ted the Helmut E. Landsberg Award for providing over 60 years of weather observing service. Ted also received the NWS’s Thomas Jefferson Award for his outstanding achievements in the field of meteorological observations. In 2002 the NWS awarded Darrell, who began working at Great Mountain Forest for Ted in 1950, the Edward H. Stoll Award for providing over 50 years of weather observing service. These are some of the most prestigious awards given to private citizens by the NWS. It is truly extraordinary to have had such dedicated observers spend so many years recording the weather at Norfolk 2SW. Over the long history of the station there have only been a handful of observers. Consistency in recording is critical and that is exactly what continues to take place at the station. The current weather observer of record is Russell Russ, son of Darrell. Russell took over as lead observer in April 2003.
In September 2003 an automated Davis Vantage Pro2 weather station was installed at the GMF forestry office. This weather station is used for general weather information only. It is not, and will not become, the official Norfolk 2SW weather station for the NWS. Although this automated station is not the official NWS weather station, it does aid in the educational, recreational, research and public outreach programs that are a cornerstone of the mission of the GMF. The software associated with this weather station currently transmits real-time weather data via the Internet to four weather websites. There is a link to this station in the weather section of the Great Mountain Forest website. Some local businesses are even including this station as a link on their website homepages.
In December 2004 the NWS installed a new modernized automated weather station at the GMF forestry office, a little less than a half-mile up the road from the Norfolk 2SW station. The NWS decided to install an Enhanced-type of modernized station at this site. The new modernized station contains an instrument cluster to record temperature, a precipitation gauge with heated collar to record all types of precipitation and a 10-meter tower with wind sensors. This station transmits readings to the NWS’s Hydrometeorological Automated Data System (HADS) via a signal transmitted to the Geostationary Operational Environmental Satellite (GOES). On December 20, 2004 Steve Pritchett, the second in command for the entire United States Cooperative Modernization Program, came and inspected the new station as part of a routine follow-up procedure. The NWS planned to eventually convert many of its 11,700 cooperative stations to this modernized (automated) format. As of January 2005 Norfolk 2SW was just one of ninety stations across the country that had received the modernized station format and as of August 2005 was just one of five stations across the country that have received the wind sensors.
As of October 2020, the Norfolk 2SW station located at the original location is still the official NWS station of record for Norfolk. All readings are still being taken from there and are submitted manually on a daily basis. Weather readings will continue to be taken at both the automated station, now called the HADS station, and manually at the original Norfolk 2SW station. The original plan of the NWS was to replace the old stations with the new automated HADS stations. Many years have gone by since the HADS station was installed. The NWS may be rethinking their original plan and it is not a given that the automated stations will in fact replace the older manual stations. Even with the new modernized automated station, if the NWS still would like detailed observations, a person will still need to do some weather observation tasks by hand. Tasks such as recording start and stop times for precipitation, types of precipitation (rain, sleet, snow, hail, etc…), snow depth, and a few other observations.
The GMF forestry office has on file the Norfolk 2SW weather station daily readings sheets that date back to January of 1932, and is fortunate to also have copies of some daily weather readings sheets taken by J.W. Beach of Norfolk that date back to November of 1884. This remarkable resource, utilized by numerous individuals and organizations over the years, will prove to be even more important in the future, as climate becomes more of a major concern in the world.
