NOAA Climate Weather Station at ACNW
The Audubon Center of the North Woods is proud to be a part of the U.S. Climate Reference Network (CRN), developed by National Oceanic and Atmospheric Administration (NOAA) scientists to improve the ability of America’s decision-makers to form policies about programs impacted by climate variability and change. Through a network of climate stations across the country, the primary goal of CRN is to provide data to be used in operational climate monitoring activities and for placing current climate anomalies into an historical perspective long-term homogeneous observations of temperature and precipitation that can be coupled to long-term historical observations for the detection of present and future climate change.
NOAA’s Geostationary Operational Environmental Satellites transmit the data received from our ground-based station in near real-time to the NOAA Climatic Data Center (NCDC) in Asheville, N.C. NCDC posts the observations online in near real-time to users around the world. Every CRN observing site is equipped with a standard set of sensors, a data logger and a satellite communications transmitter, and at least one weighing rain gauge encircled by a wind shield. Off-the-shelf commercial equipment and sensors are selected based on performance, durability, and cost. Highly accurate measurements and reliable reporting are critical.

The sensors are placed on a typical 3 meter (10 ft.) instrument tower at 1.5 meters (4.5 ft.) above the surface of the ground. Locations which experience high snowfall and snow depth are given special consideration.
The hourly observations and the fifteen minute precipitation data are stored in a data logger attached to the tower. A GOES satellite transmitter sends the data to the National Climatic Data Center where the data undergo a quality control check and are placed on the Web several times a day.
The instrument system is designed with the capacity for future expansion to accommodate additional sensors, such as soil moisture, soil temperature, atmospheric pressure, and wind speed/direction at the standard 10-meter height. The design allows for future additions of sensors on the tower without disrupting the physical site.
