*C-MAN Weather Stations*

If you live, or have visited areas, around the Great Lakes, you might have encountered a little National Weather Service “weather station” like the one in the picture. This particular one is located near the Sugar Island Ferry at Rotary Park in Sault Ste Marie. I took this picture on Thursday, March 30th when there was plenty of sunshine overlooking the St. Marys River. They don’t look like much but they provide us meteorologists (as well as mariners) with vital, current, weather information and recent history of weather conditions. Please remember, these are private, governmental properties so do not mess with the weather stations. ——- Here is a great description provided by the National Weather Service: The Coastal-Marine Automated Network (C-MAN) was established by NDBC for the NWS in the early 1980's. The development of C-MAN was in response to a need to maintain meteorological observations in U. S. coastal areas. Such observations, which had been made previously by USCG personnel, would have been lost as many USCG navigational aids were automated under the Lighthouse Automation and Modernization Program (LAMPS). In all, approximately 60 stations make up C-MAN. C-MAN stations have been installed on lighthouses, at capes and beaches, on near shore islands, and on offshore platforms. C-MAN station data typically include barometric pressure, wind direction, speed and gust, and air temperature; however, some C-MAN stations are designed to also measure sea water temperature, water level, waves, relative humidity, precipitation, and visibility. These data are processed and transmitted hourly to users in a manner almost identical to moored buoy data. In addition to the conventional method of data transmission, certain C-MAN stations are equipped with telephone modems that allow more frequent data acquisition, data quality checking, and remote payload reconfiguration or restarting. Please click on the link below to obtain a complete list of C-MAN stations not only in our area, but across the world! And if you look in the left column, you will come across additional links that are cool such as Ship Observations (neat to look at when we have high winds, etc).
