The Station is owned by the Village of Mt. Kisco and is located on the North West shore of Byram Lake, Westchester County, New York (See Map).
The station went online in March of 2003. All data from the station is
archived and available via the "Data
Archive" link on the station home page.

In addition to the current wind direction, indicated by the blue arrow, the
wind compass incorporates a wind scatter plot represented by blue bubbles. Each
bubble illustrates three pieces of information: time, wind direction and wind
speed.
A bubble
represents a previous block of average wind data, in our case, 15-minutes. If you
could see all the bubbles there would be 12, giving a total of 3 hours of data.
Temporal order is established with bubble size. The oldest data has the smallest
bubble and the most recent, the largest.
The location of a bubble relative to the N, S, E and W on
the compass indicates direction. Additionally, the bubbles distance from the
center indicates wind speed. The center being 0 mph and the outer hashed ring 10
mph. This type of plot is to determine a general wind direction and speed over a
3-hour period. The plot is most useful when glanced at, not scrutinized for individual
bubbles.

The lake temperature sensor is fixed 9.75 feet below the spillway height. Its
position relative to the surface of the lake is constantly changing with water
level. To locate it at any given moment, subtract the current lake level from
9.75 feet.

The rain data is calculated at the end of each day at midnight. A rain
event may have actually begun as much as 24 hours before the bar on the graph
appears.

The soil temperature sensor is located 10 inches below the soil surface in
the vicinity of the pump house. The overlying soil is shaded intermittently
throughout the day..

The air temperature sensor is located on the station tower approximately 8
feet off the ground and is enclosed in a solar radiation shield.

The weather page is programmed to update hourly, on the hour. You may not see new data immediately simply because the process can take a few minutes. Deviations from the hourly schedule may be due to power outages, telephone service interruption, web traffic or site maintenance.
Lake capacity is the water that is available for Village use. It is the water
that is above the intake pipe. The intake pipe is 18 feet below the release
height of the dam. Roughly 3/5 of the total lake volume, or about 1 billion
gallons, are available for Village use. Lake capacity, due to the conical shape of the
lake bottom, is greatest near the high water mark and decreases in a nonlinear
fashion as we approach the intake pipe.
