Latest Badger Weather Net Schedule

**  National Weather Service Looking for a few Good Observers! **

If you love watching and documenting the weather, the Weather Service would love to use your observations as part of the forecast and warning program, and publish your observation on our website. We are looking for persons to observe, collect and report the daily maximum, minimum and ambient temperatures as well as the 24 hour precipitation amounts including snowfall and snow depth.  

The only requirement is a reasonable set of instruments including a maximum and minimum thermometer, a reliable rain gage, and a radio to report your observations to the Wisconsin Badger Weather Net.  Your instruments must be properly sited away from buildings or other structures that could influence temperature readings.  Ideally, thermometers are housed in a ventilated shelter and are located over a grassy area.  Mounting the sensor off of the north side of the house, shielded from the direct sun rays is, also, acceptable.  Rain gages are located twice the distance away from the tallest obstruction if possible.  Low cost wireless home weather stations have proven to give reasonable reports when the sensors are properly installed.  

Your observations will be used to validate model and grid point data, used in the hydrologic model for flood forecasts, used to produce text and graphic product s for the Internet, used by the mass media and by other private and government entities. Other requirements include documentation of your stations description of your station including instrument type, exact latitude, longitude, and elevation.  Observation times are between 5 and 7:15 am daily.  Questions and guidance are provided by the National Weather Service through the Wisconsin Badger Weather Net which provides the communications for the network.

Join the Wisconsin Badger Weather Net!!

The Badger Weather Net, one of the oldest and largest weather nets, runs every day from 5 -7:15 a.m. on 3984 KHz.  We collect Ground Truth weather from stations around Wisconsin and beyond and pass those reports to the NWS Sullivan office. Until recently, the only way to submit reports was on 75 meters. However, we now have added Echolink capability! Do it from your computer or via RF.  Echolink - W9YT-R. Echolink node number: 520577  This means that ANY licensed amateur, regardless of license class, can become a BWN member! If you are on the run, no problem as it takes just a minute or so to send your weather report to the Pickup operator.

If you are interested in becoming a regular member or have questions let me know and I will provide more information. Regular participating members will be given a NWS Shef Code that identifies their weather station in the NWS system.  Hope you can join this valuable public service net!

 Measuring water content of snowfall:
I was asked how to determine the water content of snow without melting it.
Well, here is one way. It turns out that 1.00 inches of water, from an official 4 inch diameter gauge, weighs 7.2 oz. (0.50 inches weighs 3.6 oz, etc.) So, if you take your 24 hour snow sample and weigh it with, say, an accurate electronic food or postal scale, you can avoid having to melt the snow to measure its water content.

Formula: (weight of sample in oz) / 7.2 oz = # inches of water.

This formula works only for 4.0 inch (inside) diameter containers- like some coffee cans.

Don't forget to brush off any snow sticking to the side of the container and subtract the dry weight of the container holding the snow sample to obtain only the weight of the sample.

Thanks for your daily participation in the Badger Weather Net!

A Little History:

Badger Weather Net (BWN) was started December 14, 1964 by a handful of Wisconsin Amateur Radio operators (HAMS). Since that time the Badger Weather Net (BWN) has provided the National Weather Service (NWS) with valuable weather observations of high/low temperatures and precipitation from across the state. This collected data is utilized for input into the river forecast model, for public and fire weather forecasts, verification of watches and warnings, for local media use, and various...more.

First Preamble for BWN:
On the 14th of December in '64
The Badger Weather Net started to soar;
Regardless of rain - snow - wind or heat
The crack of dawn is the time to meet.
CQ CQ is the call for you -
If you have weather - this net will do
To let us know your state of bliss,
If it be a deluge or a miss.
We'd like to know the temp-per-a-ture
With Max & Min and the present for sure.
Air pressure and sky are welcome too,
With how much precip. - even dew.
The net meets daily at 6 AM - 3984 if no QRM;
All legal traffic is passed with speed -
And if you really have the need -
The "short-timers" can jump in quick
And out again - slick as a flick
