Weather balloon Weather balloon A weather or sounding balloon is a balloon (specifically a type of high-altitude balloon) that carries instruments aloft to send back information on atmospheric pressure, temperature, humidity and wind speed by means of a small, expendable measuring device called a radiosonde. To obtain wind data, they can be tracked by radar, radio direction finding, or navigation systems (such as the satellite-based Global Positioning System, GPS). Balloons meant to stay at a constant altitude for long periods of time are known as transosondes. Weather balloons that do not carry an instrument pack are used to determine upper-level winds and
Range condition scoring of rangeland. The tables differ depending upon average rainfall as well as soil type. These differences occur because the climax plant community would differ as the variables of rainfall and soil type change. The score that is computed will fall in the range of 0-25% if the range is in "Poor" Condition, 26-50% if the range is in "Fair" Condition, 51-75% if the range is in "Good" Condition, and 76-100% if the range is in "Excellent" Condition. By taking the range condition score that is determined, the researcher then can use Table 4 in the Nebraska Cooperative Extension Circular EC
