A weather station is a facility with instruments and equipment for observing atmospheric conditions to provide information for weather forecasts and to study the weather and climate. The measurements taken include temperature, barometric pressure, humidity, wind speed, wind direction, and wind precipitations amounts. Wind measurements are taken as free of other obstructions as possible, while temperature and humidity measurements are kept free from direct solar radiation, or insolation. Manual observations are taken at least once daily, while automated observations are taken at least once an hour.

The Ceiling Balloon is the smallest size of weather balloon. This balloon is mostly used by meteorologists to determine the height of the base of clouds above ground level during daylight hours. The principle behind the ceiling balloon is a balloon with a known ascent rate (how fast it climbs) and determining how long the balloon rises until it disappears into the cloud. Ascent rate times ascent time yields the ceiling height.

How are Ceiling Balloons used?

A ceiling balloon is a small, usually red, (fluted) rubber balloon commonly measuring 76 mm (3 in) across prior to inflation, inflated to ~40 cm diameter. After inflation the balloon is taken outside and released. By timing the balloon from release until it enters the cloud a ceiling height can be obtained. When correctly inflated the balloon will rise at rate of 140 m/min (460 ft/min). The bases of clouds are very rarely flat and solid, so the ceiling height is not when the balloon disappears but when the colour begins to fade. The balloon can also be used to measure the vertical visibility into a layer of fog or blowing snow. In this case the balloon will begin to fade as soon as it is released, so the vertical visibility is when the balloon disappears. If the balloon is visible for a considerable distance into the cloud layer the observer should make note of it as it is of importance to aircraft.
The ceiling balloon is a reliable, safe and simple way to get an indication of the height of clouds. However, it does suffer from some disadvantages that the observer must be aware of. Rain and wet snow may slow the ascent of the balloon, giving a falsely high ceiling and high winds and poor visibility may cause the balloon to appear to enter the cloud before it actually does. As the balloon rises at a rate of 140 m/min (460 ft/min) it will take over five minutes for the balloon to reach 700 m (2300 ft). Beyond this height the ability to follow the balloon, even with binoculars, is poor, as even the slightest movement of the eye off the balloon will almost certainly ensure that it vanishes.
At night when it is not practical to use a balloon the ceiling projector is used. However, during twilight it may be impossible to use the ceiling projector and then a pibal (pilot balloon) light may be used. This is a simple flashlight bulb attached to a battery. To charge the battery it is immersed in water for three minutes and then tied to the balloon prior to inflation. These are rarely used today.

Pilot balloons are used by meteorologists to determine the height of the base of clouds above ground level during daylight hours. The pilot balloon can also carry small payloads of up to 75 grams.

Sounding Balloons for Sale at FACTORY PRICES for Professionals. Please select from our Product range

A Sounding balloons, also known as a type of high altitude weather balloon is a balloon which carries instruments aloft to send back information on atmospheric pressure, temperature, and humidity 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).

Materials and equipment

The sounding balloon itself produces the lift, and is usually made of a highly flexible latex material (though Chloroprene may also be used). The unit that performs the actual measurements and radio transmissions hangs at the lower end of the string, and is called a radiosonde. Specialized radiosondes are used for measuring particular parameters, such as determining the ozone concentration.
The balloon is usually filled with hydrogen due to lower cost, though helium can be used as a substitute. The ascent rate can be controlled by the amount of gas with which the sounding balloon is filled. Weather balloons may reach altitudes of 40 km (25 miles) or more, limited by diminishing pressures causing the balloon to expand to such a degree (typically by a 100:1 factor) that it disintegrates. In this instance the instrument package is usually lost. Above that altitude sounding rockets are used. After sounding rockets, satellites are used for even higher altitudes.
Major manufacturers of balloons are Totex and Cosmopren of Japan, Pawan Rubber Products (Pawan Exports) of India, Kaysam (now Kaymont), and Scientific Sales, Inc. of the U.S..
Weather balloons are sometimes cited as the cause for unidentified flying object sightings, and are also used for cluster ballooning.

Sounding Balloons Launch time, location, and uses

Weather balloons are launched around the world for observations used to diagnose current conditions as well as by human forecasters and computer models for weather forecasting. About 800 locations around the globe do routine releases, twice daily, usually at 0000 UTC and 1200 UTC. Some facilities will also do occasional supplementary “special” releases when meteorologists determine there is a need for additional data between the 12 hour routine launches in which time much can change in the atmosphere. Military and civilian government meteorological agencies such as the National Weather Service in the US typically launch balloons, and by international agreements almost all the data is shared with all nations.
Specialized uses also exist, such as for aviation interests, pollution monitoring, and research. Examples include pilot balloons (Pibal). Field research programs often use mobile launchers from land vehicles as well as ships and aircraft (usually dropsondes in this case).

CANDLES

1. No tears – Wax with Wick inside

2. Purity and Firmness higher than ordinary candles

3. Long burning time (40 minutes)

LANTERNS:

1. Made of thin Cardboard and Paper

2. High: 120mm x Dia: 100mm / Handle: 110mm with thin wire

The Pilot Balloons Candles and Lanterns are used for upper wind mesurement during pilot balloons ascent at night.

When released into the armosphere with a balloon inflated with hydrogen, the candle and lantern provide an illumination for tracking with a theodolite. The Wind speed and direction are then computed using electronic calculator when the azimuth and elevation readings are taken at successive intervals of time.
