I believe the answer you seek is the radiosonde, which is attached to a weather balloon.
A. Pilot Balloon/Theodolite
A Pilot Balloon is a meteorological balloon that is filled with gas lighter than air. When the pilot balloon is used in conjunction with a theodolite it is used to determine the speed and direction of winds at different levels of the atmosphere.
The theodolite is similar to an engineer's transit. It consists of a sighting telescope mounted so that it is free to rotate around a horizontal and a vertical axis and has graduated scales so that the angles of rotation maybe measured while tracking the pilot balloon.
The elevation angles and azimuths of the balloon are recorded from the theodolite and these data at the end of the flight which may last for more than an hour are plotted to a plotting board. The wind speed and direction at selected levels are calculated either by trigonometric methods or graphical methods.
Night observation is accomplished by attaching a lit paper lantern to the balloon.
B. Radiosonde
Radiosonde, an airborne instrument used for measuring pressure, temperature and relative humidity in the upper air is the radiosonde. he instrument is carried aloft by a meteorological balloon inflated with hydrogen. The radiosonde has a built-in high frequency transmitter that transmits data from the radiosonde meter and recorded on the ground by a specially designed radiosonde receiver.
C. Rawinsonde
A more sophisticated version of this instrument is the rawindsonde. The rawindsonde is an electronic device used for measuring wind velocity, pressure, temperature and humidity aloft. It is also attached to a balloon and as it rises through the atmosphere, it makes the required measurements.
D. Rawin
Another special instrument is the Rawin which is short for Radar and Wind. It is an electronic device that measures pressure, temperature and humidity.
E. Wind Finding Radar
Another instrument is the Wind Finding Radar. It determines the speed and direction of winds aloft by means of radar echoes. A radar target is attached to a balloon and it is this target that is tracked by ground radar. The bearing and time of interval of the echoes is evaluated by a receiver.
F. Weather Surveillance Radar
A Weather Surveillance Radar is of the long range type which detects and tracks typhoons and cloud masses at distance of 400 kilometers or less. This radar has a rotating antenna disk preferably mounted on top of a building free from any physical obstruction. Radio energy emitted by the transmitter and focused by the antenna shoots outward through the atmosphere in a narrow beam. The cloud mass, whether it is part of a typhoon or not, reflects a small fraction of the energy back to the antenna. This reflected energy is amplified and displayed visually on a radar scope. The distance or slant range of the target from the radar is determined through the elapsed time the signal is transmitted and then received as an echo. Its direction is determined by the direction at which the focused beam is pointing at the instant the echo is received. The radar is a useful tool in tracking and monitoring tropical cyclones.

Scientists study upper atmospheric conditions to?
Meteorologists study the upper atmospheric condition for the predictions of weather conditions, and the climate.
Why scientists are interested in weather conditions in upper atmosphere?
becuase scientists use several instruments to measure conditions in the upper atmosphere to obtain a better understanding of local and global weather patterns.
The conditions of the upper troposphere can be determined by using weather?
It is determined using hot air balloons.
What substance in the upper atmosphere is important to temperature changes in the upper atmospheric layers?
it is the ozone layer in the atmosphere because it is what keeps the atmosphere in check of what is happening in the atmosphere.
Conclusion of causes of typhoon?
Typhoons, also called hurricanes, are caused by high moisture, warm water, and strong wind. Other factors include upper atmospheric pressure and low atmospheric stability.
Scientists study upper atmospheric conditions to?
Meteorologists study the upper atmospheric condition for the predictions of weather conditions, and the climate.
What are the conditions for a hailstorm to occur?
There has to be cold winds in the upper atmospheric layers.
Why scientists are interested in weather conditions in upper atmosphere?
becuase scientists use several instruments to measure conditions in the upper atmosphere to obtain a better understanding of local and global weather patterns.
How did people study the upper atmosphere before there were airplanes and other sophisticated instruments?
Balloons were used in the past to record weather and atmospheric conditions at higher altitudes. In fact, the weather balloon is still considered today to be one of the most effective ways at obtaining this information.
The conditions of the upper troposphere can be determined by using weather?
It is determined using hot air balloons.
What are the instruments are used to measure the upper atmosphere?
The instruments used to measure the conditions of the upper atmosphere is a Radiosonde, Radar, Weather Satellites, and Computers.
What is trouph in science?
A trough in meteorology means a narrow elongated region of relatively low atmospheric pressure occuring at the ground surface or in the upper atmosphere and often associated with a weather front.
How are radar and weather balloons helpful in weather forecasting?
Radar is very important in weather forecasting because it can see any oncoming weather and this can be used to forecast where and when rain / storms / hurricanes are going to hit. Weather balloons are important also because they record and send down information of conditions in the upper atmosphere. This can also be used to see whether there is any weather coming and what the temperature/ air pressure is in the upper atmosphere.
What is the boundary between air masses of different temperature humidity or density called?
A 'Weather front'. A Warm front is changing the weather from cool dry conditions to warmer wet conditions., (higher humidity). A cold front is changing the weather from warmer wet conditions , to drier cooler conditions. (lower humidity , but with showers). An Occluded front is when warm air is pushed into the upper atmosphere, but will often bring rain.
Clouds owe their existence to the presence of atmospheric?
Clouds are made out of atmospheric water vapor. They form in part due to cooling in the upper atmosphere.
What is the study of the air that surrounds your planet?
The general term is `Atmospheric sciences`. Under there are several more specific areas of science. Meteorology - for atmospheric chemistry and atmospheric physics with a major focus on weather forecasting. Climatology - the study of atmospheric changes over long and short-term periods that define average climates and their change over time. Aeronomy - the study of the upper layers of the atmosphere. Sometimes the term `aerology` is used to describe the study of the earths atmosphere.
What measures average weather of an area over 25 30 years?
The measure that captures the average weather of an area over 25-30 years is called climate. Climate is determined by analyzing long-term weather data, including temperature, rainfall, humidity, wind patterns, and other meteorological factors. By studying climate data over a significant period, scientists can identify patterns and trends that help characterize the typical conditions of a particular region.
