What data do weather balloons collect?

These observations include vertical profiles of temperature, humidity, wind speed and direction, atmospheric pressure, and geopotential height.

What is radiosonde observation?

(Acronym raob.) An evaluation of pressure, temperature, and relative humidity data received from a balloon-borne radiosonde. The processed data are usually presented in terms of geopotential height, temperature, and dewpoint at mandatory and significant pressure levels.

What is the difference between a radiosonde and a Rawinsonde?

A radiosonde observation provides only pressure, temperature, and relative humidity data. When a radiosonde is tracked so that winds aloft are provided in addition to the pressure, temperature, and relative humidity data, it is called a rawinsonde observation.

Which of the following is not a measurement taken by a radiosonde?

Which of the following is not a measurement taken by a radiosonde? cloud height. A river flows from approximately 45° north latitude toward the equator, as shown in the diagram below.

How much weight can a weather balloon lift?

Regulations say flights can carry up to 12 lbs total payload weight, not including the weight of the balloon. However, the weight needs to be divided into separate payload packages that can’t be more than 6 pounds each.

How is pressure measured on a radiosonde?

Radiosondes use two main principles for determining the atmospheric pressure: one is a direct pressure measurement with a sensor; the other derives pressure from the radiosonde measurements of height from the Global Positioning System (GPS), temperature, and humidity.

What are radiosonde and dropsondes used for how are they different?

Most radiosondes have radar reflectors and are technically rawinsondes. A radiosonde that is dropped from an airplane and falls, rather than being carried by a balloon is called a dropsonde. Radiosondes are an essential source of meteorological data, and hundreds are launched all over the world daily.

What is the name of the equipment used to measure air pressure?

barometer
A barometer is a scientific instrument used to measure atmospheric pressure, also called barometric pressure. The atmosphere is the layers of air wrapped around the Earth. That air has a weight and presses against everything it touches as gravity pulls it to Earth. Barometers measure this pressure.

What is the weight of a radiosonde?

The weight of a radiosonde is typically 250 g (8.8 oz). Sometimes radiosondes are deployed by being dropped from an aircraft instead of being carried aloft by a balloon.

How high can a radiosonde fly?

A typical radiosonde flight lasts 60 to 90 minutes. One radiosonde from Clark Air Base, Philippines, reached an altitude of 155,092 ft (47,272 m). The modern radiosonde communicates via radio with a computer that stores all the variables in real time.

How do radiosondes determine wind speed?

Modern radiosondes can use a variety of mechanisms for determining wind speed and direction, such as a radio direction finder or GPS. The weight of a radiosonde is typically 250 g (8.8 oz). Sometimes radiosondes are deployed by being dropped from an aircraft instead of being carried aloft by a balloon.
