There are many ways to do this. The ice sheets are very remote places, so remote sensing methods are heavily relied upon. Satellite altimeters very precisely measure the distance between the satellite and the surface of the earth, and a temporal record gives changes in the elevation of the land, and therefore the ice sheet (with terms such as isostatic rebound accounted for). Passive microwave sensors are extremely good at detecting the onset of melt in the spring. They measure radiation emitted from the ice sheet in the microwave part of the spectrum, which is very sensitive to the transition from ice to water. This gives useful information about the spatial and temporal characteristics of ice melt, especially onset. Also, visible sensors can be used to some extent.
Much of the remaining work is done on the ground. Since melt water has to go somewhere, runoff is measured at the edge of glaciers at certain spots near the ice edge, and this provides a useful gauge of how melt is changing through time. Mass balance studies are also carried out on the ice sheet through snow pits and transects, for example, to see how the surface is changing in spot measurement. Radars are sometimes used on the ground to give an image of the ice sheet and can be compared to past data.
All of this data is often integrated into computer models that simulate, given these data and others such as heat fluxes and precipitation, how the ice sheet has been behaving and is likely to change in the future. Ground data serves as the validation for this.
Glaciers are typically measured in meters or kilometers for length, and in square kilometers for area. Ice volume is often measured in cubic kilometers or cubic miles, and the mass of glaciers can be expressed in metric tons or gigatons. Temperature changes in glaciers are measured in degrees Celsius or Fahrenheit.
That depends what aspect of the glacier you want to measure. For example:
- Length or width might be measured in meters or kilometers.
- Volume might be measured in cubic meters.
- Temperature might be measured in Kelvin, or in degrees centigrade.

Different units used in measuring and different tools for measuring objects?
Units of measurement include meters for length, grams for mass, and liters for volume. Tools for measuring objects include rulers for length, scales for mass, and beakers for volume.
What is the SI unit of measurement scale?
The SI unit of measurement scale is the International System of Units, which is the modern form of the metric system used in most countries around the world. It provides a consistent and standardized set of units for measuring physical quantities such as length, mass, and time.
What units are commonly used for measuring volume in the metric system What tool is commonly used for measuring liquid volumes in the metric system?
Common units for measuring volume in the metric system are milliliters (mL) and liters (L). The tool commonly used for measuring liquid volumes in the metric system is a graduated cylinder.
What is the best unit measurement to measure a alligator?
The best unit of measurement to measure an alligator is in feet or meters, as these units are commonly used for measuring the length of large animals.
What does Watts Kilowatts and Megawatts mean to the average user?
Watts, kilowatts, and megawatts are units of power measurement. Watts are small units, commonly used for measuring the power consumption of small electronic devices. Kilowatts are larger units, used for measuring household electricity consumption or the power output of a car engine. Megawatts are even larger units, typically used for measuring the power output of power plants or large industrial facilities.
What is the standard metric unit used for types of measurement?
There are several standard metric units, for measuring different things.There are several standard metric units, for measuring different things.There are several standard metric units, for measuring different things.There are several standard metric units, for measuring different things.

How many milliliters can a prism hold measuring 2x4x3?
The measurement of the prism are given in terms of units buut there is no infromation on the units used. It is therefore impossible to answer the question.

What unit of measurement would be best for measuring the distance from North Pole to the equator?
The unit of measurement that would be best for measuring the distance from the North Pole to the equator is kilometers (km) or nautical miles (nmi). These units are commonly used to measure long distances and are suitable for measuring the Earth's surface.
What unit of measurement used in measuring large object and long distance?
Meters; for larger distances or sizes, kilometers. In astronomy, the following non-SI units are often used: astronomical units; light-years; parsecs.
What measurement is used for measuring rainfall?
Centimeters
What is 62 converted to?
The answer may depend on the measurement units used for 62 and what units the measurement is converted to. Alternatively, it could depend on what function is operating on 62 as an input value.The answer may depend on the measurement units used for 62 and what units the measurement is converted to.

What unit of measure was used in Ancient Greece?
The unit of measure commonly used in Ancient Greece was the "artaba" for measuring volume and the "cubit" for measuring length. The Greeks also used units like the "stade" for measuring distance and the "minae" for measuring weight.
