Below is a trace* of a balloon flight as it climbs up through the atmosphere. It shows high humidity in the first few kilometres of the atmosphere where clouds would be. A humidity reading over 75% usually indicates the presence of cloud.
trace"1. In general, an unmeasurable (less than 0.01 in.) quantity of precipitation. 2. An insignificantly small quantity. 3. The record made by any self-registering instrument.
Trace (of Precipitation) - an amount of precipitation less than 0.005 inches

Trace
A trace of rain is reported by rainfall observers when a little precipitation can be seen in the rain gauge, but there is less than 0.1 mm in total.
Trace
A rainfall amount less than 0.01".
A hydrograph or similar plot for an extended-range time horizon showing one of many scenarios generated through an ensemble forecast process.
Trace of Icing: Ice becomes perceptible on an aircraft. The rate of ice accumulation is slightly greater than the rate of sublimation.
TRACE
Generally, an unmeasurable or insignificant quantity. A precipitation amount of less than 0.005 inch.
TRACE- Less than 0.01 inches of precipitation
TRIGGER MECHANISM- A trigger mechanism is any process that initiates precipitation or storm development.
TRACE -Precipitation amounts less than 0.01".
TRADE WINDS - Persistent tropical winds that blow from the subtropical high pressure centers towards the equatorial low.

The mean molar mass of air is 28.97 g/mol. Note that the composition figures above are by volume-fraction (V%), which for ideal gases is equal to mole-fraction (that is, fraction of total molecules).
Tracer
1. A chemical or thermodynamic property of the flow that is conserved during advection. It can be used to track air-parcel movement and to identify the origins of air masses.
TRACE - A very small amount of something. Usually depicts a quantity less than the minimum amount most commonly used. In rainfall less than 1/100 of an inch is considered TRACE. In a mixture breakdown, than 1% may also called TRACE.
A continuous trace of air pressure variation with time, typically produced by a barograph.

The lens of the camera forms an image of the sun which is reflected by the hemispherical mirror so that as the sun moves across the sky, the image traces an arc of a circle on the photographic paper.

Snow FlurriesSnow flurries are an intermittent light snowfall of short duration (generally light snow showers) with no measurable accumulation (trace category).
"Light" (R-) means it is greater than a trace and up to 0.10 inch an hour. "Moderate" (R) means the rate of fall is between 0.11 to 0.30 inch per hour. "Heavy" (R+) means over 0.30 inch per hour.
Trace Of Precipitation: Less than .01 inch.
Trace Of Snowfall: Less than .1 inch.
Transmissometer: An instrument for determiming runway visibility located at the end of an airport runway.
The atmosphere, composed mainly of nitrogen and oxygen with traces of carbon dioxide, water vapor, and other gases, acts as a buffer between Earth and the sun.

air - Mixture of gases forming the earth's atmosphere, consisting of nitrogen (~78 percent), oxygen (~21 percent), water vapor, and other trace gases such as carbon dioxide, helium, argon, ozone, or various pollutants.
Ozone is found in trace quantities in the Earth's atmosphere at all times, ...
The 250 mb charts never showed any considerable trace of Isabel. Surface winds gave little clue to its progress, so mid-level winds must have been the dominant influence.
For a tilting-siphon rain gauge, the rainwater in a collector displaces a float so that a marking pen attached to the float makes a continuous trace on the paper.
Greenhouse Effect: A popular term used to describe the effects of gases such as water vapour, carbon dioxide and other trace gases (collectively known as the greenhouse gases) in keeping the Earth's temperature warmer than it would be otherwise.
Originally written nearly half-a-century ago; the most recent revision I can trace is dated 1962. Therefore it will not be found except via libraries, second-hand bookshops and personal collections.
Weightless particles are used to trace the air motion within a supercell. Blue balls are sinking and orange balls are rising.

Barometer An instrument used to monitor variations in air pressure. See also mercury barometer and aneroid barometer.
2. Snow flurries - light snow falling for short durations. No accumulation to a light dusting (or trace) is expected.
3. Snow showers - snow falling at varying intensities for brief time periods. Some accumulation is possible.
