atmometer
RareTechnical / Scientific
Definition
Meaning
An instrument for measuring the rate of water evaporation from a wet surface into the atmosphere.
Any device used in meteorology, agriculture, or hydrology to gauge evaporative loss, which is crucial for understanding water cycles, irrigation needs, and climatic conditions.
Linguistics
Semantic Notes
The term is highly specialized and context-bound, almost exclusively used in scientific literature related to meteorology, hydrology, or agricultural science. It is not a term used in general conversation.
Dialectal Variation
British vs American Usage
Differences
No significant differences in meaning or usage exist. The term is used identically in scientific contexts in both varieties.
Connotations
Neutral and purely technical in both regions.
Frequency
Extremely low frequency in both British and American English, limited to niche scientific fields.

Technical
The primary domain. Used by scientists, irrigation engineers, and climatologists to quantify evaporation rates.
Examples
By CEFR Level
- Scientists placed an atmometer in the field to collect data on daily evaporation.
- The study compared evapotranspiration estimates with direct measurements from a calibrated Piche atmometer.
- Accurate atmometer readings are critical for optimizing irrigation schedules in water-scarce regions.
Learning
Memory Aids
Mnemonic
Think of 'ATMO' (as in atmosphere) and 'METER' (as in measuring device). It's a meter for the atmosphere's drying power.
Conceptual Metaphor
THE ATMOSPHERE IS A SPONGE (absorbing moisture, measured by the atmometer).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid confusing with 'барометр' (barometer) or 'анемометр' (anemometer). The direct translation 'атмометр' exists but is equally rare.
Common Mistakes
- Mispronouncing it as 'auto-meter' or 'atmo-meeter' (with a long 'e').
- Confusing it with a hygrometer (measures humidity) or an anemometer (measures wind speed).

FAQ
Frequently Asked Questions
No. A hygrometer measures humidity in the air, while an atmometer measures the rate of evaporation from a surface.
Primarily researchers in meteorology, climatology, hydrology, and agricultural science, as well as irrigation engineers.
No, it is a rare, technical term unknown to the general public and seldom used outside specific scientific disciplines.
The Piche atmometer is a classic type, which uses a graduated tube and a wet porous surface to measure evaporation.
