Description
Mean diurnal range describes the average difference between each day’s maximum and minimum temperature.
Mean diurnal range describes the average difference between each day’s maximum and minimum temperature.1
This calculator uses aligned daily measurements rather than subtracting an overall period minimum from its maximum.
When to use Diurnal Temperature Range Averager
Use this tool to apply the stated diurnal temperature range averager operation with an explicit input and unit basis.
How to use Diurnal Temperature Range Averager and how it works
- Establish the measurement basis and units described above.
- Enter actualDailyMaximumTemperaturesC, actualDailyMinimumTemperaturesC and run the tool.
- Read result.value using the output meanings below.
- If input is rejected, correct the stated type, range, ordering or alignment issue and rerun; review successful results under the declared convention.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| actualDailyMaximumTemperaturesC | Daily Maximum Temperatures C. Units, ordering and applicable branch are specified in the algorithm. | array of number | required; dense; align related rows as specified; further conditions in the algorithm |
| actualDailyMinimumTemperaturesC | Daily Minimum Temperatures C. Units, ordering and applicable branch are specified in the algorithm. | array of number | required; dense; align related rows as specified; further conditions in the algorithm |
Require aligned nonempty finite maximum and minimum series and reject any day whose maximum is below its minimum. Average their daily differences; matched units, dates and completeness are caller responsibilities.
meanDiurnalRange = mean(Tmax[i]−Tmin[i]) Apply the declared units, ordering and branch conditions.
| Output field | Meaning | Value type |
|---|---|---|
| result | Object containing the declared output fields. | object |
| result.value | Mean daily maximum-minus-minimum range in the supplied temperature unit. | number |

}Limitations and assumptions
The output applies the declared operation to the values you supply. Establish the measurement basis, units, coefficients and any caller-selected rules before interpreting it. The tool does not independently collect or verify observations or decide whether a model or reference applies.
Supply explicit required fields with the documented types and dense aligned arrays. Unknown fields, wrong types and nonfinite numbers are rejected. Branch-specific constraints are explained above. A returned boolean, signed difference or tied result follows the stated convention; an input error instead means the required input contract was not satisfied. Very large inputs or outputs may be rejected by shared resource limits.
Alternative or Complementary methods
For a related operation, use Isothermality Percent Calculator. Isothermality compares mean monthly day–night variation with annual temperature variation.
For a related operation, use Annual Temperature Range Extractor. Annual temperature range in this monthly-mean convention is the warmest monthly mean minus the coldest.
