Mean Annual Surface Temperature Deep Cave Estimator
Actual complete365 or 366dayweighted mean surface temperature, conditional deep-cave baseline only. Not ventilation/geothermal/seasonal offset or guaranteed actual cave temperature.
Description
An annual surface-temperature mean needs complete day-weighted coverage of the declared year.
An annual surface-temperature mean needs complete day-weighted coverage of the declared year.1
That observed proxy is different from a modeled deep-cave temperature or geothermal correction.
When to use Mean Annual Surface Temperature Deep Cave Estimator
Use this tool to obtain observedAnnualDayWeightedSurfaceTemperatureKelvin from the supplied records using the stated calculation. Establish the survey or observation scope, reference frame, units and independently applicable calibration or qualified plan.
How to use Mean Annual Surface Temperature Deep Cave Estimator and understand its results
- Establish the survey or observation scope, reference frame, units and independently applicable calibration or qualified plan.
- Enter actualFullYearSurfaceTemperatureKelvinMeans, actualRepresentedDays, using the field meanings and rules below, then run the tool.
- Read result.observedAnnualDayWeightedSurfaceTemperatureKelvin. Use the units and sign conventions below, and review any unknown records separately.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| actualFullYearSurfaceTemperatureKelvinMeans | Actual full year surface temperature kelvin means | list of number | Required |
| actualRepresentedDays | Actual represented days | list of number | Required |
Supply nonempty aligned positive temperature means in kelvin and integer represented-day counts from one through 366. Counts must sum to exactly 365 or 366. Compute a day-weighted annual surface mean. Completeness and disjointness are caller-established; the tool does not read dates or apply geothermal/depth correction.
annualSurfaceMeanKelvin=Σ(temperature_i×days_i)/Σdays_i Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Qualified observed calculation or explicit reference | object |
| result.observedAnnualDayWeightedSurfaceTemperatureKelvin | Day-weighted surface-temperature mean across the supplied complete annual coverage. | number |

}Limitations and assumptions
The actual observation coverage, calibration and qualified plan determine applicability. A numerical result does not establish survey accuracy, route suitability, atmosphere conditions or equipment adequacy beyond the declared comparison.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Lists and matrices must be dense, without missing cells. Numeric lists allow at most 10000 entries, subject to the narrower lengths and code rules above. Extremely large composite outputs are rejected.
Alternative or Complementary methods
For a related step, use Cave Temperature Stability with Depth Predictor: Depth-specific cave temperature amplitude can be compared with an applicable calibration. For a complementary comparison, use Relative Humidity Condensation Point Check: A surface's temperature relative to the matched air dew point provides a thermodynamic condensation indication.
