Barometric Cave Breathing Amplitude Calculator
Actual sampled barometric pressure range, not air-volume exchange from pressure alone or unobserved cave-breathing maximum.
Description
Barometric pressure peak-to-peak amplitude describes the range of an observed pressure trace.
Barometric pressure peak-to-peak amplitude describes the range of an observed pressure trace.1
It does not determine cave airflow or a ventilation mechanism by itself.
When to use Barometric Cave Breathing Amplitude Calculator
Use this tool to obtain observedBarometricPressurePeakToPeakPa 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 Barometric Cave Breathing Amplitude Calculator and understand its results
- Establish the survey or observation scope, reference frame, units and independently applicable calibration or qualified plan.
- Enter actualBarometricPressurePaSamples, using the field meanings and rules below, then run the tool.
- Read result.observedBarometricPressurePeakToPeakPa. 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 |
|---|---|---|---|
| actualBarometricPressurePaSamples | Actual barometric pressure pa samples | list of number | Required |
Require a nonempty strictly positive pressure sample list in pascals. Return maximum-minus-minimum; a one-sample trace returns zero. No time coordinate, frequency analysis or airflow inference is added.
pressureAmplitudePa=max(samples)−min(samples) 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.observedBarometricPressurePeakToPeakPa | Observed Barometric Pressure Peak To Peak Pa | 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 Mean Annual Surface Temperature Deep Cave Estimator: An annual surface-temperature mean needs complete day-weighted coverage of the declared year. For a complementary comparison, use Cave Temperature Stability with Depth Predictor: Depth-specific cave temperature amplitude can be compared with an applicable calibration.
