Atmospherics PHP library
========================

[](#atmospherics-php-library)

Constants
---------

[](#constants)

- `altitudeAdjustmentFactorTable` - Altitude adjustment factor at altitude (feet / 1000)
- `barometricPressureTable` - Standard barometric pressure (inches Hg) at altitude (feet / 1000)
- `dropTable` - currentVelocity/muzzleVelocity (feet per second / 1000)
- `speedOfSoundAtSeaLevel` - (feet per second)
- `temperatureTable` - Standard temperature (degrees F) at altitude (feet / 1000)
- `vaporPressureOfWaterTable` - Vapor pressure of water (inches Hg) at temperature (degrees F / 2)
- `weightDensityOfAirAtSeaLevel` - (pounds per cubic foot)

Functions
---------

[](#functions)

- `altitudeAdjustmentFactor(altitude)` - Adjusts from the standard altitude (sea level) to the current altitude.
- `barometricPressureAdjustmentFactor(altitude, barometricPressure)` - Compares the barometric pressure (inches Hg) at a given altitude (feet) to the standard barometric pressure at that altitude.
- `interpolateArray(array, arrayIndex)` - Takes the nearest 2 numbers in a lookup table and returns a number between them.
- `relativeHumidityAdjustmentFactor(temperature, barometricPressure, relativeHumidity)` - Compares the relative humidity (percentage) at a given altitude (feet) to the standard relative humidity at that altitude.
- `speedOfSound(altitude)` - Speed of sound (feet per second) at a given altitude (feet).
- `speedOfSoundFactor(altitude)` - The speed of sound factor compares the speed of sound (feet per second) at a given altitude (feet) to the standard speed of sound at sea level.
- `standardRelativeHumidity(altitude)` - Compares the relative humidity (percentage) at a given altitude (feet) to the standard relative humidity at that altitude.
- `temperatureAdjustmentFactor(altitude, temperature)` - Compares the temperature (degrees F) at a given altitude (feet) to the standard temperature at that altitude.
- `weightDensityOfAir(altitude)` - Barometric pressure (inches Hg) at a given altitude (feet)

Top contributor holds 100% of commits — single point of failure

How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio. Uses a 2-year decay window.

**Popularity (30%)** — Total and monthly downloads, GitHub stars, and forks. Logarithmic scaling prevents top-heavy scores.

**Community (15%)** — Contributors, dependents, forks, watchers, and maintainers. Measures real ecosystem engagement.

**Maturity (30%)** — Project age, version count, PHP version support, and release stability.
