Humidity Calculator: Water Vapor Measures from Temperature and Dew Point

An R package by Jun Cai provides functions for calculating six standard water vapor measures used in meteorology. It computes saturation vapor pressure, partial water vapor pressure, relative humidity, absolute humidity, specific humidity, and mixing ratio from temperature and dew point inputs. The package also includes conversion functions between these humidity measures.

Use Cases

• Calculate relative humidity for weather analysis based on temperature and dew point inputs.
• Derive specific humidity for climate modeling based on the described conversion functions.
• Compute mixing ratio for atmospheric science research based on the provided calculation methods.
• Convert between different water vapor measures for data standardization based on the package's utilities.

Strengths

• Provides calculations for six distinct water vapor measures commonly used in meteorology.
• Includes conversion functions between the calculated humidity measures.
• Functions are implemented in a dedicated R package for reproducibility.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
