Tools & Packages

Open-source tools for climate-health data processing, harmonization, and reproducible analysis.

Why We Build Tools

A central goal of CGHI is getting robust climate and environmental data into the hands of health and global health researchers who may have little or no familiarity with climate data — and doing so in a way that is efficient, well-structured, reproducible, understandable, and practically useful for research and intervention.

The tools below are developed and maintained as part of CGHI’s analytic infrastructure effort. They are designed to lower the barrier to working with climate data and to promote reproducible, well-documented workflows across the observatory network and beyond.

weathertools

RMIT

Fast, reproducible, hard to mess up

Transforms raw weather data columns into clean, analysis-ready variables without requiring meteorological expertise. Handles derived comfort/stress metrics, wind operations, pressure utilities, and unit management.

Key Features

  • Heat Index, Wet-bulb, Dew Point, Windchill calculation
  • Circular wind direction averaging
  • Automatic unit detection and conversion (C/F/K, Pa/hPa, etc.)
  • Station pressure and sea-level pressure corrections
  • Designed for researchers who are not meteorologists

dataplane

RMIT

Self-describing data that travels well

Creates self-describing Parquet files and Arrow datasets with embedded metadata — column meaning, units, and storage quirks — so files remain self-documenting as they move between projects, machines, teams, and time.

Key Features

  • Embedded data dictionaries in Parquet files
  • Unit tagging, validation, and conversion
  • Scaled integer encoding for compact storage
  • Multi-file Arrow dataset support
  • Automatic spec detection on read
