Air Quality & Meteorology (TsFile format)

Original dataset: https://huggingface.co/datasets/neuralsorcerer/air-quality

This dataset is a conversion to TsFile format of the Hugging Face dataset neuralsorcerer/air-quality, with data content identical to the original.

  • Original dataset: neuralsorcerer/air-quality (DOI: 10.57967/hf/5729)
  • Original author: neuralsorcerer (Hugging Face)
  • License: cc0-1.0 (public domain)

Conversion Notes

  • The original dataset is a single CSV (air_quality.csv) from a single station (Kolkata); the conversion outputs one TsFile (train.tsfile), neither merged nor split.
  • No TAG: single station, single series; datetime is globally unique and strictly monotonic (constant 1-hour interval), so there is no natural device dimension and all columns are FIELD.
  • The original datetime (IST / UTC+5:30 local time, no timezone suffix in the CSV) is parsed at its local wall-clock literal value into the TsFile Time column (INT64, millisecond precision) with no timezone offset; read-back times match the original CSV exactly.
  • All 10 variables are kept as DOUBLE.
  • No columns or rows dropped (all 87,672 rows retained).

Air Quality & Meteorology Dataset

The following is the original dataset description, kept verbatim.

Dataset Description

This corpus contains 87,672 hourly records (10 variables + timestamp) that realistically emulate air-quality and local-weather conditions for Kolkata, West Bengal, India. Patterns, trends and extreme events (Diwali fireworks, COVID-19 lockdown, cyclones, heat-waves) are calibrated to published CPCB, IMD and peer-reviewed summaries, making the data suitable for benchmarking, forecasting, policy-impact simulations and educational research.

The data are suitable for time-series forecasting, machine learning, environmental research, and air-quality policy simulation while containing no real personal or proprietary information.

File Information

File Records Approx. Size
air_quality.csv (original) / train.tsfile (converted) 87,672 (hourly) ~16 MB

(Rows = 10 years × 365 days (+ leap) × 24 h ≈ 87.7 k)

Columns & Descriptions

Column Unit / Range Description
datetime ISO 8601 (IST) Hour start timestamp (UTC + 05:30). In TsFile it becomes the Time column (INT64 milliseconds).
pm25 µg m⁻³ (15–600) Particulate Matter < 2.5 µm.
pm10 µg m⁻³ (30–900) Particulate Matter < 10 µm.
no2 µg m⁻³ (5–80) Nitrogen dioxide, traffic proxy.
co mg m⁻³ (0.05–4) Carbon monoxide.
so2 µg m⁻³ (1–20) Sulphur dioxide.
o3 µg m⁻³ (5–120) Surface ozone.
temp °C (12–45) Dry-bulb air temperature.
rh % (20–100) Relative humidity.
wind m s⁻¹ (0.1–30) 10 m wind speed.
rain mm h⁻¹ (0–150) Hourly precipitation.

In TsFile, datetime is the Time column (INT64 milliseconds) and the remaining 10 columns are FIELD (DOUBLE).

Intended Use Cases

  • Environmental Research — seasonal/diurnal pollution dynamics, meteorological drivers
  • Machine-Learning Benchmarks — forecasting, anomaly-detection, imputation
  • Policy / "What-If" Simulation
  • Extreme-Event Studies — Diwali spikes, cyclone wash-outs, heat-wave ozone episodes
  • Teaching & Exploration
