# NOAA Storm Events Database 1950–Present

Every storm event recorded by the NOAA National Centers for Environmental
Information (NCEI) since 1950 — cleaned, structured, and linked across
3 relational tables. 1.94 million+ events covering tornadoes, floods,
hurricanes, hail, lightning, and 58 other event types across all US states
and territories. $662 billion in total documented damage.

**This repository contains a 1,000-row sample of the Details table (Public Domain).**
Full dataset (all 3 tables — Details, Fatalities, Locations — in CSV + Parquet)
available at [claritystorm.com/datasets/noaa-storm-events](https://claritystorm.com/datasets/noaa-storm-events).

## Quick Start

```python
from datasets import load_dataset
ds = load_dataset("claritystorm/noaa-storm-events")

import pandas as pd
df = pd.read_csv("sample_1000.csv")
print(df["EVENT_TYPE"].value_counts().head(10))
print(df.groupby("YEAR")["DEATHS_TOTAL"].sum())
```

| DEATHS_TOTAL | int | Total fatalities (derived) |
| INJURIES_DIRECT | int | Direct injuries |
| INJURIES_INDIRECT | int | Indirect injuries |
| INJURIES_TOTAL | int | Total injuries (derived) |
| DAMAGE_PROPERTY_USD | float | Property damage in USD (parsed from NOAA strings) |
| DAMAGE_CROPS_USD | float | Crop damage in USD (parsed from NOAA strings) |
| TOTAL_DAMAGE_USD | float | Total damage in USD (derived) |
| MAGNITUDE | float | Storm magnitude (wind speed, hail size, etc.) |
| BEGIN_LAT | float | Begin latitude |
| BEGIN_LON | float | Begin longitude |
| END_LAT | float | End latitude |

## Tables in Full Dataset

- **details** (~1.94M rows) — one row per storm event with type, location, damage, and casualties
- **fatalities** (~23.8K rows) — one row per fatality with age, sex, and location
- **locations** (~1.75M rows) — one row per affected location with county and coordinates

All three tables join on `EVENT_ID`.
