# CIMIS CLI

Query California Irrigation Management Information System (CIMIS) data using the `cimis` command-line tool.

## Prerequisites

```bash
cimis --version
cimis auth status
```

## Authentication

- API key from CIMIS
- Environment variable: `CIMIS_API_KEY`

## Weather Stations

```bash
cimis stations list --active
cimis stations get STATION_ID
cimis stations nearby --zip 95354 --radius 50
```

## Weather Data

### Daily Data

```bash
cimis data daily --station 171 --start 2024-06-01 --end 2024-06-30
cimis data daily --station 171 --days 7 --fields eto,humidity,temp
```

### Hourly Data

```bash
cimis data hourly --station 171 --date 2024-06-15
cimis data hourly --station 171 --start 2024-06-01T00:00 --end 2024-06-01T23:59
```

## ET0 & Irrigation

```bash
cimis eto --station 171 --start 2024-06-01 --end 2024-06-30 --crop coef
cimis waterbudget --station 171 --crop alfalfa --start 2024-06-01
```

## Export & Analysis

```bash
cimis export --station 171 --start 2024-01-01 --end 2024-12-31 --format csv
cimis summary --station 171 --month 6 --year 2024
```

## Agent Best Practices

1. **Station selection**: Use `nearby` for location-based queries
2. **Date formats**: ISO 8601 or YYYY-MM-DD
3. **Fields filtering**: Request only needed fields for faster queries
4. **Units**: Default is metric; use `--imperial` for US units
