    issues = []
    for record in records:
        # Check for missing critical data
        if 'DayAsceEto' in record.data_values:
            eto_value = record.data_values['DayAsceEto'].value
            qc_flag = record.data_values['DayAsceEto'].qc
            
            if not eto_value or eto_value == '':
                issues.append(f"Missing ETo data for {record.date}")
            elif qc_flag and qc_flag.strip() not in [' ', '']:
                issues.append(f"Quality issue for ETo on {record.date}: {qc_flag}")
    
    return issues

# Use validation
weather_data = client.get_daily_data(targets=[2], start_date="2023-01-01", end_date="2023-01-31")
issues = validate_weather_data(weather_data)
if issues:
    print("Data quality issues found:")

## 🧩 Data Models

### WeatherData
Container for weather data responses with methods:
- `get_all_records()`: Get all weather records
- `get_daily_records()`: Get only daily records  
- `get_hourly_records()`: Get only hourly records

### WeatherRecord
Individual weather data record with attributes:
- `date`: Record date (YYYY-MM-DD)
- `station`: Station identifier
- `data_values`: Dictionary of data measurements
- `scope`: 'daily' or 'hourly'

### Station

## 💡 Best Practices

### 1. API Key Security
```python
# ✅ Good: Use environment variables
import os
client = CimisClient(app_key=os.getenv('CIMIS_API_KEY'))

# ❌ Avoid: Hardcoding API keys
client = CimisClient(app_key="your-key-here")  # Don't do this!
```

### 2. Date Range Management
```python
# ✅ Good: Reasonable date ranges
from datetime import date, timedelta

# For daily data: up to 1 year
start_date = date.today() - timedelta(days=365)
end_date = date.today() - timedelta(days=1)

# For hourly data: keep it short (1-7 days)
start_date = date.today() - timedelta(days=1)
end_date = date.today() - timedelta(days=1)
```

### 3. Error Handling
```python
# ✅ Good: Comprehensive error handling
from python_cimis import CimisClient, CimisAPIError

try:
    weather_data = client.get_daily_data(targets=[2], start_date="2023-01-01", end_date="2023-01-31")
except CimisAPIError as e:
    print(f"API Error: {e}")
    # Handle error appropriately
```

### 4. Performance Optimization
```python
# ✅ Good: Request specific data items when possible
data_items = ["day-asce-eto", "day-precip", "day-air-tmp-avg"]
weather_data = client.get_daily_data(
    targets=[2, 8, 127],
    start_date="2023-01-01",
    end_date="2023-01-31",
    data_items=data_items  # Reduces response size
)
```
