## Measurement Protocols

### 3.1 Satellite Measurement Protocol

**Standard Operating Procedure**:

1. **Data Acquisition**
   - Retrieve L1B radiances from data center
   - Download ancillary data (meteorology, surface properties)
   - Check data completeness and quality flags

2. **Retrieval Processing**
   - Apply retrieval algorithm (e.g., ACOS, RemoTeC)
   - Generate XCO2, XCH4 column estimates
   - Calculate uncertainty and quality flags

3. **Quality Filtering**
   - Apply cloud screening (cloud fraction < 0.1)
   - Filter by solar zenith angle (< 70°)
   - Remove high aerosol scenes (AOD < 0.3)
   - Validate surface pressure retrieval

4. **Validation**
   - Compare with TCCON ground truth
   - Check against model expectations
   - Cross-validate between satellites

**Quality Criteria**:
```yaml
satellite_qc:
  cloud_fraction: "<0.1"
  solar_zenith_angle: "<70 degrees"
  aerosol_optical_depth: "<0.3"
  surface_type: "land or ocean"
  retrieval_convergence: true
  xco2_uncertainty: "<1.5 ppm"
  surface_pressure_error: "<2 hPa"
```

### 3.2 Ground Station Protocol

**NOAA Flask Sampling SOP**:

1. **Sample Collection**
   - Use clean, pre-evacuated flasks
   - Sample at designated times (local afternoon)
   - Record meteorological conditions
   - Duplicate samples for QC

2. **Chain of Custody**
   - Seal and label flasks immediately
   - Log sample ID, time, conditions
   - Ship to analysis lab within 7 days

3. **Laboratory Analysis**
   - Analyze within 30 days of collection
   - Run against WMO-traceable standards
   - Repeat measurements for precision check
   - Record instrument status and calibration

4. **Data Validation**
   - Check for outliers (±3σ)
   - Compare with climatology
   - Flag suspicious data
   - Document any issues

**Calibration Requirements**:
- Frequency: Monthly for in-situ, per flask for sampling
- Standards: WMO-traceable reference gases
- Traceability: Documented calibration hierarchy
- Uncertainty: ±0.1 ppm (CO2), ±2 ppb (CH4)

### 3.3 Emission Calculation Protocol

**IPCC Tier System**:

| Tier | Method | Data Requirements | Uncertainty |
|------|--------|-------------------|-------------|
| **Tier 1** | Default IPCC factors | Activity data only | ±50% |
| **Tier 2** | Country-specific factors | National factors, good AD | ±20% |
| **Tier 3** | Detailed models | Facility-level data, models | ±10% |

**Calculation Workflow**:

```python
# Tier 1 Example: Energy Sector CO2
def calculate_emissions_tier1(activity_data_TJ, fuel_type):
    """
    Calculate CO2 emissions using IPCC Tier 1 method

    Args:
        activity_data_TJ: Fuel consumption in TJ
        fuel_type: "coal", "natural_gas", "oil", etc.

    Returns:
        emissions_tCO2: CO2 emissions in tonnes
    """
    # IPCC 2006 default emission factors (kg CO2/TJ)
    emission_factors = {
        "coal": 94600,
        "natural_gas": 56100,
        "oil": 73300
    }

    ef = emission_factors[fuel_type]
    emissions_tCO2 = (activity_data_TJ * ef) / 1000  # Convert kg to tonnes

    return emissions_tCO2

# Example usage
coal_consumption_TJ = 100000  # TJ
emissions = calculate_emissions_tier1(coal_consumption_TJ, "coal")
print(f"CO2 emissions: {emissions:,.0f} tonnes")
# Output: CO2 emissions: 9,460,000 tonnes
```

**Uncertainty Estimation**:
```python
import math

def calculate_combined_uncertainty(uncertainties):
    """
    Calculate combined uncertainty using error propagation

    Args:
        uncertainties: List of individual uncertainties (as decimals)

    Returns:
        combined_uncertainty: Combined uncertainty (%)
    """
    sum_of_squares = sum(u**2 for u in uncertainties)
    combined = math.sqrt(sum_of_squares)
    return combined * 100  # Convert to percentage

# Example
activity_data_uncertainty = 0.05  # 5%
emission_factor_uncertainty = 0.10  # 10%
combined = calculate_combined_uncertainty([activity_data_uncertainty, emission_factor_uncertainty])
print(f"Combined uncertainty: ±{combined:.1f}%")
# Output: Combined uncertainty: ±11.2%
```
