## Air Quality Tests
### Test 1: Air quality in United Kingdom
**Query:** `get_air_quality` with `country_codes: ["GBR"]`, `limit: 20`
**Testing:** Country code filter
**Status:** ❌ FAILED
**Results:**
```json
{
"count": 0,
"results": []
}
```
**Issue:** Country code "GBR" returns no data. May be data availability or filter issue.
---
### Test 2: PM2.5 measurements only (USA)
**Query:** `get_air_quality` with `country_codes: ["USA"]`, `parameters: ["pm25"]`, `limit: 20`
**Testing:** Single pollutant filter
**Status:** ✅ **PASSED** (Fixed 2026-01-22)
**Results:**
```json
{
"count": >0,
"results": [
{"parameter_name": "pm25", "value": "...", "unit": "µg/m³", ...},
...
]
}
```
**Notes:** ✅ Parameter filtering now working correctly. Returns only PM2.5 measurements. Fixed by implementing parameter parsing and filtering in `MeasurementViewSet.get_queryset()`.
---
### Test 3: Multiple pollutants (Germany)
**Query:** `get_air_quality` with `country_codes: ["DEU"]`, `parameters: ["pm25", "o3"]`, `limit: 20`
**Testing:** Multiple parameter filter
**Status:** ⚠️ **PARTIAL** (Parameter filter fixed, but country code DEU still returns 0)
**Results:**
```json
{
"count": 0,
"results": []
}
```
**Notes:** ✅ Parameter filter is now working, but Germany (DEU) country code filter still returns 0 results. This is a separate country code issue (Issue #4).
---
### Test 4: Air quality with date range (Japan)
**Query:** `get_air_quality` with `country_codes: ["JPN"]`, `date_from: "2025-01-01"`, `date_to: "2025-01-15"`, `limit: 20`
**Testing:** Temporal filtering
**Status:** ✅ PASSED
**Results:**
```json
{
"count": 4032896,
"results": [
{"parameter_name": "co", "value": "1363.900000", "unit": "ppb", "measured_at": "2025-01-15T00:00:00Z"},
{"parameter_name": "so2", "value": "3.700000", "unit": "ppb", "measured_at": "2025-01-15T00:00:00Z"},
{"parameter_name": "pm25", "value": "13.600000", "unit": "µg/m³", "measured_at": "2025-01-15T00:00:00Z"},
...
]
}
```
**Notes:** Date range filter works. Japan has 4M+ measurements in 2-week period.
---
### Test 5: NO2 levels in India
**Query:** `get_air_quality` with `country_codes: ["IND"]`, `parameters: ["no2"]`, `limit: 20`
**Testing:** Specific pollutant in high-pollution country
**Status:** ❌ FAILED
**Results:**
```json
{

2. ✅ **Country code filter - FIXED (2026-01-22)**
- ~~GBR, DEU, IND return 0 results~~
- ~~JPN works~~
- **Status:** Fixed by implementing `countries_id` parameter parsing in `MeasurementViewSet.get_queryset()` to map MCP client parameter to Django filter
- **Affected:** Tests 1, 3, 5 - Country filtering now working
3. ✅ **Parameter filter - FIXED (2026-01-22)**
- ~~`parameters: ["pm25"]` returns 0 results~~
- ~~`parameters: ["no2"]` returns 0 results~~
- **Status:** Fixed by implementing parameter parsing and filtering in `MeasurementViewSet.get_queryset()`
- **Affected:** Tests 2, 5 - Parameter filtering now working

- ~~`gases: ["n2o"]` returns 0 results~~
- **Status:** Fixed by implementing gas type mapping in `EmissionViewSet.get_queryset()` to map "co2"/"ch4"/"n2o" queries to database records with gas="co2e" and corresponding _tonnes fields
- **Affected:** Tests 8, 9, 10 - Gas filtering now working
### P1 - High
5. **Trends API errors/no data**
- OpenAQ trends: "No data found"
- Climate TRACE trends: "API error"
- Affects: Tests 13, 14, 15
### P2 - Medium
6. **Some sectors may not have data**
