NREL Long Wave Test
This is special test of long wave (infra red) irradiance developed by NREL for the ARM Program. Required fields are as follows:
| Upwelling Long Wave Irradiance (LWup) | TF1 |
| Downwelling Long Wave Irradiance (LWdn) | TF2 |
| Direct Normal Irradiance (DNI) | CF1 |
| Global Horizontal Irradiance (GHI) | CF2 |
| Diffuse Horizontal Irradiance (DHI) | CF3 |
| DNI Flag (from SERI_QC Test) | CF1F |
| GHI Flag (from SERI_QC Test) | CF2F |
| DHI Flag (from SERI_QC Test) | CF3F |
| Minimum LWup | F1 |
| Maximum LWup | F2 |
| Minimum LWdn | F3 |
| Maximum LWdn | F4 |
Test Flags are set as follows:
| Case | TF1 Flag | TF2 Flag | F1 < TF1 | TF1 < F2 | F3 < TF2 | TF2 < F4 | CF1F = good | CF1 <= 5 | TF2 > TF1+20 | TF1 > TF2 | CF2F = good | CF3F = good | CF2-CF3 < 20 | TF1 Miss | TF2 Miss |
