| LI-200 | Global Horizontal | W/m2 | 10/12/2001 | - | PY37627 | 10.35 W/m2/mV |
| Measured using a LICOR LI-200 Pyranometer. | ||||||
| LI-200 | Diffuse Horizontal | W/m2 | 10/12/2001 | - | PY37627 | 10.35 W/m2/mV |
| Measured using the above LI-200, when band rotates every minute and blocks the sun. | ||||||
| (calc) | Direct Normal | W/m2 | 10/12/2001 | - | - | - |
| Calculated using Global and Diffuse measurement. | ||||||
| ? | Temperature | oC | 10/12/2001 | - | - | - |
| Outside air temperature | ||||||
| RTD | PY Temperature | oC | 10/12/2001 | - | - | - |
| Temperature of LICOR LI-200 Pyranometer measured by an RTD using a 3-Wire Half Bridge. | ||||||
| (calc) | Zenith Angle | o | 10/12/2001 | - | - | - |
| Solar zenith angle calculated by RSP datalogger program. | ||||||
| (calc) | Airmass | - | 10/12/2001 | - | - | - |
| Airmass (pressure corrected) calculated by RSP datalogger program. | ||||||
| - | RSP Battery Voltage | V | 10/12/2001 | - | - | - |
| The RSP Battery powers the datalogger and the shadowband, it is charged by a PV panel. | ||||||
| - | Switch Voltage | V | 10/12/2001 | - | - | 0.001 |
| The voltage reading of an unknown switch. | ||||||
| - | DHI Correction | W/m2 | 10/12/2001 | - | - | - |
| Diffuse Horizontal Correction Offset. | ||||||
| - | C (DNI) | - | 10/12/2001 | - | - | - |
| Direct Normal Correction Factor to account for slow time varying diffuse. If C > 1, then diffuse is dropping. | ||||||
| - | Fα, FA, FB, FC | - | 10/12/2001 | - | - | - |
| Factors used to correct global, which is a combination of the King Correction Algorithm and an algorithm to eliminate the "cat ear" effect of Li-Cor sensors at low angles. | ||||||
| - | Well Width | Index | 10/12/2001 | - | - | - |
| When shadowband rotates, the CR10X measures the LICOR sensor in burst mode (very high sample rate), when the band blocks the light a "well" in the irradiance level is created. The well width is the number of readings that were taken when the LICOR is shaded by the shadowband. | ||||||
| - | Minimum Address | Index | 10/12/2001 | - | - | - |
| The CR10X memory address defining the location of a minimum. | ||||||
| - | Error Flag | counts | 10/12/2001 | - | - | - |
| Error flag counter for instrument errors. This must be reset to zero manually after a problem occurs. | ||||||
