|---|---|---|---|---|---|---|---|---|---|---|---|
| 1 | Airmass | 03/08/2007 | HSU | Relative optical airmass (not pressure corrected). Calculated after datacollection (outside the datalogger) using the Solar Position Algorithm (SPA) and added to the datastream. | CA | HSU | AMASS | ||||
| 2 | Azimuth Angle | 03/08/2007 | HSU | Solar azimuth angle. Calculated after datacollection (outside the datalogger) using the Solar Position Algorithm (SPA) and added to the datastream. | CA | HSU | AZM | ||||
| 3 | 23224F3 | Diffuse Horizontal | 03/08/2007 | HSU | Diffuse (Sky) shortwave irradiance measured by a PSP mounted under a manually-adjusted shadow band. Due to the presense of the shadow band a 10% to 18% increase is needed, depending on solar declination for the day of data. Both the corrected and un-corrected diffuse data are provided. | 07/30/2009 | CA | HSU | Eppley | PSP | DHSB |
| 4 | 23214F3 | Diffuse Horizontal | 07/30/2009 | HSU | Diffuse (Sky) shortwave irradiance measured by a PSP mounted under a manually-adjusted shadow band. Due to the presense of the shadow band a 10% to 18% increase is needed, depending on solar declination for the day of data. Both the corrected and un-corrected diffuse data are provided. | 09/20/2012 | CA | HSU | Eppley | PSP | DHSB |
| 5 | 23224F3 | Diffuse Horizontal | 09/20/2012 | HSU | Diffuse (Sky) shortwave irradiance measured by a PSP mounted under a manually-adjusted shadow band. Due to the presense of the shadow band a 10% to 18% increase is needed, depending on solar declination for the day of data. Both the corrected and un-corrected diffuse data are provided. | 06/17/2016 | CA | HSU | Eppley | PSP | DHSB |
| 6 | 35369F3 | Diffuse Horizontal | 06/17/2016 | HSU | Diffuse (Sky) shortwave irradiance measured by a PSP mounted under a manually-adjusted shadow band. Due to the presense of the shadow band a 10% to 18% increase is needed, depending on solar declination for the day of data. Both the corrected and un-corrected diffuse data are provided. | 03/11/2022 | CA | HSU | Eppley | PSP | DHSB |
| 7 | 37501F3 | Diffuse Horizontal | 03/11/2022 | HSU | Diffuse (Sky) shortwave irradiance measured by a PSP mounted under a manually-adjusted shadow band. Due to the presense of the shadow band a 10% to 18% increase is needed, depending on solar declination for the day of data. Both the corrected and un-corrected diffuse data are provided. | CA | HSU | Eppley | PSP | DHSB | |
| 8 | Direct Normal | 03/08/2007 | HSU | Direct (Beam) shortwave irradiance is calculated using the formula: Global = Direct * Cosine(Zenith) + Corrected Diffuse. Note: Direct is set to zero when the Zenith >= 88.5. | CA | HSU | DN | ||||
