Description: | Suntracker failed at this facility. The suntracker was reset on 9/17, but this only temporarily fixed the problem and the tracker began failing again 9/18. Tracker was reset and realigned on 10/15/03 17:30GMT. Documented in instrument DQR D030922.4 |

Description: | Possible main power problem made may have caused the tracker to fail. Attempts to restart the old tracker, subsequent replacement and lack of spares contributed to incorrect data from the NIP (short_direct_normal datastream) and 8-48 (down_short_diffuse_hemisp datastream) until the time of site decommissioning. This facility was decommissioned and maintenance efforts ceased 10/1/2009. The instrument was removed from service 12/04/2009. Documented in instrument DQR D090609.1 |

Description: | Logger reverted to previous years configuration, possibly due to power outage and non-current logger program in storage module. Note, the tracker had failed during this period as well. The configurations are as follows: Correct S/N and coefficients for this station during this time Diffuse PSP: 33268F3 PSP-US: 30811F3 NIP: 29578E6 PSP-DS: 30903F3 Diffuse PSP: 118.49 W/(m^2*mV) PSP-US: 116.66 W/(m^2*mV) NIP: 123.30 W/(m^2*mV) PSP-DS: 128.92 W/(m^2*mV) Incorrect S/N and coefficients applied during this time range. Diffuse PSP: 33366F3 PSP-US: 30961F3 NIP: 29009E6 PSP-DS: 20386F3 Diffuse PSP: 111.68 W/(m^2*mV) PSP-US: 111.85 W/(m^2*mV) NIP: 111.03 W/(m^2*mV) PSP-DS: 104.15 W/(m^2*mV) Data must be reprocessed for all shortwave instruments; longwave instruments are unaffected. The following corrections must be applied: down_short_diffuse_hemisp(new) = down_short_diffuse_hemisp(old) * 118.49/111.68 up_short_hemisp(new) = up_short_hemisp(old) * 116.66/111.85 short_direct_normal(new) = short_direct_normal(old) * 123.30 / 111.03 down_short_hemisp(new) = down_short_hemisp(old) * 128.92 / 104.15 |
