Subject: | SGP/SIRS/E8 - Ventilator Fan Failure |
DataStreams: | sgpsirsE8.00, sgpsirsE8.b1, sgpsirs20sE8.a0 |
Description: | At the start time specified the PSP (down_short_hemisp) ventilator fan failed. PM replaced the fan 7/8/2008 1750. Ventilator failure does adversely affect radiometer measurements but the extent has not been quantified. Mentor suggests using component sum method detailed in SIRS instrument handbook where down_short_hemisp = down_short_diffuse + short_direct_normal * cos (zenith angle) for each time record. |
Suggestions: | Use down_short_hemisp with descretion or apply component sum method. |
