Subject: | TWP/SKYRAD/C1 - Failed PSP ventilator fan |
DataStreams: | twpskyrad60sC1.b1, twpskyrad20sC1.a0 |
Description: | On 1/31 the ventilator for the PSP measuring downwelling_shortwave_hemispheric irradiance failed. The DQ effect of this failure on the measurement of down_short_hemisp is not possible to fully quantify but it has been noted that during these failures the PSP nighttime values can be several (1-3W/m2) smaller than usual. Another effect is slower thermal response (1hr) of the PSP instrument due to daytime heating and cooling of the ventilator housing. |
Suggestions: | Use data with caution. |
