Subject: | NSA/GNDRAD/C1 - Noisy PIR Data |
DataStreams: | nsagndrad60sC1.a1, nsagndrad60sC1.b1 |
Description: | During the period referenced, the ground PIR was noisy in comparison to the the sky PIR data. (Note U021211.1 documents same problem for 9/1/98-2/28/99) The noise problem continued after the GNDRAD data logger was replaced in late September. Particularly strong examples of the noise can be seen in data from 11/10 - 11/19/99. The peak to peak noise reaches 12 W/m2. |

Subject: | NSA/GNDRAD/C1 - IRT data noisy |
DataStreams: | nsagndrad60sC1.a1, nsagndrad60sC1.b1 |
Description: | After re-installation of the IRT on 12/10/99, the data are noisy. Source of the noise is believed to be the heater connected directly to the IRT. Instrument was taken offline on 12/30/1999 and shipped back to PNNL for repair/testing. |
