Subject: | NSA/GNDRAD/C1 - Unreasonable/missing PIR data due to maintenance |
DataStreams: | nsagndrad60sC1.a1 |
Description: | During this period, there are data gaps and the data that were collected are unreasonable. Instrument maintenance was being performed |

Subject: | NSA/GNDRAD/C1 - Noisy PIR Data |
DataStreams: | nsagndrad60sC1.a1 |
Description: | During the period referenced, the ground PIR was noisy in comparison to the sky PIR data. At the end of November, the noise increased to roughly 10 W/m2 from peak to peak. After 12/23/98, the noise decreased in amplitude but still had noisy patterns. On 01/17-18/99, there was an increase again in the noise level (4 GMT 01/17 - 5 GMT 01/18). During this period the gndrad IRT data also exhibited noise patterns (the IRT was not operational). In February, the instrument exhibited large noise variations again. On 02/16, a wiring problem was corrected and the noise dropped back to 1-5 W/m2. However, the noise levels began to increase again. |

Subject: | NSA/GNDRAD/C1 - PIR1 Calibration problems resulted in small error |
DataStreams: | nsagndrad60sC1.a1 |
Description: | The dome correction coefficients were not properly reset in calibration file until the early morning of 12/15. These errors probably account for less than 4% in error. |

Subject: | NSA/GNDRAD/C1 - IRT removed for testing |
DataStreams: | nsagndrad60sC1.a1 |
Description: | The IRT instrument was at PNNL for cold temperature modifications and testing. Instruments returned for the summer season. Data collected after the instrument return looks reasonable. IRT data recorded during the period the instrument was removed is bad. |

Subject: | NSA/GNDRAD/C1 - IRT insufficiently heated |
DataStreams: | nsagndrad60sC1.a1 |
Description: | IRT had insufficient heating to maintain an internal reference temperature above 0 degrees C. Measurements of sky temperature were over-estimated when instrument was below freezing. |
