Subject: | SGP/MWRHF/C1 - 90-GHz questionable calibration |
DataStreams: | sgpmwrhfC1.b1 |
Description: | Between 20061103 and 20070301 one of the parameters thresholds used to select good tip curves used in the calibratio process was not optimal. This resulted in data that have a high standard deviation and a unsatisfactory agreement with model computations. After collecting enough points needed to conduct a model comparison the threshold was changed on March 1. From a limited data analysis for the month pf March it appears that the change in threshold has improved the agreement between measurements and the model. |

Subject: | SGP/MWRHF/C1 - 150-Ghz channel not working |
DataStreams: | sgpmwrhfC1.b1 |
Description: | Starting on 2/23 the 150-Ghz channel is showing a temperature of 310 K. The suspected cause of the problem is a hardware failure. The instrument was removed and sent for repair on 4/2 |

Subject: | SGP/MWRHF/C1 - Dew formation on window |
DataStreams: | sgpmwrhfC1.b1 |
Description: | During night time, when the humidity is very high (RH ~ 100%) data are strongly affected by dew formation on the window. This results in a smooth and large (80-150 K) increase of the brightness temperature from early night to sunrise. Data are affected mostly at night. |
