Subject: | FKB/MWRHF/M1 - Dew formation on window |
DataStreams: | fkbmwrhfM1.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. |

Subject: | FKB/MWRHF/M1 - Reprocess: Surface Relative Humidity too low |
DataStreams: | fkbmwrhfM1.b1 |
Description: | The surface relative humidity readings are too low when compared with the MWRP and the tower sensor. |

Subject: | FKB/NFOV/M1 - Intermittent problem with channel 870 |
DataStreams: | fkbnfov2chM1.b1 |
Description: | At times channel 870 is erratic. Fortunately, it is mostly at night when it is not functioning properly. The erratic behavior is infrequent until Sept when it becomes a bit more frequent. Even then, however, very little daytime data are affected. |

Subject: | FKB/MWRHF/M1 - Questionable calibration |
DataStreams: | fkbmwrhfM1.b1 |
Description: | The instrument completed a tip curve calibration on June 30 and it did not calibrate again until Oct 13. Data during this time display large residuals (~ 6 K) when compared with model computations. It is likely that the tip curve calibration, although successful, wasn't good enough to have good accuracy. Since this instrument is still under testing the users should use the data with caution. Although the accuracy of the model itself is still debated, large residuals between the measurements and the model between June and October are probably in large part due to the poor calibration. |
