Subject: | HFE/MWRHF/M1 - 150-GHz data drop out |
DataStreams: | hfemwrhfM1.b1 |
Description: | The sky brightness temperature at 150 GHz (tbsky150) dropped to zero at 12:29 GMT on 20080804 and stayed flat lined until 23:40 GMT on 20081002. |

Subject: | HFE/MWRHF/M1 - Calibration updates |
DataStreams: | hfemwrhfM1.b1 |
Description: | The MWRHF calibration algorithm updates the calibration parameters every time a new successful tip curve is acquired. This results in small jumps (1-2 K) in the brightness temperatures each time calibration is updated. During times of frequent calibrations the data appear discontinuous with short data segments interrupted by small jumps. |

Subject: | HFE/MWRP/M1 - Reprocess: Bias in LWP retrievals |
DataStreams: | hfemwrpM1.b1 |
Description: | Since local radiosondes were not available, radiosondes from a different site were used to develop retrieval coefficients. LWP retrievals are biased in the summer months (June-September). Data in May and December are not affected. Additional analysis will be conducted to derive new retrieval coefficients and the data will be reprocessed. |
