Subject: | SGP/MWR/B1 - Loss of thermal stabilization |
DataStreams: | sgpmwrlosB1.a1, sgpmwrB1.00, sgpmwrlosB1.b1, sgpmwrlosB1.00, sgpmwrlosB1.a0 |
Description: | As described in DQR D040819.3 during the month of August in 1994 and 1995 the microwave radiometers would lose thermal stabilization on very hot sunny days when the temperature in the radiometer enclosure rose above the set point for thermal stabilization (~50 degC). The temperatures in July 1996 were hotter than in previous years and the loss of stabilization problem occurred before the instrument mentor could make the needed adjustment. The purpose of this DQR is to identify the time periods for which this problem occurred. More specific information about the problem, including how the problem is detected and its effect on the reported values of integrated water vapor and integrated cloud liquid water are provided in DQR D040819.3. When the thermal stabilization is lost, the reported precipitable water vapor increases and the liquid water path decreases (and becomes SIGNIFICANTLY NEGATIVE (-0.1 mm) on clear sky days). The RMS noise level in the data also increases sharply. THESE ANOMALOUS VALUES HAVE BEEN INCLUDED IN THE 5-MINUTE AVERAGES. |
