Subject: | SGP/MWR/C1 - Radio Frequency Interference during IOP |
DataStreams: | sgpmwrlosC1.b1, sgp5mwravgC1.c1, sgpmwrlosC1.a1 |
Description: | During the specified times a strong, continuous signal was measured by the 31.4 GHz of the MWR. The signal was present in all 31.4 GHz measurements including the sky measurement, the internal reference target measurement, and the measurement of the internal noise injection source from which the instantaneous instrument gain is computed. The source of the interference has not yet been identified. Because the gain is computed using the difference of the noise injection and target measurements, and because the sky brightness temperature is computed relative to the internal target temperature, the data appear anomalous only for a period of an hour after the interference starts and ends. This is due to the low pass filter applied to the instantaneous gain. However the data should be considered invalid or at least questionable during the entire period for which the interference was present. |
