Subject: | TWP/MMCR/C3 - Diminished Reflectivity Sensitivity |
DataStreams: | twpmmcrspecmomC3.a0, twpmmcrmomC3.b1 |
Description: | Radar sensitivity was diminished by approximately 15 - 20 dBZ during this period. The result is that upper level cloud tops may be missed and thin clouds, particularly thin cirrus, may not be detected during this period. Reflectivity was correctly calibrated, so values are correct where signals were detected. The problem was caused by lightning damage to the low noise amplifier (LNA). The LNA was replaced on 20060718. |
Suggestions: | Although the reflectivity are accurate, users should be aware that clouds that might normally be seen with a fully functional MMCR might be missed during this period. |
