Subject: | TWP/MPL/C1 - energy monitor spikes |
DataStreams: | twpmplC1.00, twpmplC1.a1 |
Description: | The energy monitor spiked to abnormal values, from 2 up to 25 microjoules per pulse. At the beginning, it was only a few intermittent spikes, but the spikes became more frequent. Most of June does not show a spiky energy monitor. On June 28-30, July 1-10 a diurnal pattern shows up. On July 12-13 it abruptly goes away and returns July 14-16 for 24hrs. Then abruptly stops again 17-19. Except for the 12th, the last changes occurred at 00:00 UTC suggesting a piece of equipment is turning on and off. I do not know why a noisy energy monitor would have a day/night or 00:00UTC dependence. |

Subject: | TWP/MPL/C1 - Energy monitor values are erroneous |
DataStreams: | twpmplC1.00, twpmplC1.a1 |
Description: | Energy monitor values should not be used to normalization the backscatter profiles. A problem with the energy monitor electronics forced the value to maximum. The problem was corrected. |
