Subject: | PGH/NFOV/M1 - Instrument noise/interference |
DataStreams: | pghnfov2chM1.b1 |
Description: | When the signals are very low, a regular feature can be seen in the data. It begins on the hour, and lasts for ~20 minutes. This feature is a rise in the signal of 0.25 to 0.33 mV. It is small even when compared with the NFOV's typically small signals. My initial hunch is the NFOV is located next to or nearby equipment that operates/broadcasts/etc beginning on the hour, and lasting for ~20 minutes. Looking (very closely) back at the previous deployment, this regular signal bump is also evident, so it seems the equipment contaminating the NFOV is part of the AMF1, and not unique to this deployment. 20111222 is a good example of the issue. |

Subject: | PGH/GNDRAD/M1 - Reprocess: Incorrect calibrations |
DataStreams: | pghgndrad20sM1.a0, pghgndrad60sM1.b1 |
Description: | During the entire India deployment the Gndrad system was configured with incorrect calibration coefficients for the shortwave instruments. The program hadn't been updated since the previous deployment in the Azores. The instrument mentor, site personal and OSS support have attempted to best determine the serial numbers of instruments installed at PGH during the deployment period. The following instrument data will need to be reprocessed with the following correction multipliers: PIR-UIR(up_long_hemisp): OK, no correction required PSP-US (up_short_hemsip): 117.97(correct)/129.42(incorrect) = 0.91153 IRT: calibration should be validated by instrument mentor (Vic Morris): mult=25, offset=223.2 Correct serial numbers: PSP-US (up_short_hemsip): 33941F3 |
