Description: | The EF data system lost communication with the GPS likely starting on or around June 7th,
the max time set For E21 was -5.04 sec. Since then, it has been increasing steadily:
Jun 8 Offset: -267.449039
Jun 9 Offset: -541.038624
Jun 10 Offset: -814.469141
Jun 11 Offset: -1076.862114
Jun 12 Offset: -1350.330223
Jun 13 Offset: -1623.639335
Jun 14 Offset: -1897.047754
Jun 15 Offset: -2170.552312
Jun 16 Offset: -2422.130746
Jun 17 Offset: -2684.607495
Jun 18 - Jun 22 (unknown)
Jun 23 Offset: -4204.730579
If the E21 system clock drifts the E21 Datalogger clocks will be set to the same incorrect
time. SIRS irradiance data will be correct but the corresponding time stamp cannot be
accurately known or simply corrected for. |
