Subject: | SGP/EBBR/E26 - Spark Gap Bad, Pressure Incorrect |
DataStreams: | sgp5ebbrE26.b1, sgp15ebbrE26.b1, sgp30ebbrE26.b1 |
Description: | In a trip to E26, I found that a bad spark gap through which the barometer was powered was causing pressure measurements to be incorrect. The pressure readings oscillated with the voltage of the EBBR battery. During daytime the voltage and thus the pressure would increase and vice versa during dark hours. Apparently only the positive side of the power supply was properly connected through the spark gap and thus the voltage received by the pressure sensor was lower than required to power it properly. Under this condition the perssure measurement varies with voltage level. The pressure measurements therefore had a diurnal signature and usually were incorrect. The decreased pressure during most times would cause latent heat flux to be slightly overestimated and sensible heat flux to be slightly underestimated. |

DataStreams: | sgp5ebbrE20.b1, sgp15ebbrE20.b1, sgp30ebbrE20.b1 |
Description: | The E20 pressure sensor suffered from spikes in pressure, which were related to increases in voltage during the day as the solar panels charged the battery. These spikes were not of a magnitude that would affect the 30 minute surface fluxes. Replacement of the pressure sensor solved the problem. |

Description: | The upper dome of the net radiometer was broken. Normally this alone does not affect the net radiation measurement.

Description: | The E26 EBBR pressure sensor experienced the poor internal voltage regulation problem experienced at other sites last year. Aging of the internal voltage regulator caused the pressure output to drop by 1-2 kPa (0.1-0.5 kPa is normal) when the Sun rose and the solar panel goosed the battery voltage up. The sensible and latent heat fluxes were not significantly affected. |
