| Description: | The Automatic Exchange Mechanism would not function. It was decided to
take the unit back to SGP CART to try to repair it. A spare AEM was not
available for a replacement, so the aspirated radiation shields housing
temperature and humidity gradient sensors were attached to the EBBR
framework, one meter apart vertically, with the right side in the lower
position. The housings remained this way for two weeks. During this time
period, home signal, sensible heat flux, and latent heat flux values are
incorrect. Significant reprocessing would be required to obtain correct
fluxes, and that would be possible only if one assumed that offsets in the
sensor calibrations are negligible; that is a very debatable assumption
considering that the EBBR system is already half a year past due for
calibration. |
