Subject: | HFE/ECOR/M1 - Sonic failure |
DataStreams: | hfe30ecorM1.b1 |
Description: | The sonic datastream were "garbled", possibly associated with a serial line damage to the LI-7500 serial port or the Versalogic SBC serial port. Garbled data condition existed through 10/09/08 0030 GMT followed by missing data through 10/12/08 0230 GMT. |

Subject: | HFE/SKYRAD/M1 - IRT bias |
DataStreams: | hfeskyrad60sM1.b1 |
Description: | The sky temperatures exhibited a positive bias compared to AERI, especially when < 230K. This is indicative of an incorrect emissivity setting (to compensate for the gold mirror) or a poor calibration. A similar problem with the same instrument occurred during the FKB deployment that was attributed to water vapor. |

Subject: | HFE/ECOR/M1 - Flux Data Incorrect For Some Wind Directions |
DataStreams: | hfe30ecorM1.b1 |
Description: | For some wind directions the horizontal fetch was not representative of the fields surrounding the AMF. Therefore, for the wind direction range 191-349 degrees, the fluxes are affected by insufficient fetch, and surfaces, buildings, and vegetation that are not similar to the local field conditions. |
