HFE/MWR/M1 - Insufficient calibration stability

The noise diode temperature suddenly jumped to > 60 C after a power outage. Following 
additional power problems the noise diode injection temperature drifted fast and the 
radiometer was not able to calibrate properly.

Data during the indicated time periods are poorly calibrated and sometimes erratic. Users 
should be aware that the accuracy of the measurements is dramatically degraded. 

Users can use the microwave profiler (MWRP) data to supplement the MWR data.

HFE/ECOR/M1 - Sonic failure

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.

HFE/MET/S1 - Barometer missing

All spare barometers and the working barometer for this supplemental site were damaged 
during shipment.  They were sent in for repair and recalibration.

• Atmospheric pressure(atmos_pressure)

HFE/MET/S1 - Optical Rain Gage Failed

All data collected by the ORG is of no use.  The ORG had failed and any data collected was 
not indicative of the current weather.

HFE/MET/S1 - Wind Data Incorrect

The wind sensor became disconnected and no wind speed or direction data were collected.

• wind_spd_arith_max
• Vector-averaged Wind Speed(wind_spd_vec_avg)
• wind_spd_arith_sd
• Vector-averaged Wind Direction(wind_dir_vec_avg)

HFE/ECOR/M1 - Flux Data Incorrect For Some Wind Directions

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.
