NSA/METTWR/C1 - CMH Dew Point and RH data Incorrect
DataStreams:nsamettwr4hC1.b1
Description:
The Chilled Mirror Dew Point reported negative dew point values.  This caused the RH to be 
much lower than reality also.  Compared to the 2m level the RH and dew point from the 
CMH are incorrect.  Mirror was dirty, it was removed, cleaned and recalibrated.

NSA/METTWR/C1 - Instrument problem, Contamination, False signal
DataStreams:nsamettwr4hC1.b1
Description:
Heavy, wet and blowing snow and ice caused measurement problems with the sonic anemometer 
mounted at the 2m level.  Erroneous readings caused both the wind speed and direction 
values to be reported anomolously.  Once the heavy, wet snow and ice stopped the readings 
returned to normal.

NSA/METTWR/C1 - 20m Temperature/RH Sensor Failing
DataStreams:nsamettwr4hC1.b1
Description:
The 20m temperature and RH sensor began reading high on 20040719.
Aspirator fan failure caused a portion of the high reading.  New fan
failed to correct for all errors.  Sensor replaced on 20040908 with
recently calibrated sensor.

DataStreams:nsamettwr4hC1.b1
Description:
The 2m T & RH values were not in very good agreement with the CMH data or the other tower 
levels.  A failed aspirator fan caused the readings to be incorrect.

Description:
The max values for cumulative rain sum of 99 mm and the rain rate of 999 mm/hr are 
incorrect.  In communication with the manufacturer it has been found that the manual was in 
error.  The actual max values of the cumulative rain sum is 99.99 mm and the rain rate is 
999.99 mm/hr.

Description:
The CMH mirror was in need of cleaning.  The data is suspect from 05/28/05 through 
07/04/05 as intermittently poor readings occurred.  After 07/04/05 the data was incorrect as the 
mirror was excessively dirty.

NSA/METTWR/C1 - Tower Maintenance
DataStreams:nsamettwr4hC1.b1
Description:
The booms of the tower were lowered for sensor replacement, calibration, and tower 
maintenance.  During the maintenance and sensor replacement data are frequently missing.  Where 
data are available, they are not or may not be representative because the booms were at 
the base of the tower during the time period listed.

The chilled mirror measurements were not affected by the maintenance.

NSA/METTWR/C1 - 2m Datalogger Failed
DataStreams:nsamettwr4hC1.b1
Description:
The 2m temperature, wind speed, wind direction, and relative humidity were reporting the 
missing value (-9999).
Measurements:nsamettwr4hC1.b1:
  • WD2M_SDU_WVT
  • Relative humidity, average, at 2-m height(RH2M_AVG)
  • Wind speed, mean, at 2-m height(WS2M_S_WVT)
  • T2M_STD
  • DP2M_STD
  • Temperature, air, average, at 2-m height(T2M_AVG)
  • Temperature, dew point, average, at 2-m height(DP2M_AVG)
  • RH2M_STD
  • Wind speed, vector-averaged, at 2-m height(WS2M_U_WVT)
  • RefT2M_AVG
  • VP2M_STD
  • Volt2M_AVG
  • Pressure, vapor, at 2-m height(VP2M_AVG)
  • Wind direction, vector-averaged, at 2-m height(WD2M_DU_WVT)

NSA/METTWR/C1 - CMH required Calibration
DataStreams:nsamettwr4hC1.b1
Description:
The Chilled Mirror was showing some signs of being out of calibration.  Temperatures were 
at times higher than co-located temp probes and the dew point temperature values at times 
were not consistent with co-located RH sensors.
Measurements:nsamettwr4hC1.b1:
  • VPCMH
  • SatVPCMH
  • CMHDP
  • CMHTemp
  • CMHRH

NSA/METTWR/C1 - 2m level data incorrect
DataStreams:nsamettwr4hC1.b1
Description:
The 2m data for temp, RH, dew point, wind speed wind direction & vapor pressure were 
incorrect.  The voltage values for the datalogger at that level were reporting as 60V with 
excursions to 100V.  These values should have damaged the logger at that level.  After an 
extended power outage on 08/04 the data all became reasonable. There is no explanation as 
to the cause of this failure.
Measurements:nsamettwr4hC1.b1:
  • WD2M_SDU_WVT
  • Relative humidity, average, at 2-m height(RH2M_AVG)
