SGP/SMOS/E7 - Questionable Humidity data

Editor's note:  A portion of the period of time to which this DQR 
applies is prior to the begin date of regular ARM data collection.  
The actual begin date of the problem described in this DQR is 950224.0400.

All SMOS E7 humidity data taken during this period are questionable.
The sensor was replaced several times. A "good" sensor was finally 
installed on 17 MAY 95 at 1732 GMT.

All humidity data (RH, vapor pressure, and their standard deviations) 
taken during this period should be flagged as questionable.

• Maximum Vapor Pressure(max_vap_pres)
• Time of Relative Humidity(time_min_rh)
• Minimum Relative Humidity(min_rh)
• Daily maximum relative humidity(max_rh)
• Time of maximum vapor pressure(time_max_vap_pres)
• Daily minimum vapor pressure(min_vap_pres)
• Time of minimum vapor pressure(time_min_vap_pres)
• Time of maximum relative humidity(time_max_rh)

• Standard Deviation of Relative Humidity(sd_rh)
• Standard deviation of vapor pressure(sd_vap_pres)
• Relative Humidity (hybrid-b grid)(rh)
• Vapor Pressure (kiloPascals)(vap_pres)

• Relative Humidity (hybrid-b grid)(rh)
• Vapor Pressure (kiloPascals)(vap_pres)
