DataStreams: | sgp1smosE9.a0, sgp30smosE9.a1 |
Description: | EDITOR'S NOTE: The earliest portion of the period of time covered by this DQR occurred prior to the begin data of regular ARM data. Those data are not readily available from the ARM archive but are available upon request. The actual period of time covered by this DQR is 930331.0000-930823.2359. Practically all of the information in this DQR is derived from P930723.1 and C930830.1, both of which were submitted by Dick Hart. The calibrations initially used for wind speeds on SMOS systems at Coldwater (E8), Ashton (E9), the central faciality (E13), Ringwood (E15), and Meeker (E20) were originally "generic"values, but analysis of the N.I.S.T traceable calibration data reveals that use of these "generic" calibrations produces data with insufficient accuracy. The calibrations for the wind speed sensor associated with the instrument must be used in the datalogger program in order to obtain data with a 1% uncertainty. For the worst case, one wind speed sensor underestimates the wind speed by 1.1 m/s at 30 m/s when the "generic" calibration is used. This is on top of the 1% calibration uncertainty. No unreported data loss occurred as a result of this calibration question, but users of the data should adjust the wind speed values before analysis involving these wind speed values. |

Description: | During a rain storm the relative humidity readings (and vapor pressure which is derived from RH) became erroneous. The sensor electronics may have gotten wet. The sensor recovered from whatever problem occurred e.g., the sensor dried out). No permanent damage occurred. No other measurements appear to have been affected. Temperature measurements during the period in question, agree with those obtained by the EBBR. |
