Subject: | SGP/SMOS/E13 - Error in Snow Depth Output |
DataStreams: | sgp1440smosE13.a0, sgp30smosE13.a1 |
Description: | Dick Hart of ANL proposed a change in the frequency of sampling of snow depth by the SMOS, to obtain a more accurate measurement. He modified the SMOS CR10 program in December 1995 but did not have the opportunity to ask for it to be implemented. In January, acting in Dick's behalf, I forwarded the changes to site operations, along with a Baseline Change Request (BCR). The changes were implemented in the Central Facility (E13) SMOS only on 29 January 1996 for testing. Within a few days it was clear that the snow depth measurement was not being made properly. The common outputs for snowdepth were 0.0 or 895.0 (895.0 data is incorrect). I reviewed the CR10 program and found that some further changes were needed. I then submitted these changes to site operations along with another BCR. The changes were implemented in the CF SMOS only on 6 March 1996. Snowdepth data since that date has been correct. The program changes can now be implemented in the other SMOS CR10s; the changes will be transparent to the data user. |

DataStreams: | sgp1440smosE13.a0, sgp1smosE13.a0, sgp30smosE13.a1 |
Description: | The values of relative humidity reported by the SMOS at E13 between 18 NOV 96 and 1930 GMT on 30 JAN 97 are too high. Saturation values of 104% to 105% have been reported during this period. A 6-month Verification Check was made on 18 NOV 96 and the SMOS probe did not agree with the reference at that time. The SMOS probe was finally replaced on 30 JAN 97. Data reported since that time appears reasonable. |

DataStreams: | sgp1440smosE13.a0, sgp1smosE13.00, sgp30smosE13.a1 |
Description: | When the E13 SMOS naturally aspirated radiation shield was replaced with a fan aspirated radiation shield on 14 APR 95 at 2030 GMT, the new shield was not adequately sealed to prevent penetration of water, whether from rain or from dew, from entering the radiation shield and causing incorrect humidity data. After numerous attempts, the radiation shield was successfully sealed early in NOV 95. Separate DQR's have been issued for humidity data that was obviously erroneous, but on numerous occasions during that period the humidity data has looked suspicious (e.g., see PIF P960624.1). Therefore, all humidity data reported by the E13 SMOS during that period should be considered questionable. |
