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. |
