| Description: | The cmask, temperature, and pressure fields are using improper metadata for the long_name
variable attribute. In each of these fields, the long_name changes depending on the
sourceused for each field. This creates a conflict with the DOD version listed in the global
attributes for these datastreams, as the long_name should be static for a specific DOD
version. This VAP is listing a single DOD version despite these differences. This creates a
problem with the metadata stored in the Archive databases, which also expect the
long_name for a field to be constant over time.
As a result, the long_name listed for the temperature field in the "Extract Specific
Measurements" option of the Archive Data Discovery ordering interface is "Temperature from
sgpaeriprof3feltzC1.c1". When you actually examine the data files, the temperature field
for this product may have one of the following long_names:
temperature:long_name = Temperature from sgpaeriprof3feltzC1.c1;
temperature:long_name = Temperature from sgplssondeC1.c1;
temperature:long_name = Temperature from sgpsondewnpnC1.b1;
Likewise, the long_name listed for the pressure field in the "Extract Specific
Measurements" option of the Archive Data Discovery ordering interface is "Pressure from
sgpaeriprof3feltzC1.c1". When you actually examine the data files, the temperature field for this
product may have one of the following long_names:
pressure:long_name = Pressure from sgpaeriprof3feltzC1.c1;
pressure:long_name = Pressure from sgplssondeC1.c1;
pressure:long_name = Pressure from sgpsondewnpnC1.b1;
Finally, the long_name listed for the cmask field in the "Extract Specific Measurements"
option of the Archive Data Discovery ordering interface is always "Cloud mask from
depolarization VAP". The user will need to check the long_name in the individual data files to
determine if the long_name is actually "Cloud mask from depolarization VAP" or "Cloud
mask from ASR VAP". In addition, the data type of the cmask field changes depending on the
source. If the long_name is "Cloud mask from depolarization VAP", the data type is "int".
If the long_name of the cmask field is "Cloud mask from ASR VAP", the data type if "float". |
| Suggestions: | Users should check each data file to determine if the temperature and pressure fields
were actually obtained from sgpaeriprof3feltzC1.c1, sgplssondeC1.c1, or
sgpsondewnpnC1.b1. In addition, the user will need to check the long_name of the cmask field in each
data file to determine if the field was derived from the depolarization VAP or ASR VAP.
The user also should be aware that the data type of the cmask field will be integer if the
field was derived from the depolarization VAP, and float if the cmask field was derived
from the ASR VAP. |
