Hi MUSTANG QA folks:
I am having trouble downloading some data from the SALMON projects (ZE
network) from MUSTANG pdf webservice:
http://services.iris.edu/mustang/noise-pdf/1/
The data is used to create a spectrogram with a resolution of 1 day. My
example is shown in the attached file WFLW_pdf_spectrogram.png. However,
sometimes time periods can be missing. Data availability can change
depending on the day. I compared my downloads to the new MUSTANG
spectrogram tool in:
http://services.iris.edu/mustang/noise-spectrogram/1/
and got a complete set of data shown in
WFLW_Z_Spectrogram_IRIS_MUSTANG.png. I also experience the same issue with
TA data. My downloaded data was from a few weeks ago but today I checked
the data again and it is available.
My questions are:
Why does the MUSTANG pdf webservice have missing data when there is not
supposed to be?
Why does data availability change depending on the day?
Why does the MUSTANG spectrogram tool have a more complete set of data?
Thank You,
Kyle Smith

Hi Kyle,
The MUSTANG PDF webservice should not have missing data (except for a recently identified issue that affects days that have a metadata-epoch change; this is in the process of being fixed) and data availability should not change depending on the day. The fact that you are observing this is concerning to us.
Can you give me more information about how you make requests from the noise-pdf service to create the spectrogram? There was a problem that occurred between March-18 to April-19-2019 that potentially affected multiple-day PDF requests, but it should not have affected single day requests.
Best regards,
Gillian
