Data access in Python

• Data Access
  • servers, servers everywhere and not a bit to flip

• My day job: IOOS
• Big or small we need data!
• Feedback
• Web Services/Type of servers
• What are we going to see in this tutorial?
• 1) ERDDAP
  • Learning objectives:
• What is ERDDAP?
  • What services are available in the server?
  • Let’s query all the datasets that have the standard_name of sea_water_practical_salinity.
  • Let us narrow our search to deployments that within a lon/lat/time extent.
• 2) OPeNDAP
  • Learning objectives:
• 3)

  • Learning objectives:
• 4) WMS
  • Learning objectives:
• 5) Catalog Service Web (CSW)
  • Is there a canonical source for data?
• Catalog Service for the Web (CSW)
• For more complex examples on how to find data in the catalog please check the IOOS code gallery:
• Where to find data?
• Extras: how does this all work?
• Standards!
• Bad example
• Good example
• Extras: load netCDF files directly from HTTPS
• Data Clean Up (QARTOD)
• Quality Assurance/Quality Control (QA/QC) configuration
• data from the AOOS ERDDAP server
• Run the QC
• Function to plot the results
• Gross Range test
• Spike test
• Flat Line test
• First create the erddapy object
