Deliverables
Note: Testing will be done within the cycling of SOCA 3/4DHofX and/or 3DVAR.
- Applications that can be embedded in the SOCA workflow and will create observation files in a IODA format for a specific DA or HofX window.
 
- New UFO’s: Cool skin, and generic implementation of Salinity profiles and sea surface salinity.
 
- Report/Reflection on code sprint.

Table 1: Tabulated list of deliverable. Check the empty box when done.
Prerequisites, to do before March 25
Build/test the SOCA bundle
Centralized server(s) holding observations in their original file formats:
FNMOC
NESDIS: RADS, L-2 SST, CryoSat-2 Thickness
NCEP data tank
SMAP SSS retreivals
EMC sea-ice fraction (SSMI, SSMI-S, AMSR-2)
GODAS observation data base available on Theia
- GMAO observation data base available on Discover/Shared Drive
 
Build Stephen Herbener's IODA-IO, if available (including the python interfaces).
Make sure all current Marine UFO's are in working order (Travis & Guillaume).
Setup HofX and 3DVAR cycling experiment (Rahul, Travis & Guillaume).
Prepare the nonlinear, tangent and adjoint of the cool skin UFO. (Hamideh & Guillaume).
Tentative Work plan
Some of us will work on the UFO during the 2 weeks, but for the most part, week 1 will be on IODA interfaces and week 2 on UFO's.
Week 1: IODA interfaces
Objectives: Provide observations to SOCA for cycling experiments. Develop interfaces to databases for NOAA/EMC and NASA/GMAO, usable in the SOCA cycling workflow. We will make use of Stephen Herbener's IODA-IO python package, if available.
Note: Describe the observation type you are working on in Stephen Herbener's IODA wiki.
Week 2: UFO
We will reassess our week 2 objectives at the end of the first week. In the meantime here is the tentative work plan: Refactor the existing marine UFO and implement new UFO’s (including the basic QC needed to run a 3DVAR application).
Required tasks
- Anna Shlyaeva: Fix issues with the GeoVaLs writer
 - gvernier & Travis: Implement needed GeoVaLs for QC and new UFO in SOCA 
 
Refactoring or Generic implementation
- Insitu-profiles
 - Salinity (generic)
 - SST (generic)
 - SSS (generic)
 - Sea ice fraction
 - Sea-ice thickness
 - ADT
 - Cool skin (new UFO)
 
Extras
If time permits:
- ADCP Forward operator
 - Diurnal sea surface temperature
 - Sea-ice elevation
 - sea-ice fraction retreival for SSMI, SSMI-S and AMSR-2 implemented as a pre-filter
