Organizers

Technical: Guillaume Vernieres, Thomas Auligne, Travis Sluka

Administrative: Katherine Shanahan

Participants

Anna Shlyaeva (part time), Hamideh Ebrahimi, rahul.mahajan, Shastri Paturi, Stylianos Flampouris, Stephen Herbener (part time)

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

  1. Build/test the SOCA bundle

  2. Centralized server(s) holding observations in their original file formats:

    1. FNMOC

    2. NESDIS: RADS, L-2 SST, CryoSat-2 Thickness

    3. NCEP data tank

    4. SMAP SSS retreivals

    5. EMC sea-ice fraction (SSMI, SSMI-S, AMSR-2)

    6. GODAS observation data base available on Theia

    7. GMAO observation data base available on Discover/Shared Drive
  3. Build Stephen Herbener's IODA-IO, if available (including the python interfaces).

  4. Make sure all current Marine UFO's are in working order (Travis & Guillaume).

  5. Setup HofX and 3DVAR cycling experiment (Rahul, Travis & Guillaume).

  6. 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

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:

  1. ADCP Forward operator
  2. Diurnal sea surface temperature
  3. Sea-ice elevation
  4. sea-ice fraction retreival for SSMI, SSMI-S and AMSR-2 implemented as a pre-filter
