Interpolate L4 to MOM6

[ShastriPaturi]

Interpolate L4 data to MOM6 0.25 grid

• [ ] L4 ADT (Register and download data from https://cds.climate.copernicus.eu/cdsapp#!/dataset/satellite-sea-level-global?tab=form for July 2021. Downloaded raw data from 202108 is here: /work2/noaa/ng-godas/jhossen/adt_coperl4_raw/)
• [ ] L4 NSIDC ice conc (/work/noaa/da/jszhu/DATA/obs/nsidc/raw/2021) Use for example 2021/20210701/seaice_conc_daily_nh_20210701_f17v04r00nw.nc . The file with extension nw has latitude and longitude in them.
• [ ] L4 Copernicus ice thickness (Low priority) (Monthly data: /work2/noaa/ng-godas/jhossen/icethk_coperl4_raw)

@ShastriPaturi Thank you.

@ShastriPaturi Interpoated adt into global 0.25 degree is here: /work2/noaa/stmp/yongzuo/L4/OUTPUT

Thanks @YongzuoLi-NOAA . What period did you prepare? @ShastriPaturi , can we move these into our common space on Hera and Orion?

Thanks @YongzuoLi-NOAA. July 2021

@YongzuoLi-NOAA what is the white line around the 180deg ?

[YongzuoLi-NOAA]

Here is fixed adt interpolation /work2/noaa/stmp/yongzuo/L4/OUTPUT Issue: MOM6 lonh=-180.1133W means 179.8867E for L4 (-179.875W -> 179.875E), being considered "outside L4". Solution: adt(-180.1133W)=adt(left (or right) of -180.1133W) more figures

[YongzuoLi-NOAA]

Ice data over NH and SH are from 3 sources of Climate Data Record, NASA Team, and Bootstrap. Figures

[ShastriPaturi]

@YongzuoLi-NOAA please use 'cdr_seaice_conc' (Climate Data Record) as the icec variable.

[ShastriPaturi]

@YongzuoLi-NOAA, can you please extend the L4 ADT interpolation from August, 2021 till April, 2022 please?

[ShastriPaturi]

Thanks @YongzuoLi-NOAA . What period did you prepare? @ShastriPaturi , can we move these into our common space on Hera and Orion?

@guillaumevernieres, interpolated data are in common place: Orion: /work2/noaa/ng-godas/common/validation/ Hera: /scratch2/NCEPDEV/marineda/validation/

[YongzuoLi-NOAA]

@YongzuoLi-NOAA, can you please extend the L4 ADT interpolation from August, 2021 till April, 2022 please?

Will do so.

@ShastriPaturi L4 ICE to MOM6 interpolation: /work2/noaa/stmp/yongzuo/L4/ICE/OUTPUT Compare with obs plot https://github.com/NOAA-EMC/godas/issues/386 L4 ICE was interpolated into global ¼ degree MOM6 for January 2021 - December 2021.
