Data information

The data are available here. They are presented with the following directory structure:

• dc_obs_swot/: SWOT data, observations from SWOTsimulator on MITgcm reference;

.
|-- dc_obs_swot
|   |--    SSH_SWOT_XXXXXX.nc

where XXXXX are the dates specifications.

• dc_obs_nadirs/: conventional nadirs data, observations from SWOTsimulator on MITgcm reference;

.
|-- dc_obs_nadirs/*/
|   |-- SSH_NADIR_XXXXX.nc

where * can be one of the available satellites: swot/ (which is the swot nadir), alg/, c2/, j3/, s3a/ and s3b/ ; and XXXXX dates specifications.

• dc_ref_eval: evaluation data, SSH reference from MITgcm during the evaluation period;

|-- dc_ref_eval
|   |-- 2023b_SSHmapping_HF_California_eval_****-**-**.nc

where ****-**-** stands for year, month and day. 

Download and read the data

To start out download the observation dataset (dc_obs) from the temporary data server, use:

wget https://ige-meom-opendap.univ-grenoble-alpes.fr/thredds/fileServer/meomopendap/extract/MEOM/OCEAN_DATA_CHALLENGES/2023b_SSHmapping_HF_California/dc_obs_swot.tar.gz

and

wget https://ige-meom-opendap.univ-grenoble-alpes.fr/thredds/fileServer/meomopendap/extract/MEOM/OCEAN_DATA_CHALLENGES/2023b_SSHmapping_HF_California/dc_obs_nadirs.tar.gz

the reference dataset for the evaluation (dc_ref_eval) using (this step may take several minutes):

wget https://ige-meom-opendap.univ-grenoble-alpes.fr/thredds/fileServer/meomopendap/extract/MEOM/OCEAN_DATA_CHALLENGES/2023b_SSHmapping_HF_California/dc_ref_eval.tar.gz

and then uncompress the files using tar -xvf <file>.tar.gz. You may also use ftp, rsync or curlto donwload the data.
