Dear colleagues,

The solar panel angle dataset f= or SWOT has been completed.

The swoqsolp* files are now ava= ilable from 31/01/2023 at the IGN data center.

(ftp://doris.ign.fr/pub/doris/a= ncillary/quaternions/swo/)

These are daily files. For day = D, data start at D-1 23:59:23 and end at D 23:59:23

Note that the file for 23/11/20= 24 (swoqsolp20241122235923_20241123235923.001.xml) does not exist.

There were two series of files = for the period 20/03/2024-28/05/2024

Only the series “D-1 23:5= 9:23 - D 23:59:23” is now available, the other has been deleted.=

Two files have been redelivered= because they had been stored with zero size:

swoqsolp20240909235923_20240910235923.001.xml

swoqsolp20240917235923_20240918235923.001.xml

Reminder: An instrumental correction must be added to the value of the solar p= anel angles (add +0.2=B0 to Solar Panel 1 angle,

add -0.2=B0 to Solar Panel 2 an= gle). See htt= ps://ids-doris.org/documents/BC/ancillary/quaternions/swot_solar_panel_CNES= _product_description.pdf<= /p>

The bias is due to a small misa= lignment on the platform and is not included in the angles extracted from t= he telemetry and made available for POD activities and IDS.

In addition:<= /p>

- the quaternions in netcdf for= mat have been removed (swoqbody*.nc). Only the dataset in “Jason-3 li= ke” format is supplied (swoqbody* without extension);

- the storage of the swoqsolp a= nd swoqbody files to the CDDIS data center is in preparation.

If you have any questions, plea= se do not hesitate to contact the Central Bureau

Best regards,

Laurent Soudarin
