Subject: new IGN/JPL DORIS weekly series using GRACE gravity field model 

Dear colleagues,

following the availability of the new gravity models issued from 
GRACE data (U. Texas/JPL solution GGM01C), we have recomputed the 
entire DORIS data set (Jan 1993 - August 2003).

The IGN/JPL weekly sinex solutions are available for you at :

	ftp cddisa.gsfc.nasa.gov
	cd pub/doris/products/sinex_series/ignwd

Using the regular naming convention, there are 2 new DORIS series there :

	ignwd04	= transformed and projected (coordinates directly in ITRF2000)
	ignwd05	= no tranformation, no projection (free-network solutions)

These solutions also include daily EOP and derivatives as previously done.

Description files have also been posted.

A derived global solution (positions/velocities) and geocenter series 
will soon be added.

Please feel free to contact me if you have any questions about these solutions.
Have a Merry Xmas
Pascal

NB: we plan to extend these series on a regular basis in the future, 
when more recent DORIS data will be available.
