NPACNFS DATA ASSIMILATION

	Observations
	Altimeter GFO, TOPEX/Poseidon, ERS-2 dSSH	AVHRR SST	(BTs) XBT, CTD Temp/Sal Profiles
	Data Analysis MODAS (Modular Ocean Data Assimilation System) dSSH(x,y) = OI [ dSSH(track) ] ; SST(x,y) = OI [ SST(pixel) ] dT(x,y,z)synthetic = fz (dSSH(x,y),SST(x,y)) T(x,y,z)analysis = T(x,y,z)clim + OI [ dT(x,y,z)synthetic | dT(x,y,z)BT ]
	Data Assimilaton T*model = Tmodel + (dt/Tscl) f(z) (Tanalysis - Tmodel)
