Data assimilation in the laboratory using a rotating annulus experiment by Young, R, Read, P

“…Our assimilated observations are irregularly distributed, which is more meteorologically realistic than gridded observations as used in recent applications of data assimilation to laboratory measurements. We demonstrate that data assimilation can be used successfully and accurately in this context. …”
