### Description

The performance of the missing transverse energy (Etmiss) reconstructed with the ATLAS detector is assessed in proton-proton collisions at a centre-of-mass energy of 7 TeV. We report on results in randomly-triggered events, soft proton proton collisions and collisions with jets at high transverse momentum where Etmiss is expected to be zero. Particular attention is given to tails in the Etmiss distribution and a measurement of the Etmiss resolution. The performance of different calibration schemes developed by ATLAS and the individual terms contributing to Etmiss are discussed.
