In this note I use the ERS wind processing chain to simulate noisy backscatter values for ASCAT, retrieve winds from those, and compare them to the "true" wind. It is shown that, in order to achieve a constant performance versus across track node number, the instrument noise may be larger at the outer parts of the swath. This effect is quantified, and 25 versus 50 km resolution is investigated.
