Narrative:

I was about final for runway 16R at vny. A corporate jet (I believe it was a citation) had preceded me. Upon receiving my landing clearance while on downwind (including 'follow the citation for whatever; you're number two);' I remember having received the obligatory 'caution wake turbulence' from the tower. I waited until the jet was well past my '45' before turning base. I did so approximately at the va hospital; which is a frequent location referenced during pattern or approach work at vny. I was at a deliberately slow 70KIAS. I asked the tower for a wind check when I was about 4 miles out; and heard; 'wind calm.' I did notice that I needed a very slight left crab on final. At about 1.5 miles out; I experienced a left-wing-lifting; rolling encounter I assumed was from the previous aircraft's wake turbulence. It was a very distinct yet rather gentle roll from level wings to approximately 40 degrees left wing high. I recovered quickly and experienced no subsequent unusual wind encounter prior to touchdown. Pilots hearing 'wind calm' on the runway should keep in mind that ground friction and other local obstructions may change the wind's characteristics immediately above the runway; and that 'wind calm' does not guarantee calm winds above ground effect.
